Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing chain tensioning devices are prone to unintentional release due to complex operation and high risk of operating errors, especially under shocks and vibrations, as they rely on securing chains that can be difficult to manage.
Innovation Solution
A tensioning device with a securing element that forms a positive, rigid coupling between the coupling element and the spindle body, allowing for a simple movement to secure the device, reducing the complexity of assembly and the risk of errors, by using non-circularly symmetric retaining profiles and magnetic connections for enhanced stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a securing chain is used to prevent unintentional release, then the coupling elements are secured against unscrewing, but the operation becomes complicated and the risk of operating errors increases
Solution Approach 1:
The invention extracts the securing function from the complex chain-based system and integrates it directly into the coupling element through the securing element (5) with retaining profiles (5f). This integration eliminates the need for separate securing chains while maintaining security against unintentional release, thereby simplifying operation and reducing operating errors.
Solution Approach 2:
The securing element (5) combines the coupling function and securing function into a single integrated component. The retaining profiles (5f) on the coupling element work together with the securing element to prevent unscrewing, merging what were previously separate functions (coupling and securing) into one unified mechanism that is both secure and simple to operate.
2Reliability
If a securing chain is used to prevent unintentional release, then the coupling elements are secured against unscrewing, but the device complexity increases
Solution Approach 1:
The invention removes the external securing chain from the system and extracts the securing function into the coupling element itself through the securing element (5) with retaining profiles (5f). This extraction eliminates unnecessary components and simplifies the overall device structure while maintaining security against unintentional release.
Solution Approach 2:
The coupling element is designed with multi-functionality, serving both as the coupling mechanism and the securing mechanism through its integrated retaining profiles (5f). This universal design eliminates the need for separate securing chains and other additional components, reducing device complexity while ensuring security against unintentional release.
3Reliability
If securing chains are used, then protection against unintentional release is provided, but the risk of operating errors remains high under shocks and vibrations
Solution Approach 1:
The securing element (5) with retaining profiles (5f) is designed to automatically engage and secure the coupling element without requiring manual manipulation of separate securing chains. This self-service mechanism reduces the risk of operating errors by eliminating complex manual securing operations that are prone to mistakes, especially under shocks and vibrations.
Solution Approach 2:
The invention extracts the securing function from the manual chain-based system and integrates it into the coupling element itself. This integration creates a more reliable system that is less susceptible to operating errors under adverse conditions such as shocks and vibrations, as the securing mechanism is now inherent to the coupling element rather than a separate manual operation.
