Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If LED chips are integrated onto the PCB, then the light board structure is simplified, but maintenance and replacement of faulty diodes becomes inconvenient
Solution Approach 1:
The light board is divided into modular units: the PCB contains circuitry and mounting holes, while LED chips are mounted on removable supports that can be individually accessed through backside openings. This segmentation allows the overall structure to remain simple while enabling easy maintenance of individual components.
Solution Approach 2:
Faulty LED chips are extracted from the PCB by accessing them through backside openings. The supports holding the LED chips can be removed from the PCB, allowing faulty chips to be taken out and replaced without disturbing the overall board structure or requiring front-side access.
2Stability of the object's composition
If LED chips are fixed on the PCB, then the light board structure is stable, but color changing and unit replacement becomes inflexible
Solution Approach 1:
The system transitions from a static, permanently fixed configuration to a dynamic one where LED chip supports can be easily removed and replaced. The backside openings and corresponding mounting holes enable the supports to be inserted and secured in a stable manner, yet also allow for easy removal and replacement of different colored LED chips to change display patterns.
3Ease of operation
If LED chips are accessible from the front side, then maintenance is straightforward, but the light board design becomes less flexible for various applications
Solution Approach 1:
Instead of accessing LED chips from the front side where light is emitted, the design inverts the access approach by providing openings on the backside of the PCB. This allows maintenance personnel to access and replace LED chips from the rear, maintaining ease of operation while preserving the aesthetic and functional integrity of the front-side display and enabling greater design flexibility.
