Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable electronic devices such as smart watches and smart glasses experience downtime due to lengthy battery charging times, during which they cannot be used for their intended functions, as their embedded batteries cannot be easily swapped or recharged.
Innovation Solution
A quick release and connect system that allows attachable/detachable auxiliary components with embedded auxiliary batteries to be swapped with the main battery, providing power through electro-mechanical connectors, and a method to detect low power levels and automatically transfer charge from auxiliary batteries to the main battery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the battery is embedded within the wearable device, then the device structure is compact and integrated, but the battery cannot be easily swapped and charging time is lengthy
Solution Approach 1:
The battery system is divided into two independent parts: an embedded main battery within the device head and separate auxiliary batteries within detachable components. This segmentation allows the auxiliary batteries to be quickly swapped independently without affecting the main device structure, resolving the contradiction between integration and swapability.
Solution Approach 2:
The auxiliary batteries are extracted from the main device body and placed in detachable components that can be quickly removed and replaced. This extraction enables rapid battery swapping to reduce charging downtime while the main embedded battery remains in place for continuous operation.
2Volume of moving object
If the battery is embedded within the wearable device, then the device is compact, but the device cannot be used during battery charging
Solution Approach 1:
Auxiliary batteries are pre-charged and stored in detachable components before being needed. When the main battery requires charging, users can quickly swap in pre-charged auxiliary batteries, ensuring continuous device availability without waiting for charging.
Solution Approach 2:
The system enables continuous operation by allowing auxiliary batteries to provide power during transitions. The dual battery configuration ensures that while one battery is charging, the other can maintain device operation, eliminating downtime and maintaining continuous productivity.
3Loss of time
If auxiliary components with auxiliary batteries are added, then battery swapping is enabled and downtime is reduced, but device complexity increases
Solution Approach 1:
The detachable components serve multiple functions: they house auxiliary batteries for power supply, contain electro-mechanical connectors for automatic connection, and act as wearable components themselves. This multi-functionality reduces the need for separate systems and minimizes overall complexity.
Solution Approach 2:
The auxiliary battery, connector, and detachable component are merged into a single integrated unit. This combination simplifies the swapping operation to a single action while providing multiple functions (power supply, connection, and wearability), thereby reducing operational complexity despite adding functionality.
4Extent of automation
If electro-mechanical connectors are used to connect auxiliary components, then automatic power transfer is enabled, but manufacturing complexity increases
Solution Approach 1:
The electro-mechanical connector acts as an intermediary that automatically establishes electrical connection when auxiliary components are attached. This intermediary enables seamless power transfer without complex control systems, simplifying manufacturing while maintaining automation.

Function Achieved in This Case
Significantly reduces downtime by allowing quick swapping of auxiliary batteries, enabling continuous use of wearable devices with minimal interruption, as the auxiliary batteries can power the device while the main battery is being recharged.
