Remote Control Sensor Power Management via Selective Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional remote controls with multiple sensors for pointing operations experience high battery consumption due to the need for continuous sensor activation, reducing user convenience.
Innovation Solution
A remote control system that selectively turns on/off sensors based on movement detection by one primary sensor, using an analog to digital converter and transmission unit to send signals to an image display apparatus without algorithmic processing, thereby reducing battery consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple sensors are continuously activated for remote pointing operations, then the remote control can accurately sense movement and control the pointer, but battery consumption increases significantly
Solution Approach 1:
The patent implements periodic sensing by having the control unit selectively turn on sensors only when movement is detected by the primary sensor, rather than keeping all sensors continuously active. This periodic activation reduces battery consumption while maintaining accurate movement sensing capability when needed.
Solution Approach 2:
The patent divides the sensing function into a primary sensor that continuously monitors and multiple secondary sensors that are activated only when needed. This segmentation allows the system to maintain basic monitoring capability while reducing overall sensor activation and energy consumption.
2Adaptability or versatility
If multiple sensors are activated to enable remote pointing operation, then the remote control functionality is enhanced, but the complexity of the remote control increases
Solution Approach 1:
The patent merges the control of multiple sensors under a single control unit that manages activation based on movement detection. This consolidation simplifies the system architecture by having one intelligent controller manage multiple sensors rather than requiring separate control circuits for each sensor.
Solution Approach 2:
The control unit serves multiple functions: it processes signals from the primary sensor, determines when movement occurs, and controls the activation of secondary sensors. This multi-functionality reduces the need for separate dedicated components and simplifies the overall system.

AI summary
A remote control is provided including a plurality of sensors which sense movement of the remote control, and a control unit which turns on at least one sensor of the plurality of sensors and thereby senses movement of the remote control, and determines whether to turn on or off the remaining sensors according to whether or not the at least one sensor senses movement of the remote control. Consequently, battery consumption is reduced.
