Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional LED display screens are used, then the structure is stable and fixed, but the screen cannot be folded, extended, or moved, resulting in poor universality and inconvenience in usage
Solution Approach 1:
The LED display screen is divided into multiple independent modules, each containing an FPC flexible circuit board with LED lamps, control circuits, and power lines. These modules can be separately manufactured, folded, and spliced together through interface circuits at the ends of FPC, enabling both flexibility and structural integrity. The segmentation allows the screen to be extended or contracted by adding or removing modules while maintaining stability through standardized connection interfaces.
Solution Approach 2:
The patent employs FPC (Flexible Printed Circuit) boards as the substrate for mounting LED lamps and control circuits. The FPC material itself is flexible and can be bent or folded without damage, replacing traditional rigid PCB boards. This flexible substrate enables the entire LED screen module to be bent, folded, or rolled while maintaining electrical connectivity, directly resolving the contradiction between flexibility and structural stability.
2Ease of operation
If LED screens are transported or stored as a whole piece, then the structure remains intact, but it results in much inconvenience and cannot be easily moved or stored
Solution Approach 1:
The LED screen is segmented into multiple standardized modules that can be independently transported and stored. Each module contains complete functional elements (LED lamps, control circuits, power lines, and interface circuits), allowing them to be handled separately. This segmentation dramatically improves ease of transport and storage compared to moving a large fixed screen as one piece, while the standardized interfaces ensure simple assembly without complex procedures.
Solution Approach 2:
The modules are designed with universal interface circuits at both ends of the FPC, allowing any module to be spliced with any other module in various configurations. This universal design enables the same module to be used in different positions and arrangements, simplifying both transport (all modules are identical and interchangeable) and assembly (any module can connect to any other through standardized interfaces).
3Adaptability or versatility
If LED screens are made with fixed length, then the manufacturing process is simple, but the screen cannot be extended in length as needed, resulting in poor universality
Solution Approach 1:
The LED screen is manufactured as multiple identical modules of fixed length, each with standardized interface circuits. During installation, these modules are spliced together in series to achieve the desired total length. This approach maintains the simplicity of manufacturing individual modules while providing extensibility through modular assembly, resolving the contradiction between fixed-length manufacturing simplicity and length adaptability.
Solution Approach 2:
The LED screen system transitions from a fixed-length design to a dynamic, adjustable length configuration through modular splicing. The interface circuits on FPC enable modules to be connected or disconnected dynamically based on installation requirements, allowing the screen length to be adjusted without remanufacturing. This dynamic approach maintains manufacturing simplicity by producing standardized modules while achieving length extensibility through flexible assembly.
