Retractable Locking Shackle Embedded in Bicycle Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bicycle locks and electronic security devices are susceptible to tampering, easily accessible, and affect the aesthetics of the bicycle, while also being prone to dust and water ingress, leading to inefficiencies and unnecessary expenses.
Innovation Solution
An electronic security device is embedded within the bicycle frame, featuring a retractable locking shackle that can assume a locked or retracted position based on user signals, with an electronic control module for wireless control and a rechargeable battery for power, and is designed to be securely integrated within hollow spaces of the frame to prevent unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional locks are used to secure bicycles, then security is provided, but the locks are susceptible to tampering and easily accessible by unauthorized persons
Solution Approach 1:
The locking mechanism is extracted from the traditional external lock position and integrated into the bicycle frame's hollow space. The locking shackle is housed within the frame structure, removing it from external accessibility while maintaining its security function. This extraction principle directly addresses the tampering susceptibility issue by hiding the critical locking components inside the frame.
Solution Approach 2:
The locking shackle and electronic security device are nested within the hollow space of the bicycle frame. The shackle assumes a locked position extending through openings in the frame and a retracted position within the hollow space. This nesting approach protects the locking mechanism from external tampering while preserving its functionality.
2Reliability
If conventional locks are placed on bicycles, then security is provided, but the placement spoils the aesthetics of the bicycle
Solution Approach 1:
The locking mechanism is extracted from visible external positions and relocated to the hollow space within the frame. This extraction eliminates the visual impact of traditional locks on the bicycle's aesthetics while maintaining security functionality through strategic opening placements.
Solution Approach 2:
The security device is nested within the frame's hollow space, utilizing the existing structural volume. This nesting allows the locking mechanism to be concealed within the frame geometry, preserving the bicycle's aesthetic appearance while providing secure locking capability.
3Reliability
If conventional electronic security devices are used, then security is improved, but they remain conspicuous and susceptible to tamper
Solution Approach 1:
The electronic security device is extracted from external mounting positions and integrated into the hollow space of the frame. This extraction conceals the electronic components, control unit, and power supply within the frame structure, eliminating conspicuousness while maintaining security functionality.
Solution Approach 2:
The electronic security device, including control unit and power supply, is nested within the hollow space of the frame. This nesting approach hides the electronic components from view and protects them from tampering, addressing both conspicuousness and security concerns simultaneously.
4Ease of operation
If conventional locks and electronic security devices are placed externally, then accessibility for operation is maintained, but they are prone to dust and water seepage
Solution Approach 1:
The frame structure acts as an intermediary protective barrier between the electronic security device and the external environment. The hollow space and frame material shield the electronic components from dust and water seepage, while controlled openings allow necessary operational access.
Solution Approach 2:
The electronic security device is nested within the protected hollow space of the frame, which serves as a environmental barrier. This nesting protects sensitive electronic components from dust and water while maintaining operational accessibility through strategically positioned openings.

AI summary
A bicycle (100) includes a frame (105) and an electronic security device (110). The frame (105) includes a hollow space (400) and at least one opening (310A,310B). The hollow space (400) is configured within the frame (105). The at least one opening (310A,310B) is configured in the frame (105) and the at least one opening (310A,310B) is connected to the hollow space (400). The electronic security device (110) is configured such that it is accommodated within the hollow space (400) of the frame (105). The electronic security device (110) includes a retractable locking shackle (140) configured to assume a locked position and a retracted position by moving through the at least one opening (310A,310B) configured in the frame (105). The locked position of the retractable locking shackle (140) restricts a movement of a wheel (117) of the bicycle (100) and the retracted position enables free movement of the wheel (117) of the bicycle (100).
