Multi-piece Nut for Shock Absorber Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing coil spring over shock systems require significant labor to disassemble and adjust, as the spring nut must be completely removed from the shock absorber to change the spring or make repairs, leading to inefficiencies in maintenance and adjustment.
Innovation Solution
A multi-piece nut design comprising a first and second nut member that are removably coupled, forming an aperture to engage the shock absorber, allowing for adjustment and maintenance without full disassembly, with optional dampening devices to reduce vibration and noise.

Engineering Contradiction Analysis
1Ease of operation
If a single-piece spring nut is used to secure the coil spring to the shock absorber, then the connection is strong and reliable, but significant labor is required to disassemble and adjust the spring
Solution Approach 1:
The spring nut is divided into multiple separable components: a body portion that threads onto the shock absorber and retains the spring, and a separate lock portion that secures the body to the shock. This segmentation allows the lock portion to be removed independently for adjustment while the body remains attached, eliminating the need to fully disassemble the nut for spring changes.
Solution Approach 2:
The nut transitions from a static, fixed structure to a dynamic, adjustable system. The separable lock portion can be independently removed and reattached, enabling the nut to change its state between locked and unlocked positions. This dynamic capability allows quick adjustment without complete disassembly while maintaining structural integrity when locked.
2Ease of repair
If the spring nut is completely removed from the shock absorber to change the spring, then the spring can be replaced, but considerable labor and time are required for disassembly and reassembly
Solution Approach 1:
The nut's lock portion is separated from the body portion, allowing the lock to be independently removed. This enables mechanics to access and replace the spring by simply removing the lock portion rather than completely disassembling the entire nut assembly, significantly reducing maintenance time and effort.
Solution Approach 2:
The lock portion is extracted as a separate functional element from the nut body. This extracted lock can be independently manipulated and removed to provide access to the spring, allowing spring replacement without removing the entire nut assembly from the shock absorber.
3Productivity
If a multi-piece nut design is used to allow adjustment without full disassembly, then labor and time are reduced, but the nut structure becomes more complex
Solution Approach 1:
The nut is segmented into functional modules (body and lock portions) that can be independently manufactured and assembled. This modular segmentation improves maintenance efficiency by allowing quick access to the spring while keeping the overall structure relatively simple through standardized connection interfaces between segments.

AI summary
A multi-piece nut for use with a shock is provided. The multi-piece nut includes a first nut member and a second nut member removably coupled to the first nut member. The first nut member and second nut member include threads on an inner surface that correspond to each other when coupled together. The multi-piece nut may also include an aperture formed when the first nut member and second nut member are coupled together. The first and second nut members are coupled around a shock absorber, and the shock absorber extends through the aperture and engages the threads. The nut can then be rotated to adjust the spring of the shock.
