Display Tap Control for Connector Receptacle Position Indication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Passengers in vehicles face difficulty finding connector receptacles like USB and HDMI ports, especially when they are not directly visible or located at peripheral or recessed positions, leading to potential distractions, awkward movements, and safety risks due to inadequate illumination.
Innovation Solution
A control unit that receives tap information on a display and responds by showing a graphic indicating the position of the connector receptacle, which can be an X-ray or fluorescence graphic, allowing users to easily locate the connectors without illuminating the entire display, and optionally uses time-of-flight sensors and cameras to overlay hand motion for guidance and provide connection feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If connectors are illuminated to help passengers find them, then visibility of connectors is improved, but passenger distraction and safety risks increase
Solution Approach 1:
The patent applies local quality by illuminating only the specific connector area that needs to be found, rather than illuminating the entire display or cabin. The control unit activates illumination at the precise location of the connector receptacle, providing just enough light for visibility without creating widespread distraction. This localized approach resolves the contradiction by maintaining connector visibility while minimizing harmful distraction effects.
Solution Approach 2:
The patent introduces an intermediary guidance mechanism (visual indicators or arrows on the display) that mediates between the need for connector visibility and the need to avoid distraction. Instead of directly illuminating the connector which may cause distraction, the system first displays guidance information on the display screen to guide passengers to the connector location, then only illuminates the connector area if needed. This intermediary step reduces direct visual distraction while still solving the visibility problem.
2Adaptability or versatility
If connectors are placed at peripheral or recessed positions to optimize display design, then display functionality is improved, but connector accessibility and ease of operation deteriorate
Solution Approach 1:
The patent applies feedback by providing real-time visual information on the display screen that indicates the location of connector receptacles. The control unit receives information about connector positions and displays corresponding visual indicators (such as icons or arrows) that guide passengers to the correct location. This feedback mechanism compensates for the reduced accessibility caused by peripheral or recessed connector placement, allowing passengers to easily locate connectors even when they are not directly visible or require awkward movements to reach.
3Illumination intensity
If the display remains dark to maintain viewing quality, then display performance is improved, but connector location detection becomes difficult
Solution Approach 1:
The patent applies periodic action by activating display illumination or connector indicators only at specific moments when connector location information is needed, rather than maintaining continuous illumination. The control unit monitors for user requests (such as tapping the display or voice commands) and temporarily activates visual indicators showing connector locations. This periodic activation maintains dark display conditions for optimal viewing quality while periodically providing the necessary location detection information when users need to connect devices.

AI summary
A control unit (2) for depicting a position of a connector receptacle (4) located at an outer peripheral side of a display (3), a back of the display (3) or a recess compartment behind the display (3) is provided. The control unit (2) is configured to receive (S1) tap information that the display (3) has been tapped, and control (S2) the display to show a graphic (7) depicting the position of the connector receptacle (4) in response to the received tap information.
