Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing traction mechanism drives face challenges in accommodating reinforcement panels due to manufacturing inaccuracies and tolerances, leading to structural damage and increased manufacturing complexity in guide and tensioning rails made from plastic.
Innovation Solution
A supporting body with a receiving groove featuring alternating delimiting elements and gaps allows for easier accommodation of reinforcement panels, reducing material and manufacturing costs while enhancing mechanical deformability and load capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the receiving groove is made large to facilitate insertion of the reinforcement panel, then the insertion ease is improved, but the reinforcement panel may vibrate or fall out of the receiving groove
Solution Approach 1:
The receiving groove is segmented into multiple sections by transverse spacing elements that create gaps between delimiting elements. This segmentation allows the reinforcement panel to be easily inserted while the spacing elements prevent excessive movement, vibration, or detachment of the panel during operation.
2Reliability
If the receiving groove is made narrow to secure the reinforcement panel, then the panel retention is improved, but the insertion of the reinforcement panel becomes difficult or impossible
Solution Approach 1:
The receiving groove is divided into multiple sections by transverse spacing elements, creating a segmented structure with gaps. This segmentation provides insertion clearance while maintaining retention through the spacing elements that limit panel movement.
Solution Approach 2:
The spacing elements provide dynamic adjustment capability, allowing the receiving groove to adapt to manufacturing tolerances and panel dimensions. The gaps enable the structure to flex and accommodate variations during insertion while maintaining secure retention during operation.
3Manufacturing precision
If multiple ribs are added to the receiving groove to compensate for manufacturing inaccuracies, then the manufacturing tolerance compensation is improved, but the manufacturing complexity increases
Solution Approach 1:
Instead of adding multiple ribs, the invention uses transverse spacing elements that segment the receiving groove into sections with gaps. This simpler segmented approach compensates for manufacturing inaccuracies by providing adjustment clearance without increasing structural complexity.
Solution Approach 2:
The invention extracts the essential function of tolerance compensation by removing material to create gaps between delimiting elements, rather than adding ribs. This extraction approach achieves tolerance compensation with reduced manufacturing complexity.
4Weight of moving object
If material is removed to create gaps between delimiting elements, then the weight is reduced, but the mechanical strength may be compromised
Solution Approach 1:
The receiving groove is segmented by spacing elements that create controlled gaps, removing minimal material while maintaining structural integrity. The segmented structure preserves mechanical strength by keeping delimiting elements intact and properly positioned.
Solution Approach 2:
Material is removed locally only where needed to create gaps between delimiting elements, rather than reducing material throughout the entire structure. This localized material removal minimizes impact on overall mechanical strength while achieving weight reduction.
