Wearable Device Detachable Power Strap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable electronic devices, such as smartwatches, have limited battery capacity due to size constraints, requiring frequent charging and limiting their usage scope when the battery module needs to be charged.
Innovation Solution
A detachable power supply strap with a second battery module and connector system that can be quickly connected and disconnected from the electronic assembly, allowing for extended usage without charging limitations and enabling the device to be worn on any part of the body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the battery module size is decreased to fit the wearable device, then the device size constraint is satisfied, but the using time is shortened and charging frequency increases
Solution Approach 1:
The power supply system is segmented into a built-in battery module within the electronic assembly and a detachable power supply strap with its own battery module. This segmentation allows the wearable device to have a small internal battery for portability while using an external expandable power source when needed, resolving the contradiction between small device size and extended usage time.
2Volume of moving object
If the battery module is made smaller to meet device size limits, then the wearable device fits better, but charging must occur more frequently
Solution Approach 1:
The power supply strap can be charged in advance independently of the electronic assembly. When the built-in battery is depleted, the pre-charged power supply strap can be quickly attached to provide power, eliminating the need for frequent charging cycles and reducing time loss.
3Quantity of substance
If the electronic meter is connected to a power supply to charge the battery module, then the charge capacity is increased, but the using scope is limited
Solution Approach 1:
The power supply system transitions from a static built-in battery to a dynamic configuration where the detachable power supply strap can be attached or removed based on usage needs. This dynamic design allows the device to adapt between different usage scenarios - wearing the device continuously with the strap for extended power, or removing the strap when not needed, thereby expanding the using scope.
Solution Approach 2:
The detachable power supply strap serves multiple functions: it extends power capacity when attached, and can be removed when not needed, allowing the device to be worn in various situations. The universal connector design enables compatibility and flexibility in different wearing scenarios, enhancing adaptability.
4Duration of action of moving object
If a detachable power supply strap with connector system is used, then usage time is extended and versatility is improved, but device complexity increases
Solution Approach 1:
The connector system and power supply strap are extracted as a separate detachable module from the main electronic assembly. This extraction allows the complex charging and power transfer mechanisms to be isolated in the strap, keeping the main device simple while still providing extended usage time through the optional attachment.
