Temperature Controlled Mouse Activation via Thermal Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional optical mice waste energy due to accidental activation and prolonged illumination, lacking efficient operation status management, leading to unnecessary power consumption.
Innovation Solution
A temperature-controlled mouse that uses a temperature control circuit to detect hand temperature and adjust its operation status, activating only when within a predetermined temperature range (25° C to 35° C), thereby preventing accidental activation and entering power-saving mode when not in use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the mouse is activated by touch to enable operation, then the mouse can be controlled, but the mouse remains illuminated and consumes power even after the user's hand leaves
Solution Approach 1:
The patent changes the activation parameter from simple touch detection to temperature range detection. The mouse remains in sleep mode unless a hand with body temperature (25°C to 35°C) is detected, which automatically activates it. This resolves the contradiction by using temperature as a more specific activation criterion that distinguishes intentional use from accidental contact.
2Reliability
If the mouse stays in operation mode for extended time, then the mouse remains responsive to control, but energy is wasted continuously
Solution Approach 1:
The patent implements periodic temperature monitoring to determine when to switch between sleep and operation modes. The mouse continuously monitors temperature and automatically transitions states based on detected changes, creating a periodic check-in mechanism that ensures responsiveness while minimizing power consumption during idle periods.
3Ease of operation
If the mouse is awakened by accidental touch, then the mouse becomes operational, but it cannot distinguish between intentional and unintentional activation
Solution Approach 1:
The patent introduces temperature detection as an intermediary parameter between physical contact and mouse activation. Instead of directly activating on touch, the system first detects the thermal signature of a hand, which serves as a mediator to infer intentional use. This resolves the information loss by providing additional contextual data about user intent.

AI summary
A temperature controlled mouse includes a central controller, a driver control circuit, a temperature control circuit, and a signal transmitting circuit. The driver control circuit generates coordinate control signals and pointer clicking signals, and the signals are transmitted to a host computer coupled to the mouse via the signal transmitting circuit. The temperature control circuit detects the changes of the temperature from a user's hand and thereby generates temperature control signals. The central controller controls the operation status of the mouse according to the temperature control signals, wherein when the temperature detected is within a predetermined temperature range, the central controller wakes the mouse and allows the transmission of signals from the mouse to the host computer; otherwise the central controller stops the transmission of signals. The temperature controlled mouse prevents accidental activation due to negligent bump. Thereby the mouse may only wake from purposeful control and thereby conserves energy.
