Bike Sensor Device Internal Frame Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bike sensor systems that record speed and distance data often require cables routed outside the bike frame, which is not optimal for various bike designs and can be cumbersome for user-assembled bikes, especially e-bikes where speed limits impact classification and registration.
Innovation Solution
A bike sensor device with a sensor housing and cable that can be securely mounted within the bike frame using a form-fitting and force-fitting sensor holder, adaptable to both tubular and solid frame structures, ensuring a sealed and stable installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If cables are routed externally along the bike frame, then the sensor system can be implemented, but the design becomes cumbersome and does not fit optimal bike design
Solution Approach 1:
The sensor housing is inserted into a receptacle within the bike frame tube, nesting the sensor system inside the frame structure. This eliminates external cable routing and integrates the sensor device into the bike frame's internal space, resolving the contradiction between ease of assembly and device complexity.
2Reliability
If a sensor holder is designed for secure mounting, then the sensor housing is firmly fixed, but the installation process becomes more complex
Solution Approach 1:
The sensor holder is divided into separate components: a receptacle integrated into the frame and a removable sensor holder assembly. This segmentation allows the sensor housing to be independently inserted and secured, providing reliable mounting while simplifying the installation process through modular assembly.
Solution Approach 2:
The receptacle is pre-formed within the frame tube during frame manufacturing, and the sensor holder is pre-assembled with mounting features. This preliminary preparation eliminates the need for complex on-site installation procedures while ensuring secure mounting, resolving the contradiction between reliability and installation complexity.
3Adaptability or versatility
If the sensor holder is adapted to different frame structures, then versatility is improved, but the design complexity increases
Solution Approach 1:
The sensor holder is designed with universal features that allow it to be adapted to different frame structures (tubular or solid material). The receptacle can be integrated into various frame types, and the sensor holder assembly maintains consistent mounting mechanisms, providing versatility without significantly increasing design complexity.

AI summary
The invention relates to a bike sensor device having a sensor housing and a sensor cable connected thereto. The sensor device further comprises a sensor mount for holding the sensor housing in place on or in the bike frame. The sensor mount is adapted to a receptacle or opening on/in the bike frame, and the sensor mount together with the sensor housing is received interlockingly and/or frictionally on/in the bike frame (3, 23).
