Accumulated Temperature Power Control for Low-Temperature Burn Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric power control techniques for devices like mobile phones fail to prevent low-temperature burns without compromising user convenience, as they either limit temperature thresholds too low, require specific touch sensor interactions, or incorrectly detect temperature rises during digital recording functions, leading to false warnings.
Innovation Solution
An electric power control apparatus that detects device temperatures, accumulates numerical values associated with these temperatures, and reduces or stops power supply when the accumulated value exceeds a preset threshold, thereby reducing the load on the user and preventing low-temperature burns without sudden power cessation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a temperature threshold is lowered to prevent low-temperature burns, then safety is improved, but user convenience deteriorates because even short-time operations without risk are limited
Solution Approach 1:
The system performs preliminary temperature monitoring and accumulation before triggering power control. By accumulating temperature values over time and comparing against a threshold, the system predicts potential burn risks in advance, allowing normal operation during safe conditions while preventing burns when risk accumulates
Solution Approach 2:
The patent implements dynamic temperature control by switching between normal operation mode and temperature control mode based on accumulated temperature values. The control threshold is not fixed but adapts based on the accumulation rate and current temperature state, allowing flexible response to different operational scenarios
2Measurement precision
If a touch sensor section is used to detect human body contact, then control accuracy is improved, but coverage deteriorates because only the touch sensor section can be detected
Solution Approach 1:
The patent makes the entire device surface functional for temperature detection, not just a specific touch sensor section. Any part of the device that contacts the user's body can contribute to the temperature accumulation, making the system universally responsive to user contact regardless of location
3Reliability
If temperature monitoring is continuously performed to detect sealed environment placement, then detection capability is improved, but false warnings increase when digital recording functions cause temporary temperature rises
Solution Approach 1:
The system uses partial temperature accumulation rather than immediate threshold triggering. By accumulating temperature values over multiple measurement cycles and requiring the accumulated value to exceed the threshold, the system filters out temporary temperature spikes from digital recording while still detecting sustained temperature rises from sealed environment placement

AI summary
An electric power control section includes: a temperature detecting section for detecting temperatures of a battery; and an accumulation counter for accumulating numerical values assigned to the respective temperatures of the battery which have been detected by the temperature detecting section. The electric power control section reduces electric power supply to an LCD display section when an accumulated value obtained by the accumulation counter exceeds a preset value.
