Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If hot riveting connection is used to fix the plastic bracket to the reinforcing plate, then the connection strength is improved, but the ease of disassembly deteriorates
Solution Approach 1:
The circuit board is divided into a wiring portion and a mounting portion, with the mounting portion being detachably mounted on the mounting bracket. This segmentation allows the wiring portion to remain permanently connected while the mounting portion can be easily removed for maintenance, resolving the contradiction between connection strength and ease of disassembly.
Solution Approach 2:
The mounting portion is designed with dynamic mounting characteristics, allowing it to be detachably mounted on the mounting bracket. This dynamic design enables the structure to transition between fixed and removable states, providing both strong connection during operation and easy disassembly when maintenance is needed.
2Stability of the object's composition
If hot riveting connection is used to fix the plastic bracket to the reinforcing plate, then the structural stability is improved, but the ease of repair deteriorates
Solution Approach 1:
By segmenting the circuit board into wiring portion and mounting portion, the invention maintains structural stability through the permanently fixed wiring portion while enabling easy repair through the detachable mounting portion. This allows damaged components to be replaced without affecting the overall structural integrity.
Solution Approach 2:
The mounting portion is extracted as a separate detachable component from the circuit board, allowing it to be removed and replaced independently. This extraction principle maintains the stability of the main structure while significantly improving ease of repair for the mounting portion and associated components.
3Reliability
If the collection assembly is made difficult to disassemble, then the reliability is improved, but the productivity deteriorates
Solution Approach 1:
The segmentation of the circuit board into wiring portion and mounting portion allows the invention to maintain reliability by keeping the wiring portion permanently connected while improving productivity by enabling quick removal and replacement of the mounting portion during maintenance operations.
Solution Approach 2:
The dynamic mounting design of the mounting portion allows it to be securely fixed during normal operation (maintaining reliability) while enabling rapid disassembly and reassembly during maintenance (improving productivity). This dynamic characteristic resolves the contradiction between reliability and maintenance efficiency.
