Solution Overview
Problem
Conventional electronic thermometers require manual power-on and power-off operations, which can be inconvenient and lead to unnecessary power consumption during standby mode.
Innovation Solution
A temperature sensing device equipped with a detection unit, such as a pressing switch, G-sensor, ball rolling switch, or light sensor, that automatically powers on when picked up and powers off when stationary, eliminating the need for manual operation and reducing standby mode duration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual power-on operation is required, then device control is simple and reliable, but user convenience deteriorates and operation time increases
Solution Approach 1:
The detection unit automatically detects when the temperature sensing device is picked up or moved from a standing state, triggering the power-on process without requiring manual user operation. The device serves itself by autonomously determining when power-on is needed based on movement detection, eliminating the need for users to manually press power buttons while maintaining simple overall device architecture.
2Duration of action of moving object
If manual power-off operation is required, then power consumption control is simple, but standby time increases and battery life deteriorates
Solution Approach 1:
The detection unit continuously monitors the device state and automatically triggers power-off when the device remains in a standing state for a predetermined period. The system autonomously manages power consumption by detecting prolonged inactivity and shutting down without user intervention, extending battery life while avoiding complex manual power management interfaces.
Solution Approach 2:
The detection unit operates periodically to check whether the device is in a standing state for a predetermined period of time. This periodic monitoring enables automatic power-off decisions based on time-based criteria, reducing standby power consumption while maintaining simple control logic through regular state assessments.
3Loss of time
If automatic power-on is implemented, then user experience improves and operation time is reduced, but detection complexity increases
Solution Approach 1:
The patent replaces manual mechanical button pressing with an automatic detection system that senses device movement or changes in gravitational orientation. This substitution eliminates the need for users to physically press power buttons, reducing power-on waiting time while using straightforward motion or orientation sensing mechanisms rather than complex detection systems.
