Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws are used to hold the control printed circuit board, then the board is securely fixed, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The fixing mechanism is segmented into modular components: the holder member with through holes and the control printed circuit board with retaining protrusions. This segmentation allows for simplified assembly where the protrusions simply insert into the through holes without requiring complex screw fastening operations, thereby reducing assembly complexity while maintaining secure fixation.
Solution Approach 2:
The holder member acts as an intermediary component between the heat dissipation plate and the control printed circuit board. It provides the through holes that receive the retaining protrusions, serving as a mediator that enables simple yet effective mechanical coupling without direct screw-fastening between the main components, thus simplifying the overall assembly process.
2Reliability
If tapes are used to hold the control printed circuit board, then the board is secured during transportation, but manufacturing costs increase
Solution Approach 1:
The control printed circuit board and holder member are designed to be self-fixing through the retaining protrusions and through holes mechanism. The structure itself provides the fixation function without requiring external materials like tapes, thereby reducing manufacturing costs while maintaining stability during transportation and assembly.
3Ease of manufacture
If the control printed circuit board is loosely held, then assembly is simple, but shaking occurs during transportation causing damage and noise
Solution Approach 1:
The fixing mechanism is segmented into modular components: the holder member with through holes and the control printed circuit board with retaining protrusions. This segmentation allows for simplified assembly where the protrusions simply insert into the through holes without requiring complex screw fastening operations, thereby reducing assembly complexity while maintaining secure fixation.
Solution Approach 2:
The retaining protrusions have an asymmetric design that provides directional stability within the through holes. This asymmetric geometry ensures that the control printed circuit board is held firmly in a specific orientation, preventing shaking and movement during transportation while keeping the assembly process simple.

AI summary
A display apparatus is disclosed that includes a display panel having front and rear surfaces; a heat dissipation plate having front and rear surfaces and the rear surface of the heat dissipation plate is on the rear surface of the display panel; a source printed circuit board on the rear surface of the heat dissipation plate, and connected to the display panel; a control printed circuit board on the rear surface of the heat dissipation plate and comprising a retaining protrusion that protrudes towards the rear surface of the display panel; and a holder member between the heat dissipation plate and the control printed circuit board and holding the control printed circuit board in the heat dissipation plate. The control printed circuit board is stably held and thus expected to have effects on reducing shaking during logistics transportation and simplifying a manufacturing process.
