Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing coupling mechanisms are used, then secure engagement is achieved, but device complexity increases due to excessive components
Solution Approach 1:
The patent combines multiple coupling functions into a single integrated coupling member that includes both the first and second coupling members as part of one component. This merging reduces the total number of separate components while maintaining the secure engagement functionality through the coordinated movement of the integrated parts.
Solution Approach 2:
The coupling member is designed to perform multiple functions simultaneously: it provides secure engagement through the first coupling member, enables controlled movement through the second coupling member, and incorporates a bias member for automatic positioning. This multi-functionality reduces the need for separate dedicated components for each function.
2Ease of operation
If existing coupling mechanisms are used, then engagement functionality is achieved, but manufacturing cost increases due to excessive components
Solution Approach 1:
By merging the first and second coupling members into a single integrated component, the patent reduces the number of parts that need to be manufactured, stored, and assembled. This consolidation directly reduces manufacturing costs while preserving the complete engagement functionality through the integrated design.
3Ease of operation
If existing coupling mechanisms are used, then coupling functionality is achieved, but reliability decreases due to increased modes of failure
Solution Approach 1:
The integration of multiple coupling members into a single component reduces the total number of potential failure points. Fewer separate parts mean fewer interfaces where failures can occur, thereby improving overall reliability while maintaining the necessary coupling functionality.
Solution Approach 2:
The bias member is incorporated to preemptively counteract potential positioning issues or engagement problems by continuously applying a restoring force. This ensures the coupling member returns to its proper engaged position, preventing failures before they occur.
4Ease of operation
If existing coupling mechanisms are used, then engagement capability is achieved, but manufacturing complexity increases
Solution Approach 1:
The patent reduces manufacturing complexity by combining multiple coupling members into a single integrated component. This eliminates the need for separate manufacturing processes and assembly steps for each individual coupling member, simplifying the overall manufacturing workflow while maintaining engagement capability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The coupling mechanism effectively reduces the number of components and simplifies the functionality and manufacturing process, while ensuring secure engagement and disengagement of the shaving cartridge.
Implementation Method 1
the first coupling member may include a bias member being configured to bias the first coupling member toward the first coupling member first position
Implementation Method 2
the second coupling member may include a ramp extending from a root to an edge, the ramp being configured to contact the first coupling member when the second coupling member moves relative to the first coupling member between the second coupling member first position and the second coupling member second position
