Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart wearable devices often fail to meet a day's usage requirement on a single charge, limiting their convenience due to inadequate endurance capacity.
Innovation Solution
A power supply module combining a solar battery and a storage battery, with switch units and voltage stabilization components, allows the solar battery to supply power when irradiated and the storage battery to take over when light is insufficient, ensuring diversified power sources and extended device usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If only a storage battery is used to supply power, then the device structure is simple, but the endurance capacity is insufficient to meet one day's usage requirement
Solution Approach 1:
The patent combines a solar battery and a storage battery into a dual-power supply system. The solar battery converts light energy to electrical energy to extend the device's endurance capacity, while the storage battery provides stable power when light is insufficient. This merging of two power sources resolves the contradiction between extended duration and increased system complexity.
Solution Approach 2:
The power supply module is designed to perform multiple functions: the solar battery generates power from light energy during daytime, while both the solar battery and storage battery can supply power during nighttime or low-light conditions. This multi-functionality allows the system to meet one day's usage requirement by adapting to different environmental conditions.
2Adaptability or versatility
If the solar battery and storage battery are directly connected to the same output, then the power supply sources are diversified, but current may flow back and damage the batteries
Solution Approach 1:
The patent introduces diodes as intermediary components between the solar battery and storage battery outputs. These diodes act as one-way valves for current flow, allowing current to flow from each battery to the common output but preventing reverse current flow. This intermediary component enables diversified power sources while protecting against battery damage from reverse current.
Solution Approach 2:
The control unit monitors the voltage levels of both the solar battery and storage battery, and dynamically controls the switching between power sources. When the solar battery voltage is sufficient, it supplies power; when insufficient, the storage battery takes over. This feedback mechanism ensures reliable operation and prevents harmful current flow conditions.
