Rotatable Control Unit Connector for Display Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices face challenges in compact configuration and easy insertion/removal of external connectors due to narrow insertion/removal spaces and poor workability, especially when the control unit is detached from the display unit.
Innovation Solution
The display device features a connection part that allows the control unit to be rotated and spaced apart from the display unit, enabling easy insertion/removal of external connectors by changing the insertion/removal direction to align with the display unit's back surface, and includes bend sections and abutment sections for secure engagement and detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the external connector is provided at the lower edge portion of the control unit for insertion/removal in the up-down direction, then the thickness of the housing is decreased and the display device becomes compact, but the insertion/removal space becomes narrow and workability is low
Solution Approach 1:
The control unit is designed to be rotatable relative to the display unit through a connection part. This dynamic configuration allows the control unit to be rotated so that the external connector faces an accessible direction during insertion/removal operations, improving workability while maintaining a compact housing thickness when connected.
Solution Approach 2:
The patent introduces rotational freedom in addition to the fixed up-down insertion direction. By allowing rotation around the connection axis, the system adds a dimensional degree of freedom that enables the external connector to be accessed from multiple directions, solving the narrow insertion space problem without increasing housing thickness.
2Volume of moving object
If the external connector is provided at the lower edge portion of the control unit, then the housing thickness is decreased, but it becomes difficult to see the insertion port when the control unit is attached to the back side of the display unit
Solution Approach 1:
The rotatable connection part allows the control unit to be dynamically repositioned to any angular orientation. This enables the external connector and its insertion port to be rotated into visible and accessible positions during operation, eliminating the visibility problem while maintaining compact housing dimensions.
3Device complexity
If cables connected to the external connector are fixed by a clamp member or bundled by being inserted through a duct, then the cables have almost no extra length, but the control unit removed from the display unit cannot be carried to the worktable
Solution Approach 1:
The patent employs a flexible cable structure that allows the control unit to be detached and moved independently. The cable maintains connection while accommodating movement, enabling the control unit to be carried to worktables for maintenance or connector operations without being constrained by rigid cable management systems.
4Volume of moving object
If the control unit is detachably connected to the back surface of the display unit, then the display device can be configured compactly, but the insertion/removal direction conflicts with the natural extension direction of the back surface
Solution Approach 1:
The connection part provides rotational freedom that allows the control unit to be oriented in different directions. This dynamic capability resolves the conflict between compact housing configuration and natural connector access direction, as the external connector can be rotated to face any convenient direction while the control unit remains compactly connected to the display unit's back surface.

AI summary
A display device according to the present disclosure comprises a display unit, a control unit that controls the display unit, and a connection part that connects the display unit and the control unit. The connection part can attach and detach the back surface side of the display unit and the control unit to and from each other. To the control unit, an external connector for connection with the outside thereof is connectable. In a state where the control unit is secured to the back surface side of the display unit, the mating/unmating direction of the external connector is a direction in which the back surface of the display unit extends, and the connection part rotatably connects the external connector in a state where the control unit is turnably disposed so as to move away from or toward the back surface side of the display unit and the external connector is disposed outside in a radial direction.
