Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional braking devices are used, then braking function is achieved, but assembly complexity increases and requires special assembly operations
Solution Approach 1:
The patent combines the braking medium containment and the coupling mechanism into a single integrated component. The braking device comprises a first component, a second component, and a containment body that are assembled together to form a unified braking assembly, eliminating the need for separate assembly operations for introducing the braking medium.
Solution Approach 2:
The patent employs a nested structure where the first component is received within the containment body, and the second component is received within the first component. This nesting arrangement allows the braking medium to be contained within the nested components without requiring additional seals or complex assembly operations.
2Productivity
If traditional braking devices are used, then braking function is achieved, but mounting time and installation complexity increase
Solution Approach 1:
The braking medium is pre-contained within the nested components during manufacturing, eliminating the need for special assembly operations or devices during installation. The containment body is designed to hold the braking medium in place before installation, allowing for quick mounting without additional steps.
Solution Approach 2:
The elastically yielding material in the second component automatically seals and secures the braking medium within the nested structure during assembly. The material's elasticity provides self-sealing and self-retention functions, eliminating the need for additional sealing components or complex fastening operations.
3Ease of operation
If compact design is implemented, then mounting ease is improved, but structural simplicity may be compromised
Solution Approach 1:
The patent uses a nested arrangement where components are received within one another in a compact configuration. The first component is received within the containment body, and the second component is received within the first component, creating a space-efficient design that maintains structural clarity.
Solution Approach 2:
The second component is made of elastically yielding material, which allows it to deform and seal within the nested structure. This flexible material enables compact mounting while maintaining structural integrity and simplicity through its adaptive sealing capability.
