Tie Plier with Integrated Cutting for One-Handed Steel Tie Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional stainless steel ties are difficult to operate with due to their smooth surface and thinness, leading to inadequate binding and potential damage to articles, and existing solutions require two-handed operation, which is inconvenient.
Innovation Solution
A tie plier design featuring a first support connected to a handle, a rotatable second support, elastic members for resetting, a feed head with a cutting groove, and a semi-cylindrical cutting bit, allowing one-handed operation and efficient binding and cutting of ties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional two-handed stainless steel tie bundling tool is used, then the cutting function is achieved, but the operation convenience deteriorates due to requiring both hands
Solution Approach 1:
The patent merges the cutting function into the main body structure of the tie bundling tool by integrating a cutting groove and cutting bit directly into the first support, eliminating the need for a separate cutting tool. This allows one-handed operation while maintaining both binding and cutting functions, resolving the contradiction between operation convenience and device functionality.
Solution Approach 2:
The tie bundling tool is designed with multi-functionality by incorporating both the binding mechanism (first support with feed groove) and cutting mechanism (cutting groove with rotating cutting bit) into a single device. This universal design enables the tool to perform multiple operations with one hand, improving ease of operation without significantly increasing device complexity.
2Ease of operation
If manpower is used to tighten the stainless steel tie, then the operation is simple, but the binding effectiveness deteriorates due to insufficient friction
Solution Approach 1:
The patent introduces a feed head with a feed groove as an intermediary mechanism between the operator's manual input and the tie tightening process. The feed groove guides and concentrates the manual tightening force, improving the effectiveness of the binding operation while maintaining simplicity. The structured groove geometry mediates the force application to achieve reliable fixation despite the smooth surface of stainless steel ties.
