Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bolt fastening or threading is used to connect supported object and supporting object, then reliability of support is improved, but tool requirement and operation complexity increase
Solution Approach 1:
The connection structure is divided into a mounting member and a connection member with distinct functional regions: positioning walls for alignment, fixation edges for securing, and a deforming end with snapping tab for attachment. This segmentation allows each component to perform its specific function efficiently, enabling tool-free operation while maintaining reliability.
Solution Approach 2:
The connection member features a self-service mechanism where the deforming end can be manually elastically deformed to release the snapping tab from the snapping slot, enabling tool-free detachment. The elastic deformation capability allows the connection to be established and released by hand pressure alone, eliminating the need for external tools.
2Strength
If bolt fastening or threading is used to connect supported object and supporting object, then connection strength is improved, but assembly time increases
Solution Approach 1:
The positioning walls and fixation edges are pre-configured in the mounting member to automatically guide and secure the connection member during insertion. This preliminary positioning action ensures proper alignment and engagement before the final snapping connection is made, enabling rapid assembly without time-consuming alignment adjustments.
Solution Approach 2:
The connection strength is maintained through the elastic deformation parameter of the deforming end. By utilizing material elasticity, the connection provides strong holding force during normal use while allowing easy release through deliberate manual deformation, achieving both strength and speed without requiring multiple fastening steps.
3Reliability
If traditional detachable structure is used for frequently detached components, then connection reliability is maintained, but operation convenience deteriorates
Solution Approach 1:
The deforming end is designed with dynamic elastic properties, allowing it to flexibly transition between locked and unlocked states. This dynamic characteristic enables frequent attachment and detachment operations to be performed quickly by hand pressure, making the connection as easy to operate as it is reliable to maintain.
