Bicycle Fork Sag Marking Assembly for Accurate Suspension Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current suspension tuning methods for vehicles, particularly bicycles, are complex and subjective, making it difficult for riders to set the initial sag correctly, which affects ride handling and performance.
Innovation Solution
The implementation of a shock sag value generating assembly on the front fork assembly of bicycles, which includes visible marks on the arch and upper tubes to indicate sag percentages, allowing riders to easily set and verify the sag setting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional suspension tuning methods using calculations and equations are used, then measurement precision may be improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent creates visual copies of sag measurement information by placing reference marks directly on the fork arch and upper tube. Instead of requiring riders to perform calculations, the system provides visual representations (marks at specific positions) that directly indicate sag percentages, making the information immediately accessible and easy to interpret.
Solution Approach 2:
The patent replaces the mechanical/cognitive system of calculations and equations with a visual marking system. Riders no longer need to perform mathematical operations or understand complex tuning equations; instead, they simply observe the position of reference marks relative to the fork structure to determine sag settings.
2Measurement precision
If traditional suspension tuning methods using calculations and equations are used, then measurement precision may be improved, but device complexity deteriorates
Solution Approach 1:
The patent creates visual copies of sag measurement information by placing reference marks directly on the fork arch and upper tube. Instead of requiring riders to perform calculations, the system provides visual representations (marks at specific positions) that directly indicate sag percentages, making the information immediately accessible and easy to interpret.
Solution Approach 2:
The patent extracts the essential measurement information (sag percentage) and presents it in a simplified visual form through reference marks. The complex calculation processes are removed from the user interface, leaving only the visual indication of sag settings that riders need to observe and adjust.
3Ease of operation
If visual marks are added to the fork assembly, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The reference marks are pre-positioned on the fork arch and upper tube during manufacturing or assembly. This preliminary action ensures that the marks are correctly positioned to indicate accurate sag percentages, eliminating the need for riders to perform measurements or calculations during the tuning process.
Solution Approach 2:
The patent creates visual copies of sag measurement information by placing reference marks directly on the fork arch and upper tube. Instead of requiring riders to perform calculations, the system provides visual representations (marks at specific positions) that directly indicate sag percentages, making the information immediately accessible and easy to interpret.

AI summary
A shock sag value generating assembly is disclosed. The shock includes an upper tube telescopically engaged with a lower tube, and the sag value generating assembly includes a first sag value generating component located relative to one of the upper tube and the lower tube and a second sag value generating component slidably coupled about an outer diameter of one of the upper tube and the lower tube.
