Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coil spring devices require surface treatment of the inner surface of the support groove with chemicals like chlorine-containing substances, increasing manufacturing time and facility restrictions.
Innovation Solution
A coil spring device where the lower end of the main body spring is adhered to a support plate made of plastic or metal, eliminating the need for surface treatment on the inner surface of the support groove.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If surface treatment is performed on the inner surface of the support groove using chlorine-containing chemicals and organic solvents, then adhesion reliability is improved, but manufacturing time increases and facility restrictions occur
Solution Approach 1:
A support plate made of plastic or metal material is introduced as an intermediary component between the main body spring and the rubber insulator. The support plate is fixed to the inner surface of the support groove, and the lower end part of the main body spring is adhered to the support plate instead of directly to the rubber insulator. This intermediary structure enables reliable adhesion without requiring surface treatment of the rubber insulator, thereby eliminating the need for chlorine-containing chemicals and organic solvents while reducing manufacturing time and facility restrictions.
2Reliability
If surface treatment is performed on the inner surface of the support groove, then adhesion reliability is improved, but manufacturing complexity increases
Solution Approach 1:
The support plate serves as a mediator that simplifies the manufacturing process. By fixing the support plate to the support groove and adhering the main body spring to the support plate, the complex surface treatment process is eliminated. The support plate can be easily fixed using conventional methods such as insertion, pressing, or vulcanization, significantly reducing manufacturing process complexity while maintaining adhesion reliability.
3Reliability
If surface treatment is performed on the inner surface of the support groove, then adhesion reliability is improved, but facility restrictions occur
Solution Approach 1:
The support plate intermediary structure eliminates the need for specialized surface treatment facilities. The support plate can be fixed to the support groove using simple conventional methods such as insertion, pressing, or vulcanization, which can be performed using standard manufacturing equipment. This removes the restriction of needing specialized facilities for surface treatment with chlorine-containing chemicals and organic solvents, thereby improving ease of manufacture.
