Power Control Device for Receiving Units in Wireless Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for controlling receiving units fail to efficiently manage power consumption, leading to increased energy usage and inefficiency, particularly in devices like lamps and appliances that receive wireless or non-wireless operation control signals.
Innovation Solution
A system comprising a device that detects the state of an apparatus and controls the power supply of a receiving unit based on operation control signals, switching off the power supply when the apparatus is in a specific state and switching it back on when necessary, thereby reducing average power consumption.

Engineering Contradiction Analysis
1Speed
If the receiving unit remains continuously powered to ensure immediate response to control signals, then the response time is improved, but the power consumption increases
Solution Approach 1:
The receiving unit operates in periodic cycles, alternating between active reception mode and power-down mode. The controller periodically activates the receiving unit to check for new control signals, then deactivates it during idle periods. This periodic operation maintains the ability to respond to signals while significantly reducing average power consumption compared to continuous operation.
Solution Approach 2:
The system dynamically adjusts the power state of the receiving unit based on real-time conditions. The controller monitors whether new control signals are present and dynamically switches the receiving unit between powered and unpowered states accordingly. This dynamic control optimizes the balance between response capability and energy consumption.
2Use of energy by stationary object
If the receiving unit is switched off to reduce power consumption, then the average power consumption is improved, but the reliability of signal reception may deteriorate
Solution Approach 1:
The controller receives feedback about the presence of new control signals and uses this information to determine when to activate the receiving unit. This feedback mechanism ensures that the receiving unit is activated only when necessary, maintaining reliable signal reception while minimizing power consumption during idle periods.
Solution Approach 2:
The system performs preliminary checks to determine whether the receiving unit needs to be activated. The controller assesses whether new control signals are present before activating the receiving unit, preventing unnecessary activations and ensuring reliable reception only when needed.
3Productivity
If a hierarchical control system is implemented to manage multiple receiving units, then the overall system efficiency is improved, but the device complexity increases
Solution Approach 1:
The control system is segmented into hierarchical levels with each level managing specific receiving units. The controller at each level independently manages the power states of its subordinate receiving units, dividing the overall control complexity into manageable segments. This segmentation improves system efficiency through coordinated control while keeping individual device complexity acceptable.
Solution Approach 2:
The controller is designed with multi-functional capabilities, serving both as a power management device and as a signal reception controller. This universality reduces the need for separate dedicated components at each hierarchical level, thereby reducing overall system complexity while maintaining efficiency.
