Innovation Solution
A bicycle inductive lock design featuring a control circuit device with an induction unit, power unit, and key fob that uses a speed reduction motor to toggle baffles for locking and unlocking, cooperating with a steel cable, and includes features like induction switches and a power-saving mechanism to prevent erroneous locking and conserve energy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If GPS positioning module and GSM module are installed to provide positioning and communication functions, then the functionality and convenience are improved, but the power consumption increases significantly
Solution Approach 1:
The patent removes the GPS positioning module and GSM module from the system, extracting only the essential locking and unlocking functions. This eliminates the high power consumption associated with continuous satellite positioning and cellular communication while retaining the core security functionality through a simplified inductive lock mechanism.
Solution Approach 2:
The patent replaces expensive, high-power consumption modules (GPS and GSM) with a simple, low-cost inductive switching mechanism. The inductive switch provides sufficient functionality for locking/unlocking without the need for continuous power-intensive operations, effectively using a simpler, shorter-lived technical solution to replace complex systems.
2Ease of operation
If inductive locking mechanism is used for convenience, then the ease of operation is improved, but the risk of accidental locking increases
Solution Approach 1:
The patent incorporates a time-delay mechanism that requires the user to hold the RFID card against the感应 area for a predetermined period before the locking mechanism activates. This preliminary action prevents accidental locking by ensuring intentional user input, while still maintaining the convenience of contactless operation.
Solution Approach 2:
The system provides visual or auditory feedback to confirm whether the locking operation has been successfully initiated. This feedback mechanism allows users to verify that their action was registered correctly, preventing unintended locking and providing reassurance during operation.
3Ease of operation
If battery power is used to drive the locking mechanism, then the ease of operation is improved, but the reliability decreases when battery is exhausted
Solution Approach 1:
The patent designs the locking mechanism to be mechanically self-contained, using a spring-loaded return system that automatically resets the locking components after each operation. This mechanical self-service ensures the lock remains functional even when electrical power is depleted, as the basic locking and unlocking actions rely on mechanical energy storage and release rather than continuous battery power.
Solution Approach 2:
The system incorporates a mechanical spring mechanism that stores energy in advance to facilitate the locking and unlocking actions. This beforehand cushioning ensures that even when the battery is exhausted, the mechanical components have sufficient stored energy to complete the locking cycle, maintaining reliability under power-depleted conditions.
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
The solution enhances convenience and practicality by reducing accidental locking, minimizing power consumption, and ensuring reliable locking and unlocking functionality even when batteries are low, while providing a secure anti-theft mechanism using a steel cable.
Implementation Method 1
The key fob enables the induction unit to sense a signal, thereby driving the speed reduction motor to move the first baffle and the second baffle

AI summary
A bicycle inductive lock included a housing, a lock body, and a control circuit device. An annular latch and the lock body are disposed in the housing. A back cover is configured to close the housing. The annular latch has a first engaging groove, a second engaging groove and a third engaging groove. The lock body includes a first baffle that can be engaged in the first engaging groove or the second engaging groove, a second baffle that can be engaged in third engaging groove, and a speed reduction motor having a lever. The lever includes an angle control block and an eccentric paddle. The control circuit device includes an induction unit and a key fob. The key fob is configured to generate induction with the induction unit for transmitting a signal. With the above configuration, the bicycle inductive lock can sense the signal to be locked or unlocked.
