Bicycle Frame Shock Absorber Dial Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bicycle frames with rear shock absorbers face challenges in integrating the shock absorber into the frame while maintaining user accessibility to adjustment controls, often resulting in less accessible and less integrated solutions.
Innovation Solution
A bicycle frame design featuring a depression in one of the tubes with a window that allows the compression dial to be hidden inside the frame, connected via an actuator element, enabling remote compression activation and maintaining accessibility to all dials for user adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the shock absorber is integrated into the frame by locating it on the lower part of the bicycle frame, then the integration and aesthetics are improved, but the accessibility to compression and rebound dials deteriorates
Solution Approach 1:
The frame tube is segmented into an outer part and an inner part, with the shock absorber positioned in the inner part. This segmentation allows the shock absorber to be integrated into the frame structure while maintaining accessibility to its controls through the window opening in the outer part.
Solution Approach 2:
The shock absorber is nested within the inner part of the frame tube, with the compression dial and actuator element arranged concentrically. The actuator element extends through the window opening to reach the compression dial, enabling remote operation while maintaining integrated appearance.
2Shape
If the compression dial is hidden inside the frame to improve integration, then the aesthetics are improved, but the ease of adjusting compression deteriorates
Solution Approach 1:
The actuator element serves as an intermediary mechanism that extends from the outer part of the frame through the window opening to connect with the compression dial inside the inner part. This allows the compression dial to be hidden while remaining adjustable through the actuator element's motion.
Solution Approach 2:
The actuator element extends in a different spatial dimension (radially outward through the window) to reach the compression dial located in the inner part. This dimensional extension allows remote operation of the hidden dial without compromising integration.

AI summary
The invention relates to a bicycle frame (1) with a remote-controlled shock absorber (2) connected to the frame (1). The shock absorber (2) comprises two dials (3, 4) for adjusting the compression and rebound. The frame (1) is characterised in that it comprises a depression (9; 25) communicated with the outside of the frame (1) and provided with a window (12; 28) that communicates the depression (9; 25) with an inner part (8b; 18b) of the frame (1). An actuator element (7) for adjusting the compression dial (3) extends from the outside of the frame (1) towards the window (12; 28) passing through the inner part (8b; 18b) of the frame (1). The invention improves the integration of the rear suspension of the bicycle while simultaneously allows for easy adjustment of the compression dial (3) and the rebound dial (4).
