Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing high tension coil spring structures for bed mattresses suffer from friction noise and limited elasticity due to contact between exposed wiring portions and surrounding wiring portions during compression, leading to reduced comfort and longevity.
Innovation Solution
The high tension coil spring structure incorporates diameter-increasing portions on end wiring portions and rigid support ends to prevent friction noise by allowing exposed wiring portions to move upward and downward without contact, increasing elasticity and longevity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If exposed wiring portions are allowed to move freely during compression, then elasticity is improved, but friction noise occurs due to contact with surrounding wiring portions
Solution Approach 1:
A guide structure is introduced as an intermediary component between the exposed wiring portion and the surrounding environment. This guide structure allows the exposed wiring portion to move vertically during compression while preventing lateral contact with surrounding wiring portions, thereby eliminating friction noise while preserving elasticity.
Solution Approach 2:
The movement path of the exposed wiring portion is segmented into a controlled vertical trajectory using the guide structure. By dividing the potential movement into a defined path, the wiring portion can compress and rebound without unrestricted contact with surrounding components, preventing friction noise generation.
2Object-generated harmful factors
If exposed wiring portions are constrained to prevent friction noise, then noise is reduced, but elasticity is limited
Solution Approach 1:
The guide structure is designed to be dynamically adaptive, allowing the exposed wiring portion to move freely within the vertical direction during compression cycles while maintaining constraints only in lateral directions. This dynamic constraint system preserves the necessary elasticity for shock absorption while preventing friction noise.
Solution Approach 2:
Constraints are applied locally and selectively through the guide structure - lateral movement is constrained to prevent friction noise, while vertical movement is permitted to maintain elasticity. This localized differentiation of constraint quality allows simultaneous achievement of noise reduction and elasticity preservation.
3Device complexity
If exposed wiring portions contact surrounding wiring portions during compression, then friction noise is generated, but structural simplicity is maintained
Solution Approach 1:
The guide structure serves as a simple intermediary component that prevents direct contact between the exposed wiring portion and surrounding wiring portions. This single added element effectively eliminates friction noise generation while maintaining overall structural simplicity and avoiding complex mechanisms.

AI summary
A high tension coil spring structure for a bed mattress includes spring bodies and exposed wiring portions which absorb an external load. Diameter-increasing portions (A) are formed on at least one of upper and/or lower end wiring portions (14, 14') of body wiring portions (12), and provide spaces in which upper and/or lower exposure start wiring portions (16-5, 16-5') move upward and downward. Rigid support ends (18) are formed on at least one of the body wiring portions (12) and upper and lower exposed wiring portions (16, 16'), and absorb a compressive load. The diameter-increasing portions and the rigid ends of the coil spring structure fundamentally prevent noise caused by friction between the exposed wiring portions and surrounding wiring portions when the exposed wiring portions are compressed and significantly increase the elasticity of the exposed wiring portions.
