Bicycle Frame Tube Mount for Vibration-Isolated Electronics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bicycle frame designs lack a flexible and robust storage system for electronic components, particularly for electric bicycles, that effectively protects components from vibrations and mechanical forces while accommodating variations in frame tube dimensions and shapes.
Innovation Solution
A bearing system with a housing body and support elements that attach to the inner surface of the frame tube, allowing the housing body to be spaced apart and supported, featuring detachable, expandable, and adjustable elements to fit various frame tubes, and includes interfaces for a floating mount of energy storage devices to absorb mechanical loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the housing body is directly attached to the inner surface of the frame tube, then the mounting is secure and stable, but the component is exposed to vibrations and mechanical forces from the frame tube
Solution Approach 1:
The patent introduces support elements as intermediary components between the housing body and the frame tube's inner surface. These support elements act as a mediator that provides mechanical support while isolating the housing body from direct contact with vibrations and forces transmitted through the frame tube, thus resolving the contradiction between secure mounting and vibration protection.
2Manufacturing precision
If the bearing system is designed to fit a specific frame tube diameter and shape, then the mounting is precise and secure, but the system lacks flexibility for different frame tube variations
Solution Approach 1:
The support elements are designed with dynamic characteristics, allowing them to be axially guided and displaceable during assembly. This enables the support elements to adapt to variations in frame tube diameter and shape while maintaining precise mounting, as they can be positioned optimally during installation rather than requiring a fixed rigid structure.
Solution Approach 2:
The bearing system is designed with universal applicability through detachable support elements that can be configured for different frame tube dimensions. The system can accommodate various frame tube diameters and shapes by adjusting the number and position of support elements, making it versatile across different bicycle frame designs while maintaining secure mounting.
3Reliability
If multiple support elements are used to optimally dissipate forces, then the component protection is improved, but the device complexity increases
Solution Approach 1:
The bearing system divides the support function into multiple detachable support elements that can be independently positioned and configured. This segmentation allows forces to be distributed across multiple contact points with the frame tube, improving component protection while maintaining flexibility in the number and arrangement of support elements based on specific application requirements.
4Ease of operation
If the support elements are detachably attached to the housing body, then the system allows easy installation and removal, but the mounting security may be reduced
Solution Approach 1:
The detachable support elements are designed to be axially guided and displaceable during assembly, allowing them to be easily installed and removed. Once positioned, they provide secure mounting through optimal force distribution and contact with the frame tube, achieving both ease of operation and mounting security through their dynamic positioning capability.
