Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The top size of household springs is typically fixed during design and manufacturing, making it impossible to adjust without compromising the structural balance and performance of the spring module.
Innovation Solution
A tapered spring with a changeable top size, featuring an expandable adjustment member that allows the top size to be adjusted through a rotating mechanism, maintaining stability and balance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the top size of the spring is fixed during design and manufacturing, then the structural balance and performance of the spring module are maintained, but the adaptability to different application needs is reduced
Solution Approach 1:
The spring top structure is transformed from a fixed static configuration to a dynamic adjustable configuration. The adjustment member can be rotated to change the top size, allowing the spring to adapt between different states (smaller top size for compact applications, larger top size for enhanced load-bearing), thus resolving the contradiction between adaptability and structural stability
Solution Approach 2:
The top size parameter of the spring is made variable through the adjustment member mechanism. By rotating the adjustment member, the effective top diameter can be changed between a first size and a second size, enabling the spring to optimize its performance parameters for different application requirements while maintaining structural integrity through controlled parameter transitions
2Strength
If the top size of the spring is increased to enhance load-bearing capacity, then the comfort and support are improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The adjustment member is nested within the spring structure, with the expandable portion containing blades that can be positioned in different configurations. This nested design allows the spring to achieve variable top sizes without requiring completely separate spring structures, thereby reducing overall device complexity while maintaining enhanced load-bearing capacity when needed
Solution Approach 2:
The top portion of the spring is segmented into multiple blades that can be independently positioned and adjusted. This segmentation allows the top size to be modified by reconfiguring the blade positions rather than replacing the entire spring, reducing manufacturing complexity and enabling precise control over load-bearing characteristics
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables flexible adjustment of the top size without disrupting the structural balance, enhancing comfort and load-bearing capacity.
Implementation Method 1
Household springs possess high elasticity, enabling them to support various household devices while offering excellent cushioning and elastic support. Through elastic deformation and rebound, household springs provide support
Implementation Method 2
The adjustment member comprises an expandable portion, and the expandable portion is configured to be expanded and contracted along a horizontal direction on a top end surface of the adjustment member

AI summary
A tapered spring with a changeable top size includes a spring, a tapered fixed sleeve, and an adjustment member. The adjustment member is disposed at a top of the tapered fixed sleeve, and the top of the tapered fixed sleeve is a small end of the tapered fixed sleeve. The adjustment member includes an expandable portion configured to be expanded and contracted along a horizontal direction on a top end surface of the adjustment member, and the expandable portion is configured to be expanded outward to form an outward expansion surface on the top end surface of the adjustment member. When the expandable portion is expanded, a projection of the expandable portion in a vertical direction is less than or equal to a projection of a bottom of the tapered fixed sleeve, and the bottom of the tapered fixed sleeve is the large end of the tapered fixed sleeve.
