Solution Overview

Problem

Existing bicycle components with electrical switches rely on external power supplies, which can be inconvenient and may not provide reliable power, and the integration of rechargeable power sources is often cumbersome and difficult to maintain.

Innovation Solution

A bicycle component featuring a rechargeable power source that can be charged externally and detachably attached, with an electrical switch activated by this power source, and a holding structure for secure attachment, along with features like a power source cover and electrical terminal structure for easy coupling and removal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a rechargeable power source is integrated into the bicycle component, then power supply reliability is improved, but device complexity increases

Engineering Contradiction:
Improvepower supply reliabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The power source is divided into a rechargeable battery unit and a separate holding structure. The battery can be independently removed and recharged externally, while the holding structure remains integrated with the bicycle component. This segmentation reduces the complexity of the main device while maintaining reliable power supply through the detachable rechargeable unit.

Inventive Principle:
Principle #1Segmentation

2Ease of repair

If the rechargeable power source is detachably attached, then ease of maintenance is improved, but connection reliability may worsen

Engineering Contradiction:
Improveease of maintenanceVSAvoidconnection reliability
Core Design Contradiction:
Ease of repairVSReliability

Solution Approach 1:

The rechargeable power source is extracted as a separate, detachable component from the main bicycle component. This allows the battery to be easily removed for recharging or replacement without disassembling the entire device, significantly improving maintenance ease while the holding structure ensures reliable reconnection.

Inventive Principle:
Principle #2Taking out (Extraction)

3Ease of operation

If an electrical terminal structure is added for electrical coupling, then ease of operation is improved, but device complexity increases

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

Solution Approach 1:

The electrical terminal structure is merged with the holding structure, so that the same component that physically holds the rechargeable power source also provides the electrical connection. This integration allows the battery to be easily inserted and removed while automatically establishing or breaking the electrical circuit, improving ease of operation without requiring separate connection mechanisms.

Inventive Principle:
Principle #5Merging (Combining)
