Bottle Cell Holder Joints for Tolerance-Driven Stress Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bottle cell carriers in bottle cleaning machines experience high stresses and wear due to manufacturing tolerances and changing loads, leading to hairline cracks and breakage.
Innovation Solution
A bottle cell carrier design with a mechanical connecting device allowing relative movement between the side parts and roller chains, incorporating lightweight cutouts and universal or ball joints to decouple force transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid two-bolt fastening is used between the roller chain and bottle cell carrier, then the connection strength is improved, but the stress concentration and risk of breakage increase due to manufacturing tolerances and changing loads
Solution Approach 1:
The patent replaces the rigid two-bolt fastening with a dynamic connection system that includes at least one universal joint and at least one ball joint. These joints enable the bottle cell carrier to move relative to the roller chain, absorbing stresses caused by manufacturing tolerances and changing loads during operation, thereby preventing stress concentration and breakage while maintaining connection strength
2Force
If a rigid connection is used between the side parts and roller chain, then the force transmission is improved, but the wear and stress on the bottle cell carrier increase
Solution Approach 1:
The patent introduces universal joints and ball joints as intermediary elements between the roller chain and bottle cell carrier. These intermediaries enable force transmission while accommodating relative movements and reducing stress concentration, thereby decreasing wear and stress on the bottle cell carrier during operation
3Ease of manufacture
If manufacturing tolerances are present in the chain guide and bottle cell carrier, then the ease of manufacture is improved, but the stress distribution becomes uneven leading to high stresses
Solution Approach 1:
The patent employs universal joints and ball joints that provide dynamic adjustment capabilities, allowing the system to compensate for manufacturing tolerances in the chain guide and bottle cell carrier. This dynamic connection ensures even stress distribution by accommodating dimensional variations while maintaining proper force transmission during operation
