Remote Controller Dual Power Supply Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional remote controllers with single power supply units face frequent battery depletion due to high power consumption of advanced control units, leading to frequent battery replacements and operational failures, especially when less frequently used high-power functions deplete the battery, rendering fundamental low-power functions inoperable.
Innovation Solution
A remote controller with dual power supply units, where a first sub-system with low power consumption handles fundamental operations and a second sub-system with higher power consumption handles advanced functions, with the first sub-system being extremely power-saving and the second sub-system powered by a separate unit that can include a rechargeable device to extend its power supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single power supply unit is used to power all control units, then the device complexity is reduced, but the reliability deteriorates because power depletion renders the entire remote controller inoperable
Solution Approach 1:
The power supply system is segmented into two independent units: a first power supply unit powering the button module and infrared transmitting module, and a second power supply unit powering the acoustic control module, touch control module, and sensing unit. This segmentation ensures that depletion of one power supply does not affect the operation of the other, maintaining partial functionality and improving reliability.
2Adaptability or versatility
If high-power control units are added to support diversified functions, then the adaptability is improved, but the use of energy increases causing frequent battery depletion
Solution Approach 1:
Control functions are segmented into low-power frequently-used functions (button control, infrared transmission) and high-power less-frequently-used functions (acoustic control, touch control, sensing). The first power supply unit handles low-power functions with basic batteries, while the second power supply unit handles high-power functions with rechargeable batteries, optimizing energy usage across different function types.
Solution Approach 2:
Different power supply configurations are applied to different control modules based on their specific power consumption characteristics and usage frequency. The button module and infrared transmitter use basic batteries optimized for long-duration low-power operation, while the acoustic, touch, and sensing modules use rechargeable batteries capable of handling higher power demands.
3Ease of operation
If basic batteries are used in the first power supply unit, then the ease of operation is improved for frequent functions, but the duration of action is limited compared to rechargeable units
Solution Approach 1:
The battery system is segmented into basic batteries for the first power supply unit and rechargeable batteries for the second power supply unit. This segmentation allows users to easily replace basic batteries when depleted (improving ease of operation for frequent low-power functions) while the rechargeable batteries provide extended operational life for high-power functions that are used less frequently.

AI summary
A remote controller with dual power supply units is provided. The remote controller controls an electronic apparatus. The remote controller includes a housing, a first sub-system and a second sub-system. The first sub-system is disposed in the housing and includes a first power supply unit for powering the first sub-system. The first sub-system further generates a first signal for controlling the electronic apparatus to perform a first operation. The second sub-system is disposed in the housing and includes a second power supply unit for powering the second sub-system. The second sub-system further generates a second signal for controlling the electronic apparatus to perform a second operation.
