Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clamps, particularly releasable clamps, face challenges in accurately and precisely holding articles, often applying insufficient or excessive compressive forces, requiring specialist tools for operation, and having complex and slow repeated opening and closing processes.
Innovation Solution
A releasable clamp design featuring a set of jaws, spacers, and retaining members that allow for precise control of compressive forces without the need for specialist tools, enabling accurate and reproducible holding of articles in desired dispositions through a configurable mechanism that simplifies and accelerates opening and closing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional threaded fasteners or cams are used to apply compressive forces, then the clamp can hold articles, but the compressive forces may be insufficient or excessive and specialist tools are required for operation
Solution Approach 1:
The patent employs a spring mechanism that automatically adjusts compressive force parameters. The spring's elastic properties enable it to apply consistent, controlled force without requiring manual adjustment or specialist tools, resolving the contradiction between ease of operation and reliable force control
Solution Approach 2:
The spring-loaded mechanism is self-regulating, automatically maintaining appropriate compressive force on the article. The system serves itself by using the spring's inherent elastic recovery to maintain pressure, eliminating the need for external tools or complex adjustment mechanisms
2Productivity
If traditional releasable clamps are designed for repeated opening and closing, then they can be reused, but the process is relatively complex and slow
Solution Approach 1:
The clamp is divided into distinct functional segments: a jaw assembly, a spring mechanism, and a release mechanism. This segmentation allows each component to perform its specific function efficiently, enabling rapid opening and closing without requiring the entire mechanism to be complex
Solution Approach 2:
The spring mechanism provides dynamic, automatic operation. When the release mechanism is activated, the spring's stored energy rapidly drives the jaw open, and when closed, the spring automatically applies force. This dynamic behavior enables fast repeated operations without complex control systems
3Reliability
If traditional clamps apply compressive forces to hold articles, then they secure the articles, but the forces may be excessive resulting in damage to the articles
Solution Approach 1:
The spring mechanism acts as a cushioning element that limits maximum compressive force. The spring's elastic properties prevent the application of excessive force that could damage the article, while still providing sufficient holding pressure. This beforehand cushioning protects the article from harmful forces
Solution Approach 2:
The spring's elastic modulus and pre-compression can be designed to provide optimal holding force parameters. By carefully selecting these parameters, the clamp applies just enough force to secure the article accurately without exceeding damage thresholds
