Spring Clip Retainer for Safe Secateur Blade Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cutting tools such as secateurs pose a safety hazard during storage due to freely rotating blades that can be exposed, and existing solutions for keeping the blades closed during storage are cumbersome to use.
Innovation Solution
A cutting tool with a retaining means, such as a resilient retaining member or clip, that is biased towards an open position and can be attached to the shear parts, ensuring safe storage without interfering with operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If bands are wrapped around the cutting tool to keep blades closed during storage, then safety hazard is reduced, but ease of operation deteriorates due to difficult and cumbersome removal before use
Solution Approach 1:
The retaining means is designed as a resilient, movable component that can dynamically transition between engaged and disengaged states. It is biased towards an open position by a spring means, allowing it to automatically disengage when force is applied during use, eliminating the need for manual removal of static bands
Solution Approach 2:
The retaining means automatically performs the function of keeping blades closed during storage without requiring user intervention. The spring bias ensures it returns to the engaged position after use, and the resilient design allows it to self-adjust during operation, making the system self-servicing
2Object-affected harmful factors
If a retaining means is added to keep blades closed during storage, then safety hazard is reduced, but device complexity increases
Solution Approach 1:
The retaining means is segmented into distinct functional components: the resilient body with engagement features, the spring means for biasing, and the connection to the first shear part. This segmentation allows each component to perform its specific function independently while maintaining overall simplicity
Solution Approach 2:
The retaining means utilizes resilient material properties and spring bias to create a dynamic, automatic system rather than a static mechanical linkage. This reduces the number of additional components needed compared to traditional locking mechanisms

Function Achieved in This Case
The retaining means allows for safe storage of cutting tools by keeping blades closed without requiring cumbersome wrapping or unwrapping, enhancing user safety and convenience.
Implementation Method 1
a spring means configured for pushing a part of the second shear part towards the retaining means
Implementation Method 2
the retaining means is biased towards an open position in which the retaining means does not engage the second shear part

AI summary
A cutting tool 1 comprises a first shear part 2, a second shear part 3 rotatably connected to the first shear part 2 and a retaining means 10 movably connected to the first shear part 2. The cutting tool has a storage configuration in which the retaining means 10 engages the second shear part 3. The retaining means 10 is biased towards an open position in which the retaining means 10 does not engage the second shear part 2.
