Connector Detecting Mechanism for Energy Conservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Connectors with SPDIF interfaces, commonly used in digital audio and video equipment, consume power even when an external device is not connected, leading to inefficient energy usage.
Innovation Solution
A connector design featuring a detecting mechanism with breakover, powering, and grounding pins, along with an elastic door mechanism and LED indication, that only powers up when an external device is connected, utilizing a control module to manage power supply and conserve energy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the connector is powered on at all times to ensure plug and play functionality, then the ease of operation is improved, but the use of energy increases
Solution Approach 1:
The connector performs preliminary detection through the detecting portion to check if an external device is connected before activating the powering pin to supply power. This preliminary action ensures that power is only consumed when needed, resolving the contradiction between always being ready for plug-and-play operation and conserving energy when no device is connected.
Solution Approach 2:
The detecting portion continuously monitors the connection status and provides feedback to the control system. When a device is detected, the system activates power supply; when no device is present, power is cut off. This feedback mechanism maintains operational readiness while preventing unnecessary energy consumption.
2Use of energy by moving object
If the detecting mechanism is added to detect external device connection, then the use of energy is reduced, but the device complexity increases
Solution Approach 1:
The detecting portion is integrated directly into the connector structure, merging the detection function with the existing connector components. The detecting portion works in conjunction with the breakover pin, powering pin, and grounding pin as a unified system, reducing overall complexity compared to having separate detection and connection mechanisms.
Solution Approach 2:
The detecting portion serves multiple functions: it detects external device connection, triggers the breakover mechanism, and controls power supply activation. This multi-functionality reduces the need for separate components, thereby minimizing the increase in device complexity while achieving energy conservation.

AI summary
A connector includes a cavity, a detecting portion, and a door. The cavity includes a first interface, the detecting portion is set in the cavity, and the door is set at the first interface. A first door first end includes a metal portion, such that when an external device enters in the cavity through the first interface by pushing the door, the metal portion is coupled to the detecting portion, and the detecting portion outputs a first control signal accordingly. When an external device is inserted into the connector, a power is supplied to the connector, when the external device is not inserted into the connector, the power is not supplied to the connector, thus achieving the purpose of energy conservation.
