Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional lid locking devices with multiple components (brackets, webs, springs) are used, then the lid can be held in open position, but the device complexity increases and manufacturing time increases
Solution Approach 1:
The patent merges the locking element and pivot bracket into a single integrated component. The locking element is formed as one piece with the pivot bracket, eliminating the need for separate bracket webs, hinges, and locking springs found in traditional designs. This integration reduces the number of parts while maintaining the locking function through the elastic deformation of the integrated structure.
Solution Approach 2:
The patent extracts and eliminates unnecessary intermediate components (bracket webs, hinges, locking springs) from the traditional multi-component system. By removing these separate elements and retaining only the essential locking function, the design achieves simplicity while maintaining reliability through the elastic deformation mechanism of the integrated pivot bracket.
2Reliability
If traditional lid locking devices with multiple components are used, then the lid can be locked, but the manufacturing time increases due to assembly requirements
Solution Approach 1:
The locking element and pivot bracket are manufactured as a single integrated component, eliminating the need for separate assembly steps for connecting brackets, webs, and springs. This integration directly reduces assembly time while maintaining locking reliability through the built-in elastic deformation mechanism.
3Reliability
If traditional lid locking devices with multiple components are used, then the lid can be held open, but the susceptibility to wear increases
Solution Approach 1:
By integrating the locking element and pivot bracket into one component, the patent eliminates the interfaces between separate parts where wear would occur. The single integrated structure has fewer contact surfaces and no separate moving parts that would generate wear, thereby reducing susceptibility to harmful factors while maintaining holding force.
4Device complexity
If the pivot bracket is designed to undergo elastic deformation, then the locking mechanism becomes simpler, but the manufacturing precision requirements increase
Solution Approach 1:
The patent changes the physical state of the pivot bracket from rigid to elastically deformable. This parameter change allows the single integrated component to accommodate variations in manufacturing precision through its inherent flexibility, absorbing dimensional tolerances and reducing the stringency of precision requirements while maintaining the locking function.
