Clamping Collar Spring Clip for Angular Misalignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing clamping systems with polygonal threaded nuts and screws face increased operating forces due to radius reduction when the screw is tightened, and complex, expensive mounting solutions are required to manage the angular position between the nut and screw.
Innovation Solution
A U-shaped spring clip with legs and retaining tabs is used to securely hold the threaded nut against rotation, allowing for play-free mounting and flexible angle compensation, enabling easier assembly and higher torque absorption without additional components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the threaded nut is rigidly fixed to the clamping element, then mounting precision is improved, but device complexity and cost increase due to additional components
Solution Approach 1:
The spring clip serves itself by using its elastic deformation to automatically position and secure the threaded nut. The clip's resilience allows it to self-adjust during assembly, eliminating the need for separate positioning mechanisms or additional fastening components.
Solution Approach 2:
The spring clip changes its physical state from a flexible assembly aid to a rigid positioning structure once deformed and secured to the clamping element. This parameter change allows the same component to provide both assembly flexibility and final mounting precision.
2Ease of manufacture
If the threaded nut is held in a spring clip, then ease of assembly is improved, but mounting precision may worsen due to potential play
Solution Approach 1:
The spring clip transitions from a dynamic, flexible state during assembly to a static, rigid state during operation. The elastic deformation required for assembly temporarily allows movement, but once secured, the clip maintains a fixed position that ensures precise mounting of the threaded nut.
3Force
If the clamping screw is tightened, then clamping force is improved, but operating force increases due to angular position change
Solution Approach 1:
The spring clip acts as an intermediary between the threaded nut and the clamping element, absorbing angular misalignment through its elastic deformation. This mediator allows the nut and screw to maintain optimal angular positioning during tightening, reducing the operating force required while maintaining effective clamping force.
