Power Supply Interruption for Rotating Camera Imaging Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display terminals with rotatable imaging units face issues with battery energy exhaustion and temperature rise when the camera direction is changed, leading to incorrect image display and potential damage to electronic components.
Innovation Solution
Incorporating a detection unit that interrupts the power supply to the imaging unit when the camera direction changes, temporarily halting electric power to conserve battery energy and reduce heat generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the camera is rotated during imaging to change the direction of imaging, then the imaging direction can be changed to capture different scenes, but the image displayed on the display may be disordered temporarily and battery energy is exhausted quickly
Solution Approach 1:
The power supply to the imaging unit is periodically interrupted during camera rotation. The control unit stops power supply when rotation is detected, then resumes it after rotation completes, creating a periodic on-off pattern that reduces energy consumption during the non-imaging rotation phase while maintaining imaging capability when needed.
2Adaptability or versatility
If the camera is rotated during imaging to change the direction of imaging, then the imaging direction can be changed, but the temperature inside the camera rises higher
Solution Approach 1:
By periodically interrupting power supply during camera rotation, the imaging unit is not energized during rotation movements. This reduces continuous heat generation from the image sensor and processing circuits, allowing heat to dissipate during rotation intervals and preventing excessive temperature buildup while maintaining operational temperature when imaging.
3Duration of action of moving object
If the power supply is continuously performed to the imaging unit during direction change, then the image can be continuously generated, but the exhaustion of the battery energy is fast and electronic parts may be damaged
Solution Approach 1:
The system uses periodic power supply interruption synchronized with camera rotation detection. Power is cut during rotation when no imaging occurs, reducing energy consumption and heat generation that could damage electronic parts. Power is restored immediately after rotation completes, ensuring continuous imaging operation when the camera is in a stable imaging position.

AI summary
A display terminal, in which a supply of electric power from a battery can also be performed, includes an imaging unit that performs imaging to generate an image; a display unit that displays the image generated by the imaging unit; a detection unit that detects whether a direction of the imaging unit while imaging to generate the image to be generated by the imaging unit is being changed; and a power supply interruption unit that interrupts the supply of the electric power from the battery to the imaging unit when the detection unit detects that the direction of imaging to generate the image to be generated by the imaging unit is being changed.
