Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shock absorbers require disassembly and adjustment of hard points for height adjustment, which is inconvenient and labor-intensive.
Innovation Solution
A shock absorber with an adjustment assembly comprising a stator and rotor, allowing for electromagnetic rotation of the connection end relative to the outer cylinder, enabling height adjustment without disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional shock absorber with fixed hard points is used, then structural stability is maintained, but height adjustment requires disassembly and extensive work
Solution Approach 1:
The shock absorber transitions from a static fixed-structure design to a dynamic adjustable design. The connection end can rotate relative to the outer cylinder through electromagnetic cooperation between stator and rotor, enabling the shock absorber length to be dynamically adjusted without disassembly, thus improving ease of operation while maintaining acceptable device complexity through integrated electromagnetic components.
Solution Approach 2:
The patent replaces traditional mechanical adjustment mechanisms (which would require disassembly of hard points) with an electromagnetic adjustment system. The electromagnetic cooperation between stator and rotor provides rotational motion to the connection end, substituting complex mechanical disassembly operations with a more convenient electromagnetic actuation system.
2Productivity
If electromagnetic adjustment assembly is added, then height adjustment convenience is improved, but device complexity increases
Solution Approach 1:
The electromagnetic adjustment assembly serves multiple functions: the stator and rotor provide both electromagnetic actuation and threaded engagement for rotational motion, the connection end integrates both structural support and adjustable connection functions, and the recessed structure accommodates both the electromagnetic components and the adjustment mechanism within the existing shock absorber footprint. This multi-functionality improves productivity while limiting the increase in device complexity.
