Solution Overview
Problem
Conventional electronic thermometers require manual operation for power-on and power-off, and initiating temperature measurement, which can be inconvenient and time-consuming, especially when trying to quickly measure body temperature.
Innovation Solution
A temperature sensing device with a detection unit that automatically switches modes based on user interaction, such as picking up or shaking the device, allowing for automatic power-on and initiation of temperature measurement without manual button pressing, utilizing a control unit, power supply unit, and power circuit with touch and shake sensing circuits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual power-on operation is used, then device control is simple and reliable, but user operation time and complexity increase
Solution Approach 1:
The detection unit continuously monitors whether the device is in a standing state before user interaction occurs. When the device is picked up from the stand, the system is already prepared to automatically initiate power-on sequence, eliminating the need for manual button pressing and reducing power-on time.
Solution Approach 2:
The device automatically detects its own state (standing or moved) and autonomously initiates the power-on process without requiring user intervention. The control unit receives detection signals and automatically executes power-on commands, making the system self-activating based on physical state changes.
2Ease of operation
If automatic power-on is implemented, then user operation is simplified, but device complexity increases
Solution Approach 1:
The power control functionality is segmented into independent modules: a detection unit for state monitoring, a control unit for decision-making, and a power supply unit for power management. This modular segmentation allows automatic power-on functionality to be added without significantly complicating the overall device structure, as each module performs a specific function.
3Productivity
If manual mode switching is used, then power consumption is controlled, but productivity decreases
Solution Approach 1:
The device operates in periodic cycles: when placed on the stand, it enters a low-power standby mode; when picked up, it automatically activates for temperature measurement; after measurement, it returns to standby. This periodic activation pattern enables quick temperature measurements while conserving battery power during extended idle periods.
