Electric Seatpost Assembly with Integrated Switch Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric seatpost assemblies for bicycles often require remote switches near the handlebar, leading to complex wiring and increased component count, which complicates the adjustment of seatpost length.
Innovation Solution
An electric seatpost assembly with a switch unit integrated into the seatpost, allowing for length adjustment without a remote switch, featuring a controller and positioning structure that uses a push button or lever for manual operation, enabling easy manipulation and simplifying wiring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a remote switch near the handlebar is used for seatpost length adjustment, then the rider can easily manipulate the switch, but the wiring becomes complex and the number of components increases
Solution Approach 1:
The patent integrates the switch unit directly into the seatpost assembly, merging the control function with the mechanical structure. This eliminates the need for separate remote switches near the handlebar and simplifies the wiring system by reducing the distance and complexity of electrical connections between the switch and controller
2Ease of operation
If a remote switch near the handlebar is used for seatpost length adjustment, then the rider can easily manipulate the switch, but the number of parts increases
Solution Approach 1:
The switch unit is combined with the seatpost assembly into a single integrated component. This reduces the total number of parts by eliminating the need for separate remote switches and their associated mounting hardware, while maintaining ease of operation through the integrated design
3Device complexity
If the switch unit is integrated into the seatpost, then the wiring is simplified and components are reduced, but the switch must be accessible to the rider
Solution Approach 1:
The switch unit is positioned on the seatpost at a location that provides both wiring simplicity and rider accessibility. The design considers the local characteristics of the seatpost structure to place the switch in an optimal position that balances the trade-off between simplified integration and ease of manipulation by the rider

AI summary
An electric seatpost assembly comprises a first member, a second member, a positioning structure, a controller, and a switch unit. The second member is movably coupled to the first member so as to change a length of the electric seat post assembly. The positioning structure is configured to position the second member relative to the first member. The controller is to control the positioning structure. The switch unit is provided on one of the first member and the second member to transmit at least one electric signal to the controller.
