Multi-Cavity Fastening Sleeve for Hidden Hole Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inserting a fastener through a multi-cavity object, such as those in traction battery packs, is challenging due to the hidden receiving hole, making it difficult to ensure the fastener engages correctly.
Innovation Solution
A fastening assembly that includes a sleeve extending through a hole in a multi-cavity object, guiding a fastener to a receiving hole, with a lead-in taper facilitating insertion and ensuring engagement, and a method involving inserting a sleeve through a hole in the object and guiding a fastener to the receiving hole.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a fastener is inserted directly through a multi-cavity object, then the fastening process is simple, but it is difficult to ensure accurate engagement with the hidden receiving hole
Solution Approach 1:
A sleeve is introduced as an intermediary component between the fastener and the multi-cavity object. The sleeve extends through the cavities and provides a visible guide feature that facilitates accurate alignment and insertion of the fastener into the hidden receiving hole, thereby improving engagement accuracy without requiring complex positioning mechanisms
Solution Approach 2:
The sleeve is pre-installed through the multi-cavity object before fastener insertion. This preliminary action establishes the correct path and position for the fastener, ensuring that when the fastener is inserted, it automatically follows the sleeve's guidance to engage the receiving hole accurately
