Tolerance Compensation Assembly With Screw-Thread Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for compensating for tolerances between parts to be screwed together are complex and costly, with limited accuracy in maintaining the relative distance between parts.
Innovation Solution
A device with a holding device on one part and a compensation device that can move relative to the holding device, featuring an inner engagement structure for form-fit engagement with the connecting screw threads, allowing targeted force flow and reduced component count.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a device with multiple individual components is used for tolerance compensation, then the tolerance compensation function is achieved, but the device complexity and manufacturing costs increase
Solution Approach 1:
The patent combines multiple individual components into an integrated compensation device that includes a holding device and a compensation device as unified structures. The holding device integrates mounting features and positioning elements, while the compensation device integrates the compensation mechanism with engagement structures, reducing the total component count while maintaining tolerance compensation functionality
Solution Approach 2:
The compensation device is designed to perform multiple functions: it provides tolerance compensation, maintains relative positioning between parts, and enables force transmission through the connecting screw. The holding device serves both as a mounting structure and as a positioning reference, reducing the need for separate dedicated components for each function
2Device complexity
If support is provided solely via device components, then the device structure is simplified, but the accuracy of tolerance compensation is limited
Solution Approach 1:
The connecting screw serves as an intermediary element that bridges the compensation device and the parts to be assembled. It transmits forces and moments between the compensation device and the parts, enabling accurate tolerance compensation by allowing the compensation device to maintain precise relative positioning while supporting the assembly through the screw mechanism
Solution Approach 2:
The compensation device is designed with movable elements that can adjust during the assembly process. The compensation device can move relative to the holding device, allowing it to adapt to tolerance variations and maintain accurate positioning dynamically during assembly and operation
