Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional fasteners are used to secure the adapter to the servo motor splined shaft, then the connection reliability is improved, but the device complexity increases
Solution Approach 1:
The patent merges the fastening function into the coupler body itself by incorporating adjustable clamping portions with deformation zones that directly engage the auxiliary shaft. This eliminates the need for separate additional fasteners, reducing device complexity while maintaining secure connection through the integrated clamping mechanism.
Solution Approach 2:
The coupler's adjustable clamping portions serve their own fastening function by deforming the bore dimensions to directly clamp the auxiliary shaft. The structure is self-sufficient in securing the shaft without requiring external fasteners, thereby simplifying the overall device while ensuring reliable connection.
2Adaptability or versatility
If the coupler design is made adaptable to different servo motor configurations, then the adaptability is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The patent incorporates adjustable clamping portions that can deform the bore dimensions dynamically to accommodate different auxiliary shaft sizes and configurations. This adjustability allows the same coupler design to adapt to various servo motor types without requiring precision manufacturing for each specific configuration, as the deformation capability provides the necessary flexibility.
Solution Approach 2:
The coupler utilizes parameter changes in the bore dimensions through the deformation of the adjustable clamping portions. By changing the dimensional parameters of the bore to match different shaft sizes, the coupler achieves broad adaptability while maintaining standard manufacturing specifications, avoiding the need for high-precision custom manufacturing for each application.
3Ease of operation
If the coupler uses adjustable clamping portions to deform bore dimensions, then the ease of operation is improved, but the manufacturing complexity increases
Solution Approach 1:
The coupler is segmented into distinct functional zones, including adjustable clamping portions with deformation zones separated from the main body. This segmentation allows the complex deformation mechanism to be localized and simplified in manufacturing, while providing easy operation through the adjustable clamping action on the auxiliary shaft.

AI summary
A coupler for coupling an output shaft of a servo to an auxiliary shaft, comprises an coupler body having a longitudinal axis extending from a first end to a second end. The coupler body comprises a first bore, configured to accept a portion of the auxiliary shaft, centered on the longitudinal axis and extending into the first end a first distance. The coupler also comprises a second bore centered on the longitudinal axis and extending into the second end a second distance. The coupler also comprises a first fastener disposed proximate the first end, wherein adjusting the first fastener deforms a cross sectional dimension of the first bore. The coupler also comprises a second fastener disposed proximate the second end, wherein adjusting the second fastener deforms a cross sectional dimension of the second bore. An inner surface of the second bore has a female spline configuration to accept and engage a portion of the output shaft of the servo.
