Reversible Preload Spacer for Adjustable Coilover Suspension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current coilover shock absorbers lack adjustability for spring compression and ride height, limiting the ability to customize vehicle suspension settings without requiring complex modifications or additional components.
Innovation Solution
The introduction of reversible preload spacers that can be installed in different orientations to provide multiple settings of spring compression, allowing for adjustable ride height adjustments by engaging with the shock tube and spring perch, and optionally combined with shims for additional height settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If coilover shock absorbers are designed as single-unit assemblies, then vehicle weight is reduced, but adjustability for spring compression and ride height is limited
Solution Approach 1:
The preload spacer is divided into two portions that can be attached together, creating a modular component that provides multiple adjustment settings. This segmentation allows the single-unit coilover assembly to gain adjustability through a modular additive component rather than requiring complex modifications to the shock absorber itself.
Solution Approach 2:
The preload spacer acts as an intermediary component installed between the spring perch and the shock tube. This mediator provides the desired adjustability for spring compression and ride height without modifying the original coilover shock absorber assembly, maintaining system simplicity while adding functionality.
2Adaptability or versatility
If reversible preload spacers with multiple orientations are used, then ride height adjustability is enhanced, but device complexity increases
Solution Approach 1:
The preload spacer incorporates an asymmetrical engagement structure that engages with a groove on the shock tube at different positions depending on orientation. This asymmetry enables two distinct ride height settings through simple rotation of the spacer, providing enhanced adjustability without complex mechanisms.
Solution Approach 2:
The preload spacer is designed to be reversible and rotatable, transforming from a static component to a dynamic one that can assume multiple orientations. This dynamic capability allows users to adjust ride height by rotating the spacer to different positions, enhancing versatility without requiring complex adjustment mechanisms.

AI summary
A reversible, two setting preload spacer includes a body extending along an axis between a first end and a second end. The spacer also includes an opening formed through the body and extending along the axis from the first end to the second end. The opening is defined by an inner surface and configured to receive a portion of a shock tube of a shock absorber. The spacer also includes an engagement structure configured to engage a groove on the shock tube positioned on the inner surface. The engagement structure is positioned such that a first distance between the engagement structure and the first end is greater than a second distance between the engagement structure and the second end.
