Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional suspension systems in linear oscillation systems are bulky and prone to misalignment, leading to increased friction and reduced efficiency due to direct contact between moving and stationary members, which results in higher energy consumption and frictional losses.
Innovation Solution
A suspension system comprising a combination of planar and longitudinal elastic members with variable diameters, providing an axially flexible and radially rigid connection, and a method of assembly that ensures proper alignment of the moving and stationary assemblies to minimize direct contact and misalignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional longitudinal springs are used in the suspension system, then the moving member can be restrained during reciprocating motion, but the moving member experiences displacement and misalignment leading to direct contact with the stationary member
Solution Approach 1:
The suspension system is divided into multiple independent elastic members (first longitudinal elastic member, second longitudinal elastic member, first planar elastic member, second planar elastic member) distributed around the moving member. Each member independently provides restraint force, collectively preventing direct contact while maintaining alignment through distributed support rather than concentrated spring force.
Solution Approach 2:
The patent employs planar elastic members (thin flexible elements) in combination with longitudinal elastic members. These flexible planar members provide restraint forces while accommodating minor misalignments through their flexibility, preventing direct contact between the moving member and stationary member without causing rigid displacement.
2Manufacturing precision
If dimensional tolerance is used to align the moving member and stationary member, then alignment can be achieved, but direct contact occurs during operation due to suspension system displacement
Solution Approach 1:
Instead of relying on a single suspension element that may cause displacement, the system uses multiple segmented elastic members distributed around the moving member. This segmentation distributes the restraint forces evenly, maintaining the aligned position established by manufacturing tolerances throughout the reciprocating motion cycle.
Solution Approach 2:
The patent changes the parameters of the suspension system by using multiple elastic members with specific geometric configurations (longitudinal and planar arrangements) rather than conventional single spring systems. This parameter change enables the system to maintain the alignment position while providing necessary restraint forces.
3Loss of energy
If direct contact between moving member and stationary member is avoided, then frictional losses are reduced, but the suspension system becomes more complex
Solution Approach 1:
The patent merges multiple elastic members (longitudinal and planar types) into a unified suspension system that collectively provides restraint forces. This combined approach prevents direct contact between the moving member and stationary member, reducing frictional losses while distributing the complexity across multiple simple, standardized elastic components rather than a single complex mechanism.
