Compensation Nut Fastener Assembly Torque Clip Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastener assemblies, particularly compensation nut assemblies, face issues with noise due to rattling and loose connections caused by gaps between components, and require labor-intensive welding for secure connections, with torque clips being prone to slipping and dislodging.
Innovation Solution
A compensation nut fastener assembly featuring a torque clip with securing members, including a fixing clip and offset tab, securely fixed within a nut channel to prevent rotation and dislodging, and eliminating the need for a separate O-ring by defining a minimum offset distance between nuts to prevent jamming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fasteners are welded to components to provide a secure connection, then a reliable connection is achieved, but the process is labor and time intensive, adding cost to manufacturing
Solution Approach 1:
The invention replaces the welding process (thermal/mechanical system) with a mechanical fastening system consisting of a fastener, torque clip, and nut assembly. This substitution eliminates the need for welding operations while providing equivalent or superior connection security through threaded engagement and mechanical retention features
Solution Approach 2:
The fastener assembly is designed to be self-installing without requiring external welding equipment or specialized operators. The threaded fastener automatically secures components through screwing action, and the torque clip with securing members self-anchors to the nut, eliminating labor-intensive welding processes
2Reliability
If a separate O-ring is used to prevent the top nut from jamming with the bottom nut, then jamming is prevented, but the device complexity increases
Solution Approach 1:
The anti-jamming function previously performed by a separate O-ring is merged into the torque clip structure itself. The body configuration and securing members of the torque clip create clearance and prevent direct contact between the top nut and bottom nut, eliminating the need for an additional O-ring component while maintaining jamming prevention
Solution Approach 2:
The torque clip is designed to perform multiple functions simultaneously: centering the fastener in the fastener-receiving channel, preventing torque application to the nut, anchoring securely to the nut via securing members, and preventing jamming between nuts. This multi-functionality eliminates the need for separate specialized components

AI summary
A compensation nut fastener assembly (100) may include a first nut (110) including a first channel, a second nut (112) including a second channel configured to receive a portion of the first nut, and a torque clip (300) including at least one securing member (304) radially extending from the shaft (306). The shaft (306) is securely fixed within the first channel. The securing member(s)(304) may include a fixing clip (322) that securely fixes the torque clip (300) to the first nut, and an offset tab (326) that defines a minimum offset distance between the first nut and the second nut.
