Bicycle Seatpost Cable Connecting Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bicycle seatpost assemblies require tools for attaching and adjusting control cables, which can be inconvenient for users.
Innovation Solution
A bicycle seatpost assembly with a cable connecting device that includes two cables with nipple and nipple hooked portions, allowing for tool-free attachment and adjustment, and a cable connecting device with tension adjusters and stoppers for secure and easy cable management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single control cable with a single nipple portion is used, then the structure is simple, but tools are required for attaching and adjusting the cable
Solution Approach 1:
The single control cable is segmented into two separate cables (first cable and second cable), each with their own nipple portions. This segmentation allows each cable to be independently attached using simple hooking actions rather than requiring clamp mechanisms and tools, thus resolving the contradiction between structural simplicity and ease of operation.
Solution Approach 2:
The cable connecting device acts as an intermediary component that receives both the first and second cables. It provides a centralized location with multiple cable receiving portions that facilitate tool-free attachment while maintaining structural organization, thereby improving ease of operation without significantly increasing overall device complexity.
2Reliability
If a clamp mechanism is used to attach the cable without a nipple portion, then the cable can be secured, but tools are required for attachment and adjustment
Solution Approach 1:
The cable connecting device is designed to be self-servicing through its cable receiving portions that accept nipple portions via simple hooking actions. The built-in cable tension adjuster allows users to independently adjust cable tension without requiring external tools or mechanisms, thereby achieving both reliable attachment and ease of operation.
3Device complexity
If cables are connected without tension adjustment capability, then the structure is simpler, but proper cable tension cannot be optimized
Solution Approach 1:
The cable tension adjuster is merged into the cable connecting device, combining the functions of cable connection and tension adjustment in a single integrated component. This merging allows the device to provide proper cable tension optimization without requiring separate adjustment mechanisms, thus maintaining structural simplicity while improving ease of operation.

AI summary
A first cylinder, a second cylinder configured to be telescopically received therein are provided, a positioner configured to relatively position the first cylinder and the second cylinder, an operator configured to be mounted to a bicycle and operatively coupled to the positioner, and a control cable. The control cable may include an outer casing, a first cable having a first end and a second end and configured to be operatively connected to the positioner at the first end, and a second cable having a third end and a fourth end. The second cable may be configured to be operatively connected to the operator at the third end. A cable connector may be configured to connect the second end of the first cable and the fourth end of the second cable.
