Reversible Pocket Clip Mounting for Portable Cutting Tools
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing folding knives with reversible clips suffer from rotation relative to the handle due to insufficient friction, leading to loss of clipping functionality and the need to produce separate right-handed and left-handed models, which is economically inefficient.
Innovation Solution
A portable cutting tool with a connector-receiving structure on the handle that includes multiple holes and engagement structures, allowing a pocket clip to be securely attached to either lateral surface of the handle through various configurations, including elastic and screw-based mechanisms, to prevent rotation and enable easy switching between right-handed and left-handed use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a reversible clip is secured to the knife handle by fastened screws, then the knife can be transformed between right-handed and left-handed states, but the clip is prone to rotation relative to the knife handle due to circular screw holes and insufficient friction
Solution Approach 1:
The patent replaces circular screw holes with non-circular engagement structures (such as rectangular or oval holes) that prevent rotational movement of the clip relative to the handle. This asymmetric geometry ensures the clip remains firmly positioned while still allowing reversal between right-handed and left-handed configurations, thus maintaining both reliability and adaptability.
Solution Approach 2:
The patent employs a dynamic securing mechanism where the clip can be easily inserted and removed from different engagement positions on the handle. The engagement structures are designed to allow quick transformation between right-handed and left-handed states while maintaining secure attachment during use, enabling flexible reconfiguration without compromising stability.
2Adaptability or versatility
If both right-handed and left-handed knives are produced to meet different user preferences, then all users can find their preferred carrying orientation, but it is not economical due to required production equipment and possible overstocking
Solution Approach 1:
The patent makes a single knife model universal by enabling the clip to be positioned on multiple sides of the handle through multiple engagement structures. This allows one knife design to serve both right-handed and left-handed users, eliminating the need to produce separate models and reducing manufacturing complexity and inventory requirements while maintaining full adaptability to different user preferences.
Solution Approach 2:
The patent divides the handle into multiple segments or surfaces with distinct engagement structures, allowing the clip to be independently positioned on different sides. This segmentation enables a single knife to function in multiple configurations without requiring separate production lines for right-handed and left-handed versions, simplifying manufacturing and reducing costs.

AI summary
A portable cutting tool with a pocket clip is provided. The portable cutting tool includes a blade structure and a handle structure. The handle structure includes a tail portion having thereon a first hole, a second hole and a third hole on a first lateral surface, a second lateral surface and a third lateral surface of the tail portion, respectively. The pocket clip includes a clip body and a securing member. A first segment of the clip body is selectively inserted into the first hole or the second hole and fixed through the securing member and a securing hole formed on the first segment of the clip body, thereby fixing the clip body to the first lateral surface or the second lateral surface of the tail portion to enable a second segment of the clip body located outside the handle structure to perform a clipping function.
