Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power control devices cannot detect abnormal inclined positions of electric devices, leading to continuous power supply and increased accident risk, and fail to differentiate between normal and inappropriate use states.
Innovation Solution
A power control device with a multi-directional sensor switch and control circuit that determines the position and use state of an electric device, outputting power-supply or power-off signals to control the electric power switch accordingly, ensuring safe and appropriate power distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional sensor switch is used to detect use position, then the device can detect normal use position, but it cannot detect abnormal inclined positions
Solution Approach 1:
The sensor switch is divided into multiple sensing elements arranged in specific directions. Each sensing element detects inclination in a particular direction, and their combined output determines the overall position state (normal use position vs. abnormal inclined position) of the electric device.
Solution Approach 2:
The sensor switch transitions from detecting only vertical position (one dimension) to detecting multi-directional inclination (multiple dimensions). By adding directional sensing capabilities, the system can identify abnormal inclined positions that were previously undetectable.
2Adaptability or versatility
If a conventional sensor switch is used, then the structure remains simple, but the device cannot differentiate between normal and inappropriate use states
Solution Approach 1:
The sensor switch is designed to perform multiple functions: detecting normal use position, detecting abnormal inclined positions, and differentiating between normal and inappropriate use states. This multi-functional sensor reduces the need for multiple separate detection systems.
Solution Approach 2:
The sensor switch acts as an intermediary device that translates physical position and orientation information into electrical signals. The control unit then processes these signals to determine the appropriate power supply state, separating the sensing function from the control decision-making.
3Reliability
If the conventional sensor switch fails to detect abnormal positions, then the device structure remains simple, but power is continuously supplied increasing accident risk
Solution Approach 1:
The sensor switch provides continuous feedback about the electric device's position and orientation to the control unit. Based on this feedback, the control unit automatically adjusts the power supply state, cutting off power when abnormal inclined positions are detected and enabling power when normal use positions are detected.
Solution Approach 2:
The sensor switch and control unit are configured to detect abnormal positions before accidents can occur. The system proactively cuts off power supply when potential safety hazards are detected, preventing rather than merely responding to dangerous situations.

AI summary
A power control device includes an electric power switch and a control unit. The control unit is mounted on an electric device, determines whether the electric device is disposed at a normal use position or an abnormal inclined position, and determines whether the electric device is at a normal use state and is disposed at the normal use position. The control unit controls the electric power switch to provide electric power to the electric device when the electric device is at the normal use state, and to stop providing the electric power to the electric device when the electric device is at the abnormal inclined position.
