Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If the spring element has a constantly increasing distance from the abutment element in the initial state, then high spring forces and long spring paths are achieved, but the device complexity increases due to the curved abutment surface configuration
Solution Approach 1:
The abutment surface is configured with a curved configuration, specifically a circular segment shape, which allows the spring element to achieve optimal elastic deformation throughout its deflection path. This curved geometry enables the spring element to maintain consistent contact and distribute forces evenly, achieving high spring forces and long spring paths without requiring additional complex components.
2Length of moving object
If the spring element is able to abut against the abutment element for reaching a maximally deflected state, then long spring paths are achieved, but the manufacturing precision requirements increase for the curved abutment surface
Solution Approach 1:
The curved abutment surface configured as a circular segment provides a geometrically precise contact path that guides the spring element through its deflection. This standard curved geometry can be manufactured with conventional precision methods, allowing the spring element to achieve its full deflection path without requiring excessive manufacturing tolerances.
3Reliability
If the spring element has an increasing distance configuration, then optimal elastic deformation is achieved, but the ease of manufacture decreases due to the non-linear geometry
Solution Approach 1:
The circular segment-shaped abutment surface provides a standardized curved geometry that can be manufactured using conventional forming processes. This standard curved shape allows for reliable optimal elastic deformation of the spring element while remaining compatible with standard manufacturing methods, avoiding the need for complex custom tooling or processes.
