Solution Overview

Problem

Conventional bicycle locks are inconvenient to use as they require traditional key-based locking and unlocking mechanisms.

Innovation Solution

An electronic control lock system for bicycles that includes an electronic controller, a kickstand lock with a stand control device, and a frame lock, allowing for wireless or wired signal connection, and features a stand engaging element, a resilient element, and an operating element controlled by the electronic controller to manage the kickstand's rotation and locking states.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a conventional key-based lock is used for the bicycle kickstand, then the locking mechanism is simple and reliable, but the ease of operation deteriorates due to the inconvenience of using traditional keys

Engineering Contradiction:
Improveease of operationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces the traditional mechanical key-based locking system with an electronic control system. The electronic controller receives signals (e.g., via mobile device communication) and controls the stand operating element to lock or unlock the kickstand, eliminating the need for physical keys and improving operational convenience.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces an electronic controller as an intermediary between the user and the kickstand locking mechanism. The controller processes signals from external devices (such as smartphones) and translates them into mechanical actions through the stand operating element, enabling remote and contactless locking operations.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If an electronic control system is added to the kickstand lock, then the ease of operation improves by eliminating traditional keys, but the device complexity increases due to additional electronic components

Engineering Contradiction:
Improveease of operationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The electronic controller serves multiple functions: it receives unlocking signals from external devices, controls both the frame lock and kickstand lock, and can interface with alarm systems. This multi-functionality justifies the added complexity by consolidating control operations into a single intelligent unit.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system enables self-service operation where the kickstand automatically locks when flipped down and unlocks when an electronic signal is received. The stand resilient element and stand operating element work together to automatically engage and disengage the locking mechanism without requiring manual intervention beyond triggering the electronic signal.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If the kickstand is made rotatable with flip-down and kicked-up states, then the adaptability improves for different usage scenarios, but the reliability deteriorates as the moving part can be accidentally kicked up

Engineering Contradiction:
ImproveadaptabilityVSAvoidreliability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies preliminary anti-action by implementing an electronic locking mechanism that prevents the kickstand from being accidentally kicked up. The stand operating element, controlled by the electronic controller, blocks the rotation path of the kickstand when in the locked state, countering any unintended upward movement before it can occur.

Inventive Principle:
Principle #9Preliminary anti-action

Solution Approach 2:

The system performs preliminary action by automatically locking the kickstand in the flipped-down position through the stand resilient element and stand engaging element mechanism. This preliminary locking action ensures the kickstand remains secure before any user interaction occurs, preventing accidental displacement.

Inventive Principle:
Principle #10Preliminary action

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 convenient electronic locking and unlocking of the kickstand and frame lock without traditional keys, providing enhanced security and ease of use by allowing the kickstand to remain in a locked position until electronically unlocked, and featuring automatic locking functions and alarm notifications.

Implementation Method 1

The stand resilient element tends to force the stand engaging element to engage with the kickstand, so as to stop the kickstand from rotating

AI summary

An electronic control lock of a bicycle has an electronic controller (10), a kickstand lock (20), and a frame lock (30). The kickstand lock (20) includes a kickstand (21) and a stand control device (22). When locking, the stand control device (22) stops the kickstand (21) from being kicked up. The frame lock includes an inserting element (32) and a frame control device (33). When locking, the frame control device (33) makes the inserting element (32) unable to be pulled out. Thus the inserting element (32) can fasten the bicycle with a chain. When unlocking, the stand control device (22) and the frame control device (33) are controlled by the electronic controller (10), to allow the kickstand (21) being kicked up and the inserting element (32) being pulled out.
