Removable Battery Pack for Secure Bicycle Activity Tracker
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a data collection system for human-powered transportation vehicles like bicycles that is both secure and discreet to prevent theft, while also allowing for easy data tracking and synchronization without drawing attention to the vehicle.
Innovation Solution
An activity tracker that can be securely attached to a bicycle using standardized mounting holes or zip ties, featuring a removable battery pack for charging and a built-in pedal cadence sensor, allowing data to be transmitted wirelessly to a user's phone or cloud, and includes a design that blends seamlessly with the bicycle's frame to minimize theft risk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the data collection device is securely attached to the bicycle, then the security against theft is improved, but the device becomes more noticeable and may attract thieves
Solution Approach 1:
The device uses different visual characteristics for different parts: the main housing is black to blend with typical bicycle frames, while the removable battery pack is a contrasting color for easy identification and removal. This local differentiation allows the device to be secure yet selectively noticeable.
Solution Approach 2:
The battery pack is extracted as a separate, removable component from the main device housing. This allows the battery to be easily removed for charging without removing the entire device from the bicycle, maintaining security while enabling convenient maintenance.
2Object-affected harmful factors
If the device is made discrete to avoid attracting thieves, then theft risk is reduced, but ease of operation for charging and data synchronization becomes more difficult
Solution Approach 1:
The device is segmented into a permanent main housing that remains attached to the bicycle and a removable battery pack. The battery pack can be easily detached and reattached, providing convenient access for charging while keeping the main device secure on the bicycle.
Solution Approach 2:
The battery pack transition from static to dynamic - it can be removed and reattached as needed. This dynamic design allows the battery to be accessed for charging without permanently altering the device's mounted position or security configuration.
3Ease of operation
If the entire device is removed from the bicycle for charging, then charging access is improved, but security is compromised and the device is more vulnerable to theft
Solution Approach 1:
The device is divided into two functional segments: the main housing containing electronics and sensors that remains mounted on the bicycle, and the battery pack that can be independently removed for charging. This segmentation enables charging access without compromising the security of the main device.

AI summary
An activity tracker includes a device that includes a sensor component, a radio, a housing, and a removable portion. The sensor component is configured to obtain bicycle route information based on one or more sensors. The radio is configured to wirelessly communicate the bicycle route information to a remote computing device. The housing includes at least a portion of the sensor component and the radio. The removable portion includes a battery. The removable portion and the housing, when coupled, create a watertight seal to protect electronic components of the device.
