Bicycle Clamping Device with Automatic Cycling State Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clamping devices for bicycles lack security and operational convenience, particularly for novice riders who may experience '0-velocity crashes' due to delayed unlocking in emergency situations, as they require manual rotation of both feet to unlock.
Innovation Solution
A clamping device with a control module that acquires cycling information such as pedaling frequency and acceleration to automatically lock or unlock the device based on the cycling state, using sensors and a driving motor to rotate the clamping device body relative to the locking sheet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual rotation of feet is used to unlock the clamping device, then the device structure remains simple, but the security and operation convenience deteriorate due to delayed unlocking in emergency situations
Solution Approach 1:
The clamping device automatically detects cycling state through sensors (acceleration sensor, pedaling frequency sensor) and self-adjusts the locking state without requiring manual intervention from the cyclist. The control module processes sensor data and automatically controls the driving motor to lock or unlock the device based on detected cycling conditions, making the system serve itself rather than requiring continuous human operation.
Solution Approach 2:
The patent replaces the purely mechanical manual unlocking system with an integrated electromechanical system. Sensors detect cycling state and convert mechanical motion into electrical signals, the control module processes these signals electronically, and the driving motor converts electrical commands back into mechanical rotation to adjust the locking state, substituting manual mechanical operation with an automated electromechanical control system.
2Ease of operation
If automatic locking and unlocking control is implemented based on cycling state, then operation convenience improves, but device complexity increases due to additional sensors and control modules
Solution Approach 1:
The system continuously monitors cycling state through integrated sensors and automatically adjusts locking status without requiring the cyclist to manually operate the device. The control module processes sensor data in real-time and automatically commands the driving motor to lock or unlock based on detected conditions, making the system self-regulating and eliminating the need for manual intervention.
Solution Approach 2:
The control module serves multiple functions: it receives and processes signals from multiple different sensors (acceleration sensor, pedaling frequency sensor), determines cycling state based on various parameters, and controls the driving motor to adjust locking status. This multi-functional integration allows a single control module to handle sensing, processing, decision-making, and actuation, reducing the need for separate dedicated components for each function.
3Productivity
If the clamping device remains locked during braking, then pedaling frequency maintenance is improved, but harmful factors increase due to '0-velocity crash' risk when braking stops the bicycle
Solution Approach 1:
The system uses acceleration sensors to continuously monitor the bicycle's motion state and provides feedback to the control module. When the acceleration sensor detects that the bicycle has stopped (zero velocity condition during or after braking), this feedback triggers the control module to automatically unlock the clamping device, preventing the cyclist from falling off. The feedback loop continuously monitors and adjusts the locking state based on real-time cycling conditions.
Solution Approach 2:
The control module proactively unlocks the clamping device when it detects braking conditions or zero velocity states, performing the unlocking action before the cyclist would naturally need to do so manually. By detecting the braking state in advance through acceleration sensors and automatically initiating the unlocking sequence, the system prevents the harmful situation of being locked during or after stopping, rather than waiting for the problem to occur.
