Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If rigid connection is used between first circuit board and frame, then structural stability is improved, but alignment flexibility deteriorates causing connection terminal misalignment
Solution Approach 1:
The first circuit board is designed to be movable relative to the display substrate through elastic components (springs), transforming the rigid static connection into a dynamic adjustable connection. This allows the circuit board to be positioned accurately during assembly while maintaining structural stability through the elastic support.
Solution Approach 2:
The connection system is segmented into multiple independent components: display substrate, frame, elastic components, and first circuit board. This segmentation allows independent optimization of each component's function, enabling the circuit board to move independently for alignment while the frame maintains overall structural stability.
2Manufacturing precision
If manual alignment method is used, then assembly precision can be achieved, but assembly time increases
Solution Approach 1:
The elastic components (springs) enable the first circuit board to self-adjust its position during assembly. The movable design allows the board to automatically align with connection terminals through elastic deformation, eliminating the need for complex manual alignment operations while ensuring precise connection.
Solution Approach 2:
The system changes the positional parameter of the first circuit board from fixed to variable through elastic components. This parameter change enables the board to adjust its position dynamically during assembly, achieving precise alignment through elastic deformation rather than manual intervention.
3Manufacturing precision
If first circuit board is made movable, then alignment accuracy is improved, but structural stability deteriorates
Solution Approach 1:
The first circuit board is designed as a movable component connected through elastic springs, allowing it to adjust position for accurate alignment. The elastic connection maintains structural stability by providing controlled flexibility rather than rigid fixation, enabling both movement and stability.
Solution Approach 2:
The connection stiffness parameter is changed from rigid (infinite stiffness) to elastic (finite stiffness). This parameter change allows the first circuit board to move for alignment while the elastic components maintain overall structural stability through controlled deformation.
