Solution Overview
Problem
HDMI active optical cables face issues when connected to devices that do not support power supply, as they request more power than anticipated, leading to erroneous operations.
Innovation Solution
A connector device with a signal processor, switch, and movable member that authenticates power supply support and non-support devices, preventing connection to non-support devices by adjusting its position based on the switch state, ensuring appropriate power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the HDMI active optical cable requests more power to ensure stable transmission of high-definition video signal, then the transmission stability is improved, but it causes erroneous operation when connected to power supply non-support electronic devices
Solution Approach 1:
The connector device performs preliminary authentication of the electronic device's power supply capability before establishing full power transmission. The movable member is positioned in advance to either allow or block power transmission based on the authentication result, preventing erroneous operations before they can occur.
Solution Approach 2:
The movable member acts as an intermediary between the connector and the electronic device, controlling whether power is transmitted. It serves as a physical mediator that can block or allow power flow based on the authentication outcome, resolving the conflict between power requirements and device compatibility.
2Adaptability or versatility
If the connector device always allows power transmission to support all HDMI cables, then compatibility with all devices is improved, but it causes excessive power consumption and erroneous operations when connected to non-support devices
Solution Approach 1:
The connector device dynamically adjusts its power transmission state based on authentication results. The movable member can shift positions to either allow or block power transmission, making the system adaptable to different device types rather than having a fixed power transmission mode.
Solution Approach 2:
The connector device applies different power transmission characteristics to different connection scenarios. Through authentication, it identifies whether the connected device is a support or non-support device and applies the appropriate power transmission mode locally, rather than using a uniform approach for all connections.
3Measurement precision
If the connector device adds authentication functionality to distinguish support and non-support devices, then power management accuracy is improved, but the device complexity increases
Solution Approach 1:
The authentication functionality is extracted as a separate, dedicated mechanism within the connector device. The movable member and authentication circuitry are distinct components that specifically handle power capability detection, separating this function from the main connector structure and making the complexity manageable and focused.
4Reliability
If the movable member is positioned to block power transmission, then prevention of erroneous operations is improved, but connection to power supply non-support electronic devices is prevented
Solution Approach 1:
The movable member provides dynamic control over power transmission based on real-time authentication results. It can be positioned to block power transmission when connected to non-support devices while allowing transmission when connected to support devices, making the system both reliable and adaptable.
Solution Approach 2:
The system changes the power transmission parameter (blocked or allowed) based on the authentication outcome. The movable member physically implements this parameter change by shifting positions, enabling the connector to adapt its behavior to match the capabilities of the connected device.

AI summary
According to an embodiment, a connector device is connected to an electronic device. The connector device includes a signal processor, a switch, and a movable member. The signal processor processes a signal inputted from the electronic device or a signal outputted to the electronic device. The switch is ON when power supplied from the electronic device is used as a power supply for operating the signal processor. The movable member moves to a first position when the switch is ON and moves to a second position when the switch is OFF. The connector device is connectable to a power-supply-support electronic device and is not connectable to a power-supply-non-support electronic device when the movable member is at the first position. The connector device is connectable to the power-supply-support and power-supply-non-support electronic devices when the movable member is at the second position.
