Extended Electrician Pliers Sleeves for Hidden Wire Knife Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrician pliers have aesthetic issues due to welding lines and polished marks, and they do not fully utilize spatial positions, limiting their functional range and increasing manufacturing costs.
Innovation Solution
The electrician pliers feature extended plier sleeves that cover the wire winding and splitting parts, shielding welding lines and improving aesthetics, while also utilizing additional spatial positions to enhance functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wire winding knife and wire splitting knife are welded in via holes, then the knives are stably mounted on the jaw, but welding lines and polished marks are generated causing aesthetic issues and increased processing time
Solution Approach 1:
The patent extracts the harmful welding lines and polished marks from the visible surface by positioning the knives inside recessed via holes. The knives remain mounted through the holes, but the welding and polishing operations occur hidden within the hole structure, eliminating aesthetic defects from the external surface while maintaining stable mounting.
Solution Approach 2:
The via holes act as an intermediary structure between the mounting process and the external surface. By performing welding and polishing operations within the confined space of the via holes rather than on the surface, the process isolates the harmful effects (welding lines and marks) from the visible aesthetic areas, resolving the contradiction between reliable mounting and manufacturing simplicity.
2Device complexity
If traditional plier structure is used, then the structure is simple, but the spatial position of plier bodies is not fully utilized limiting functional range
Solution Approach 1:
The patent applies multi-functionality by integrating multiple functional components (wire winding knife, wire splitting knife, and additional tools) into the plier structure. The via holes in the jaw are utilized to mount various knives and tools, allowing a single plier device to perform multiple wire handling functions, thereby expanding adaptability while maintaining relatively simple overall structure.
Solution Approach 2:
The patent utilizes the third dimension by drilling via holes into the jaw structure, creating vertical mounting positions for knives. This vertical dimension within the jaw allows multiple functional elements to be integrated without increasing the horizontal footprint or overall structural complexity, effectively using spatial volume to enhance functionality.
