Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Adjusting the seat position on a bicycle, especially when riding over varied terrain, is challenging due to the need to balance weight on the seat while making adjustments, which can be difficult and inconvenient.
Innovation Solution
A bicycle telescopic apparatus comprising a first tube, a second tube, a positioning structure, a memory, and a controller, allowing for electrical adjustment of the seat height with a position sensor to detect and automatically set predetermined positions, enabling easy height changes via a remote device without the need for manual balancing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user places their weight on the seat to adjust the seat position while riding, then the seat height can be changed, but it becomes challenging to adjust when riding over varied terrain
Solution Approach 1:
The patent replaces the mechanical weight-based adjustment system with an electrical actuator system. The electrical actuator receives control signals from a remote control device to automatically adjust the seat post extension, eliminating the need for the rider to manually balance their weight on the seat during adjustment. This substitution of mechanical operation with electrical control resolves the contradiction by providing reliable, stable adjustment capability regardless of terrain conditions.
2Device complexity
If manual weight-based adjustment is used, then no additional components are needed, but the adjustment process becomes difficult and inconvenient
Solution Approach 1:
The patent introduces an electrical actuator controlled by a remote control device to replace manual weight-based adjustment. Although this increases device complexity by adding electrical components, it dramatically improves ease of operation by allowing the rider to adjust seat height conveniently using the remote control without needing to balance their weight on the seat.
Solution Approach 2:
The patent introduces a remote control device as an intermediary between the rider and the seat adjustment mechanism. This intermediary allows the rider to issue adjustment commands from a convenient location (such as the handlebars) rather than needing to directly manipulate the seat post mechanism, thereby improving operational ease despite adding system complexity.
3Ease of operation
If an electrical actuator is added to enable easy adjustment, then ease of operation improves, but device complexity increases
Solution Approach 1:
The patent accepts the increased device complexity as a necessary trade-off to achieve the desired ease of operation. By substituting the simple mechanical weight-based system with an electrical actuator and remote control system, the rider gains convenient, precise control over seat height adjustment without needing to manually balance their weight, particularly beneficial when riding over varied terrain.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables users to easily and conveniently adjust the seat height according to terrain and personal preference, improving comfort and control while riding by allowing for wireless, electronic control of the seatpost's length within a variable range.
Implementation Method 1
The positioning structure includes an electrical actuator to adjustably position the second tube relative to the first tube in the longitudinal direction
Implementation Method 2
a position sensor configured to detect the predetermined relative position of the first tube and the second tube, and the position sensor outputs a signal to position the second tube relative to the first tube at the predetermined relative position
Implementation Method 3
the position sensor includes a pressure sensor configured to detect a pressure of an air chamber biasing the second tube relative to the first tube in an extending direction

AI summary
A bicycle telescopic apparatus includes a first tube, a second tube, a positioning structure, a memory, and a controller. The second tube is telescopically received in the first tube and configured to be adjustably movable with respect to the first tube in a longitudinal direction of the bicycle telescopic apparatus. The positioning structure includes an electrical actuator to adjustably position the second tube relative to the first tube in the longitudinal direction. The memory is configured to store setting information for a predetermined relative position of the first tube and the second tube, and the setting information is changed via an electrical setting operation. The controller is configured to control the electrical actuator to position the second tube relative to the first tube at the predetermined relative position.
