Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If connecting rods are used in the braking system, then force transmission is achieved, but the system becomes bulky and loses compactness
Solution Approach 1:
The invention extracts and eliminates the connecting rods from the braking system. By removing these unnecessary intermediate components, the system achieves better compactness while maintaining force transmission capability through the connector's rigid structure and strategic anchor point placement.
Solution Approach 2:
The invention merges the functions of force transmission and structural support into the connector itself. The connector with its two vertical rods and attachment head integrates multiple functions that were previously distributed across separate components, eliminating the need for dedicated connecting rods.
2Volume of moving object
If the braking system is made compact without connecting rods, then compactness is improved, but force transmission efficiency may be compromised
Solution Approach 1:
The connector is pre-configured with two vertical rods and an attachment head that are optimally positioned to handle force transmission from the outset. This preliminary structural arrangement ensures that when the braking system operates, forces are efficiently transmitted through the rigid connector structure without requiring additional transmitting components.
Solution Approach 2:
The invention utilizes the vertical dimension by implementing two vertical rods in the connector. This vertical arrangement provides robust force transmission paths in multiple directions, compensating for the reduced horizontal space available in a compact system design.
3Device complexity
If a single anchor point is used, then the system structure is simplified, but force transmission rigidity may be reduced
Solution Approach 1:
The connector with its two vertical rods and attachment head serves multiple functions simultaneously: it provides structural support, transmits forces in multiple directions, and maintains rigidity. This multi-functional design allows a single anchor point configuration to achieve both simplification and rigidity.
Solution Approach 2:
The attachment head of the connector is designed with a spherical or rounded geometry that allows for optimal force distribution in multiple directions. This curved design enables the single anchor point to effectively transmit forces from various angles, maintaining rigidity while simplifying the overall structure.
