A customer came to us with a requirement that sounded simple at first:
They needed an indoor ground-support structure for an LED screen.
But there was one important condition.
The structure could not be designed for only one LED screen configuration.
The customer wanted the same support system to work with:
flat LED screens;
curved LED screens;
different curved-screen angles;
different overall LED screen widths.
More importantly, the customer did not want to purchase a different set of structural components every time the LED configuration changed.
That turned a normal LED support-frame request into a different design question:
How could we make the structure change with the LED screen while keeping the main structural components the same?
The answer eventually came from one part of the structure:
the base.
The customer's first requirement was straightforward:
The support structure would be used indoors, but sometimes the LED wall would be flat and sometimes it would be curved.
One obvious approach would have been to treat these as two different structures.
A flat LED wall could use one base arrangement.
A curved LED wall could use another.
But that immediately conflicted with the customer's second requirement:
The same set of materials should be reused. The customer did not want to buy additional structural sets simply because the screen shape changed.
That requirement became one of the most important constraints in the design.
The objective was therefore not simply:
Design a curved LED support frame.
It became:
Design one modular support system that can be rearranged for different LED geometries.
For readers looking for our broader LED support product range rather than the decision process behind this particular design, see our LED Truss systems.
If the customer had only needed one predetermined curved screen, the problem would have been much easier.
We could have designed the supporting geometry around that particular curve.
But that was not the requirement.
The curvature could change from one LED installation to another.
That meant the angle between neighboring support positions also had to change.
A fixed-angle base would solve only one configuration.
Once the LED wall changed its radius or shape, the same fixed base geometry might no longer match it.
So the third requirement became:
The structure needed to accommodate changing angles rather than one predetermined curved-screen angle.

This drawing is particularly useful because it makes the problem visible immediately: viewed from behind, the support frames are no longer arranged along a single straight axis.
Angle was only one variable.
The customer's LED screen width could also change.
A wider screen means the support positions have to spread farther apart.
A narrower screen brings them closer together.
So now we had two independent geometric variables:
Angle changes
→ caused by flat versus curved LED layouts and different curvatures.
Distance changes
→ caused by different LED screen widths.
If every change required a new fixed base component, the customer would eventually accumulate multiple sets of parts.
That would defeat the original requirement.
The customer wanted one set of materials.
So instead of continuing to modify the entire rear support frame, we began looking for the point where both variables could be controlled.
This was the key design decision.
The vertical rear frames and supporting members already had a clear structural function.
The real geometric change happened at floor level:
Where should each support frame stand, how far should it be from the next one, and at what angle should it face?
Once we looked at the problem this way, the design direction became much clearer.
Rather than producing different complete structures for different LED layouts, we concentrated the adjustment capability into the base connection system.
The base needed to perform two jobs:
change distance;
change direction.
That led to the adjustable base shown in the actual fabricated components below.

Actual fabricated adjustable LED support base. The telescopic base member allows the spacing between support positions to be changed rather than fixing the system to one screen width.
The long base connection member was designed to telescope.
This gives the system a practical way to respond when the LED wall width changes.
Instead of manufacturing a completely different base simply because the screen becomes wider or narrower, the connection distance can be adjusted within the intended configuration of the component.
This directly addressed one of the customer's original requirements:
Different screen widths should not automatically require a new set of support materials.
The idea reflects a broader principle we use in modular temporary structures: when possible, identify which dimensions actually need to change and concentrate the adjustment there rather than redesigning every component.
More background on this modular approach is available in Modular System Logic for Stage, Truss & Scaffold.
Telescopic adjustment solved the distance problem.
It did not solve the angle problem.
For that, the ends of the connecting members also needed rotational adjustment.
Suggested caption:
Real base connection detail. Each end connection can rotate through more than 90° according to the supplied design requirement, allowing neighboring base sections to change direction for different LED screen geometries.
According to the design requirement for this project, each endpoint of the connecting member can rotate through more than 90 degrees.
That is important because the adjustment is not limited to the center of the system.
The connection at each end can change direction.
So the same base concept can be arranged differently depending on the LED layout.
This is the part that allows the support geometry to move away from a straight line and follow a curved configuration.
The broader relationship between connection methods, interfaces and modular compatibility is discussed in our Connection & Material System.
The final design logic can be summarized very simply:
Customer requirement | Design response |
|---|---|
Flat LED screen | Base connections can be aligned into a straight arrangement |
Curved LED screen | Base connection points can rotate to follow the changing direction |
Different curve angles | Rotatable endpoints allow the angle between support positions to be adjusted |
Different screen widths | Telescopic base members allow spacing to be adjusted |
Avoid buying separate structural sets | The same adjustable base concept is reused across different configurations |
This table looks simple.
Getting to this point was the important part.
The solution did not come from adding more and more special components.
It came from identifying where variation actually needed to happen.
The design simulations make this much easier to understand than words alone.
Suggested caption:
Top view of a curved LED configuration. The adjustable base connections change direction as the screen geometry changes, allowing the rear supports to follow different sections of the curve.
In the curved configuration, the support positions are not parallel.
Their orientations change as the LED screen changes direction.
This is exactly why a fixed straight base arrangement would have limited the system.
The same support concept rearranged behind a flat LED wall. The adjustable base system can return to a substantially straight alignment instead of requiring a separate flat-screen support structure.
For a flat LED wall, the geometry changes again.
Now the support frames can be arranged along the rear of the screen in a substantially straight line.
The important point is that the customer does not need the design concept to become:
Curved LED structure + separate flat LED structure.
The objective was:
one adaptable support system with different configurations.
A fixed custom base could certainly be designed around one known LED curve.
But that would solve only today's geometry.
The customer's requirement was different.
The structure needed to remain useful when the screen changed.
That shifted the design priority from:
optimization for one fixed shape
to:
adaptability across multiple expected configurations.
This is particularly relevant for equipment that may be repeatedly assembled in different layouts.
Every dedicated component added for one configuration can also become another component that must be:
stored;
identified;
transported;
matched to the correct project;
replaced if lost or damaged.
The customer's requirement to use the same materials therefore was not merely about reducing the initial component count.
It influenced the entire design logic.
Actual fabricated adjustable base assembly. The physical component confirms how the telescopic member and rotating end connections were implemented beyond the design simulation.
This photograph is important to this Case Study.
The CAD and simulation images explain what we intended to solve.
The fabricated base shows that the adjustment concept was actually translated into a physical component.
That distinction matters.
A design drawing can demonstrate an idea.
A manufactured prototype demonstrates that the idea progressed into fabrication.
At the same time, the photos and drawings supplied for this case do not by themselves establish a certified load capacity or universal suitability for every LED wall.
That is a separate engineering question.
The final concept used a rear support-frame arrangement combined with an adjustable floor-base system.
Rather than describing every component here—that belongs more naturally in a DragonStructure Product breakdown—the Case Study can be reduced to one decision chain:
Customer needed both flat and curved LED support
↓
Customer wanted to reuse the same structural materials
↓
Curve angle could change
↓
Screen width could also change
↓
A fixed base would restrict reuse
↓
We identified the base as the main geometric adjustment point
↓
Telescopic members addressed changing distance
Rotating endpoints addressed changing direction
↓
The same basic support system could be rearranged for multiple LED configurations
That is the real story behind this structure.
The most transferable lesson from this project is not specifically about LED screens.
It is about modular structural design.
When a customer says:
"I need one system to work in several different configurations, but I don't want to keep buying additional components,"
the first reaction should not necessarily be to make every part adjustable.
A better question is:
Which part of the geometry is actually changing?
In this case there were two changing variables:
distance and angle.
Both could be addressed at the base.
That allowed the rest of the structural concept to remain much more consistent.
In other words:
Instead of making the whole structure variable, we made the critical connection variable.
That is the design idea worth carrying into other modular projects.
This Case Study is based on the customer's stated functional requirements, the supplied design simulations and the actual fabricated base shown in the photographs.
They support the design story:
flat and curved LED configurations were considered;
different screen geometries were part of the requirement;
the base uses telescopic adjustment;
the connection points provide rotational adjustment;
the design was developed to reduce the need for separate structural sets.
However, this Case Study should not be interpreted as a verified engineering statement that the structure can support any LED screen of any size, weight or curvature.
The materials supplied for this article do not include project-specific structural calculations, certified capacities or load verification.
For an actual project, factors such as LED cabinet dimensions, total screen geometry, equipment weight, support spacing, connection details and the complete structural arrangement need to be confirmed for the intended configuration.
That was one of the main requirements of this design. The base system was developed with adjustable spacing and rotational connections so the support arrangement could be reconfigured between flat and curved layouts.
The actual suitability for a specific LED wall still depends on its dimensions, weight, geometry and complete project configuration.
The design uses rotating connection points at the ends of the base connecting members. According to the supplied project design, each endpoint can rotate through more than 90°, allowing the direction between neighboring support positions to change.
The base connecting members use a telescopic adjustment concept, allowing the spacing between support positions to change instead of using one permanently fixed distance.
Not necessarily. The purpose of this project was specifically to reduce that problem by concentrating the geometric adjustment in the base system.
However, this should not be interpreted to mean that one configuration is automatically suitable for every possible screen. The LED dimensions, weight, curve geometry and project requirements still need to be checked.
At minimum, we would want:
LED cabinet dimensions;
complete screen width and height;
flat or curved configuration;
required curve/radius or layout drawing where applicable;
LED screen weight and relevant equipment information;
installation environment;
drawings or photos of the LED system;
any existing support equipment the customer wants to reuse.
This page explains why this adjustable LED support concept was developed.
