Coil Disk Clamping Ribs for Glue-Free Coil Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coil disks used in cooking utensils produce a peculiar smell when heated due to the use of glue for fixation, which is undesirable for user experience.
Innovation Solution
A coil disk design featuring a support structure with first and second clamping ribs that form a clamping gap for winding enameled wire, eliminating the need for glue and enhancing stability and efficiency of coil fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If glue is used to fix the coils, then the coil fixation is simple and efficient, but the glue produces peculiar smell when heated
Solution Approach 1:
The patent removes the harmful glue material from the coil fixation system and replaces it with a mechanical clamping structure consisting of clamping ribs and clamping gaps. This extraction eliminates the source of the peculiar smell while maintaining the coil fixation function through physical constraint rather than chemical adhesion.
Solution Approach 2:
The patent substitutes the chemical bonding mechanism of glue with a mechanical clamping system. The clamping ribs create physical gaps that constrain the coil windings through mechanical force, replacing the adhesive bonding process. This substitution maintains fixation effectiveness while eliminating thermal decomposition odors from the glue.
2Ease of manufacture
If glue is used to fix the coils, then the manufacturing process is simple, but the coil stability at high temperature deteriorates
Solution Approach 1:
The patent extracts the temperature-sensitive glue material and replaces it with a thermally stable mechanical clamping structure. The clamping ribs and gaps provide consistent mechanical constraint at high temperatures where glue would decompose, ensuring reliable coil fixation throughout the operating temperature range.
Solution Approach 2:
The patent changes the fixation mechanism from chemical (glue) to mechanical (clamping structure). This parameter change transforms the temperature-dependent adhesive properties into temperature-independent mechanical constraints, maintaining coil stability across varying thermal conditions without sacrificing manufacturing simplicity.
