Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If adhesive is applied directly on LED beads for mounting on transparent glass, then the display can be fixed, but the display quality degrades and disassembly for repair becomes difficult
Solution Approach 1:
The patent divides the mounting structure into separate components: the LED bead, the PCB board with through-hole, and the transparent glass substrate. The connecting post extends through the PCB from the rear side, allowing the LED bead to be mounted on the front side while the post protrudes through the rear side for separate adhesive application and glass bonding. This segmentation enables independent optimization of LED mounting and glass bonding processes.
Solution Approach 2:
The connecting post acts as an intermediary element between the LED bead and the transparent glass. It provides a dedicated adhesive application surface that mediates the bonding process, preventing direct contact between adhesive and LED bead while still achieving strong mounting strength through the post-to-glass adhesive bond.
2Strength
If adhesive is applied directly on LED beads, then the display can be fixed to glass, but display quality degrades due to adhesive contact with LED beads
Solution Approach 1:
The patent extracts the adhesive application function from the LED bead surface and relocates it to the connecting post. The adhesive is applied only on the connecting post that extends through the PCB board, completely separating the adhesive from direct contact with the LED bead. This extraction eliminates the quality degradation caused by adhesive contamination while maintaining bonding strength through the post-glass interface.
3Ease of repair
If connecting posts extend through PCB board, then disassembly becomes easy, but structural complexity increases
Solution Approach 1:
The connecting post serves multiple functions simultaneously: it provides mechanical support for the LED bead, acts as an adhesive application substrate, extends through the PCB board to enable disassembly, and bonds to the transparent glass for mounting. This multi-functionality reduces the need for separate components, thereby minimizing structural complexity while achieving ease of maintenance.
