Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple non-interchangeable through axle specifications are produced to fit different frame dropouts, then compatibility with various bicycle frames is improved, but production costs increase and user selection becomes more difficult
Solution Approach 1:
The through axle is designed with a universal conical interface structure that can accommodate multiple frame dropout specifications. The conical interface with specific angle range (30°-60°) allows the same axle design to fit different frame types, eliminating the need for multiple specialized axle specifications while maintaining compatibility across various bicycle frames.
Solution Approach 2:
The patent utilizes parameter variation in the conical interface angle (providing a range of 30°-60°) to achieve adaptability across different frame specifications. By designing the conical interface within this angle range, the through axle can interface with multiple frame dropout types without requiring completely different axle designs, thus reducing the number of specifications while maintaining versatility.
2Adaptability or versatility
If multiple non-interchangeable through axle specifications are produced, then compatibility with different frame dropouts is improved, but production costs increase
Solution Approach 1:
The through axle employs a universal conical interface design that serves multiple frame specifications simultaneously. This single design approach eliminates the need to manufacture multiple different axle types, thereby reducing tooling costs, inventory complexity, and production expenses while maintaining broad compatibility with various frame dropout standards.
Solution Approach 2:
The patent merges multiple frame specification requirements into a single conical interface design. By combining the functional requirements of different frame types into one standardized conical interface, the manufacturer can produce a single through axle model that satisfies multiple specifications, thereby consolidating production processes and reducing overall manufacturing costs.
3Adaptability or versatility
If multiple non-interchangeable through axle specifications are produced, then compatibility with different frame dropouts is improved, but user identification and selection becomes more difficult
Solution Approach 1:
The universal conical interface design means users only need to purchase one type of through axle to fit their frame, regardless of the specific frame specification. This eliminates the confusion of selecting from multiple non-interchangeable axle types, as the standardized conical interface ensures broad compatibility, thereby simplifying the user selection process to a single product choice.
