Ring Clip Assembly for Compact Torque Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions face challenges in providing high torque or linear force resistance in compact packages with predictable and repeatable movement, which is complex to assemble and construct, especially in small sizes.
Innovation Solution
The ring clip friction device integrates a ring clip assembly with interlocking gear teeth or frictional elements, allowing for smooth linear force resistance by using a shaft with ring clips that flex radially to provide consistent torque or force profiles, adjustable by varying the number of ring clips, and capable of asymmetrical torque for balanced systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a friction clip hinge with gears is used to provide high torque resistance, then torque or linear force resistance is improved, but device complexity and package size increase
Solution Approach 1:
The patent combines the friction clip hinge and gear functions into a single integrated ring clip assembly. The ring clips themselves provide both the friction resistance and the gear-like transmission elements, eliminating the need for separate gear components and reducing overall assembly complexity while maintaining high torque resistance capability
Solution Approach 2:
The ring clip assembly serves multiple functions simultaneously: it provides friction-based torque resistance, acts as a gear transmission element through its interlocking teeth, and enables smooth predictable movement. This multi-functionality reduces the number of separate components needed and simplifies the overall device structure
2Force
If a friction clip hinge with gears is used to provide high torque resistance, then torque or linear force resistance is improved, but package size increases
Solution Approach 1:
By merging the friction clip and gear functions into a single ring clip component, the patent achieves high torque resistance in a compact form factor. The ring clips are mounted directly on a shaft and engage with transmission elements, eliminating the need for separate gear housings and reducing overall package volume
Solution Approach 2:
The ring clips are nested on the shaft in a compact arrangement, with multiple clips stacked along the shaft length. This nested configuration allows the torque resistance function to be achieved within a small radial envelope, minimizing the overall package size while maintaining high torque capability
3Reliability
If ring clips are used to provide smooth predictable movement, then movement predictability is improved, but manufacturing complexity increases
Solution Approach 1:
The patent uses multiple discrete ring clips stacked on the shaft, where each clip is a simple, easily manufactured component. This segmentation allows for straightforward manufacturing of individual clips and simple assembly by stacking them on the shaft, reducing overall manufacturing complexity while achieving smooth predictable movement through the combined action of multiple clips
Solution Approach 2:
The patent achieves smooth predictable movement by varying parameters such as the number of ring clips, their spacing along the shaft, and their engagement geometry with transmission elements. These parameter adjustments allow optimization of movement characteristics without complicating the basic clip design or assembly process

AI summary
One aspect is ring clip assembly including at least one ring clip having a ring portion surrounding an arm, the arm configured to define an aperture. The ring portion and the arm is separated thereby defining a slot between them. A shaft extends through the aperture in an interference fit, the arm configured to radially flex without contact from the ring portion. The ring portion has transmission elements on its outer perimeter configured to transmit movement to another member.
