Spring structure with adjustable hardness and spring package
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing household spring structures lack the ability to adjust softness-hardness levels after assembly, limiting user customization and comfort adjustment.
Innovation Solution
A spring structure with an adjustable hardness mechanism, comprising a spring, an adjustment member, and a wrapping member, allows for manual adjustment of pre-compression force through a rotating member and moving member to change the tension space of the spring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the spring structure is assembled with fixed pre-compression force, then the manufacturing process is simple and fast, but the softness-hardness level cannot be adjusted after assembly
Solution Approach 1:
The patent applies the dynamics principle by introducing an adjustable mechanism that transforms the fixed spring structure into a dynamic one. The adjustment member with rotating member, moving member, and support member enables the pre-compression force to be modified after assembly, allowing the spring structure to adapt to different softness-hardness requirements while maintaining a relatively simple assembly process.
2Adaptability or versatility
If the spring structure includes adjustable mechanism, then the softness-hardness level can be adjusted after assembly, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the adjustment function into distinct components: rotating member for input, moving member for transmission, and support member for guidance. This modular segmentation allows the adjustable mechanism to be integrated into the existing spring structure without requiring a complete redesign, thus managing complexity while achieving adaptability.
Solution Approach 2:
The dynamics principle is applied through the adjustable mechanism that enables post-assembly modification of pre-compression force. The rotating member, moving member, and support member work together to create a dynamic adjustment system that adds functionality without excessive complexity.
3Strength
If the pre-compression force is increased, then the support hardness is improved, but the comfort and resilience are reduced
Solution Approach 1:
The patent applies dynamics by enabling the pre-compression force to be adjusted after assembly based on user preference and specific application requirements. This allows optimization of the balance between support hardness and comfort/resilience, rather than being locked into a fixed design compromise.
Solution Approach 2:
The patent applies parameter changes by allowing the pre-compression force parameter to be modified through the adjustment mechanism. Users can change this parameter to achieve different levels of support hardness while maintaining comfort and resilience, effectively decoupling the trade-off present in fixed designs.
