Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional snap hooks have limited functionality, requiring users to carry additional tools for tasks like tightening bolts or using a screwdriver, which increases burden for mountaineers and cyclists.
Innovation Solution
A versatile snap hook design incorporating a frame, gate, and pivotally connected screwdriver blade, allowing for engagement with different straps and providing a built-in screwdriver function without the need for an additional tool.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional snap hook is designed with a single function, then its structure remains simple, but its versatility is limited and users must carry additional tools
Solution Approach 1:
The patent combines a snap hook and a screwdriver blade into a single integrated tool. The screwdriver blade is pivotally connected to the frame of the snap hook, allowing both functions (hanging/ securing objects and screwdriving) to be merged in one device, thereby improving versatility without requiring users to carry separate tools
Solution Approach 2:
The snap hook is designed to perform multiple functions: it can hang and secure objects using its frame and gate mechanism, and it can also function as a screwdriver for tightening or loosening screws and bolts. The pivotal connection allows the screwdriver blade to be deployed when needed and stowed when not in use, enabling universal application in various scenarios
2Adaptability or versatility
If users carry additional tools like a screwdriver for tightening bolts, then all necessary functions are available, but the burden and weight increase
Solution Approach 1:
By merging the snap hook and screwdriver blade into one integrated tool, the total weight is reduced compared to carrying separate tools. The screwdriver blade is pivotally connected to the frame, allowing it to be stored within the snap hook structure, thereby eliminating the need for additional separate tool weight while maintaining full functional capability
Solution Approach 2:
The multi-functional design allows a single tool to replace multiple tools (snap hook plus screwdriver), reducing the total weight and burden on users while providing all necessary functions for both hanging/securing objects and screwdriving operations

AI summary
A snap hook includes a frame, a gate, and a screwdriver blade. The frame has a first hook portion and a second hook portion located on different sides. The gate has an abutting end abutting against an end of the first hook portion. The screwdriver blade is pivotally connected to the frame, and a working end is formed on an end of the screwdriver blade whereby the snap hook could be engaged with two objects through the first hook portion and the second hook portion. The gate blocks a side opening of the first hook portion, and therefore the object hanged in the first hook portion would not fall out accidentally. Furthermore, the screwdriver blade increases the added value of the snap hook.
