Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spring assembly connection designs are not cost-effective or easy to manufacture and install, especially when subjected to high loads, and do not allow for versatile arrangements of tension springs.
Innovation Solution
A spring assembly comprising multiple tension spring elements connected via a common holding element and connecting piece, with contour formations and optional end pieces for secure, non-positive, and positive connections, allowing for durable and load-safe configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If individual tension spring elements are used to assemble spring assemblies, then manufacturing cost is reduced and space requirements are minimized, but the connection reliability under high loads deteriorates
Solution Approach 1:
Multiple individual tension spring elements are merged into a single spring assembly through a common retaining element that connects all spring ends simultaneously. This combining approach maintains the cost and space advantages of individual springs while achieving reliable collective connection under high loads through the unified retaining structure.
Solution Approach 2:
The retaining element is designed with segmented connection points that individually engage with each tension spring element. This segmentation allows each spring to be independently secured while contributing to the overall assembly strength, maintaining both manufacturability and connection reliability.
2Reliability
If a common retaining element is used to connect multiple tension spring elements, then connection reliability is improved, but device complexity increases
Solution Approach 1:
The common retaining element serves multiple functions simultaneously: it connects multiple tension spring elements, distributes load across all connections, provides structural support for the assembly, and enables easy installation through a single component design. This multi-functionality improves reliability without proportionally increasing complexity.
3Reliability
If additional connecting elements are attached to the retaining element, then connection security is improved, but manufacturing cost increases
Solution Approach 1:
The retaining element and connecting elements are designed as an integrated assembly where multiple connecting elements are attached to the single retaining element. This merging approach secures multiple tension springs simultaneously, improving connection security while reducing the total number of separate components and assembly steps compared to individual connections.
