Solution Overview
Problem
Wall-mounted display devices require secure and safe power supply solutions to prevent accidental electric shocks, especially as they become thinner and lighter, and existing technologies lack effective mechanisms for automatic power connection and disconnection.
Innovation Solution
A power supply socket with a conductive member, switching element, and control component that detects the power receiving head using light detection and magnetic fields to control the switching element's on/off state, ensuring power supply only when the head is properly connected and disconnecting when not, thereby preventing accidental electric shocks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If wall-mounted display devices are made thinner and lighter, then the device portability and installation flexibility are improved, but the risk of accidental electric shocks increases due to improper power connection
Solution Approach 1:
The control component performs preliminary detection to determine whether the power receiving head is properly connected before enabling power supply. The switching element is controlled to be in the off state initially, and only transitions to on state after successful detection, preventing accidental electric shocks before they can occur
Solution Approach 2:
The switching element serves as an intermediary component between the power supply and the power receiving head. It mediates the power transmission by being controlled based on detection results, ensuring that power is only supplied when proper connection is confirmed, thus reducing electric shock risk
2Object-affected harmful factors
If automatic power connection and disconnection mechanisms are added, then user safety is improved, but the device complexity increases
Solution Approach 1:
The power supply socket achieves automatic power connection and disconnection through self-service mechanisms. The control component automatically detects connection status and controls the switching element accordingly, eliminating the need for manual intervention while maintaining simple overall structure
Solution Approach 2:
The control component establishes a feedback loop by continuously monitoring the connection status of the power receiving head and adjusting the switching element state accordingly. This automatic feedback mechanism ensures safety without requiring complex manual control systems
