Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart wearable devices, such as smart watches, have a markedly insufficient standby time, requiring daily or even hourly charging, which is inconvenient for users and falls short of providing convenience in daily life.
Innovation Solution
The smart watch design incorporates a battery within the watch frame and a flexible stand-by battery in the watchband, with sub-batteries evenly distributed and electrically connected, and optionally includes a flexible solar battery in a transparent watchband to extend battery life, along with sensor units and an energy transformation unit to harness motion energy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a single battery is used in the watch frame, then the device structure is simple, but the standby time is insufficient
Solution Approach 1:
The battery system is divided into multiple sub-batteries distributed in the watch frame and a stand-by battery in the watchband. Each sub-battery is electrically connected through wires, creating a segmented power system that increases total capacity while maintaining manageable complexity through modular architecture.
2Quantity of substance
If multiple sub-batteries are distributed in the watch frame, then the battery storage capacity increases, but the device complexity increases
Solution Approach 1:
Multiple sub-batteries are nested within the watch frame structure, with each sub-battery positioned in available spaces. The wires connecting these sub-batteries are routed through the watch frame, creating a compact nested arrangement that maximizes space utilization while maintaining organizational simplicity.
3Duration of action of moving object
If a flexible solar battery is added to the watchband, then the standby time is extended, but the device complexity increases
Solution Approach 1:
The watchband serves multiple functions: it provides structural support, houses the stand-by battery, and incorporates the flexible solar battery for energy generation. This multi-functional design extends battery life through diverse power sources while avoiding the complexity of separate dedicated components for each function.
4Use of energy by moving object
If the watchband is made transparent to accommodate solar battery, then the energy generation capability is improved, but the aesthetic appearance may be affected
Solution Approach 1:
The watchband is constructed from flexible transparent material that allows light transmission to the solar battery while maintaining structural integrity. This thin-film approach enables energy generation without significantly compromising the visual appearance, as the transparency minimizes the visual impact of the solar battery integration.
