E-Bike Battery Activation Sensor for Sealed Housing Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric bicycle batteries require a push-button for activation in the disassembled state, which necessitates electrical passages through the housing, potentially leading to moisture ingress and design constraints.
Innovation Solution
The electric bicycle battery incorporates an activation sensor within the housing, eliminating the need for a push-button. This sensor detects activation operations such as movement, contact, or illumination, allowing the battery to be activated in a detached state without external power or operating units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a push-button is used for battery activation, then the battery can be switched on in the disassembled state, but electrical passages through the housing are required which create potential moisture entry points and design constraints
Solution Approach 1:
The push-button component is completely removed from the system. Instead, an activation sensor is integrated within the housing that detects activation operations (such as contact or movement) without requiring any openings or passages through the housing, thus eliminating the moisture ingress risk while maintaining activation functionality
Solution Approach 2:
The mechanical push-button system is replaced with an electronic activation sensor system. The sensor detects activation operations through non-contact or minimal-contact means, substituting the mechanical button press with an electronic detection mechanism that does not require openings in the housing
2Ease of operation
If a push-button is used for battery activation, then the battery can be switched on in the disassembled state, but the housing design is constrained by the need to accommodate the button and its mounting
Solution Approach 1:
The push-button component and its mounting structure are completely removed from the housing design. The activation sensor is integrated directly into the housing or circuit board without requiring separate button assemblies, mounting holes, or adhesive foil structures, thereby simplifying the overall housing design and reducing structural constraints
Solution Approach 2:
The activation sensor is merged with the housing structure or circuit board, eliminating the need for separate button components and their associated mounting structures. This integration reduces the number of parts and simplifies the housing design while maintaining the activation functionality
3Ease of operation
If a push-button is used for battery activation, then the battery can be switched on in the disassembled state, but a comparatively large amount of installation space is required for the connector and circuit board arrangement
Solution Approach 1:
The external push-button connector and its associated circuit board arrangements are removed. The activation sensor is integrated directly into the existing circuit board within the housing, eliminating the need for additional connectors, adhesive foils, and cable passages, thereby reducing the overall installation space requirements
