Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If portable devices use disposable batteries, then the batteries can be simply replaced with new ones, but the device lacks means to detect the charge status of the batteries
Solution Approach 1:
The patent introduces a separate testing device as an intermediary tool that connects to the portable device through a USB port. This testing device contains the necessary circuitry and processing units to detect battery charge status, acting as a mediator between the simple disposable battery system and the need for charge status information. The testing device can identify battery type, voltage, and charge status without modifying the portable device itself.
2Duration of action of stationary object
If rechargeable batteries are used in portable devices, then the batteries can be reused, but the device may not have the circuitry to check the status of the battery
Solution Approach 1:
The patent extracts the battery status detection functionality from the portable device itself and places it in a separate, dedicated testing device. This allows the portable device to maintain its simplicity while still being able to check battery status through the external testing device connected via USB. The testing device contains all necessary circuitry for voltage measurement, battery type identification, and charge status determination.
3Adaptability or versatility
If multiple batteries are used in a device, then the device can operate with different battery types, but it becomes difficult to separate good batteries from bad batteries
Solution Approach 1:
The testing device provides comprehensive feedback about battery health status through multiple measurement parameters including voltage, battery type identification, and charge status. The system can distinguish between healthy and depleted batteries by analyzing these parameters, providing clear feedback to users about which batteries are functional and which need replacement, thereby solving the difficulty of separating good batteries from bad ones.
Data Source
AI summary
A system for determining the charge status of a battery to check whether the battery is healthy or dead. The system includes a probe to measure one or more parameters of the battery, such as voltage. The system further includes a user device configured to receive measured values from the probe. The user device includes an interface module and a control module. An interface rendered by the interface module can receive specifications of the battery and present the charge status. The control module can analyze the measured values of different parameters with reference to the specifications of the battery.
