Rotatable Operation Unit for Camera Display Operability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image pickup apparatuses, such as digital cameras, face challenges in improving the operability of their operation units when the image display unit is adjusted to an angle for better visibility, as the operation unit is not easily rotatable relative to the camera main unit, affecting user interaction.
Innovation Solution
An image display device with a detachable mounting unit, a rotatable image display unit coupled to an operation unit via a hinge mechanism, and a rotary mechanism allowing the operation unit to rotate relative to the mounting unit, enabling independent adjustment of both units for improved usability.

Engineering Contradiction Analysis
1Illumination intensity
If the image display unit is adjusted to an angle for better visibility, then the visibility of displayed images is improved, but the operability of the operation unit is lowered
Solution Approach 1:
The display device is divided into functionally independent modules: the image display unit and the operation unit. Each module can be adjusted independently - the image display unit can be rotated about the first rotation axis to improve visibility, while the operation unit can be rotated about the second rotation axis to maintain optimal operability. This segmentation allows simultaneous optimization of both visibility and operability without mutual interference.
Solution Approach 2:
The patent introduces dual rotation mechanisms that enable dynamic adjustment of both the image display unit and operation unit. The first rotation mechanism allows the image display unit to rotate about the first rotation axis, while the second rotation mechanism allows the operation unit to rotate about the second rotation axis. This dynamic capability ensures that users can continuously optimize both visibility and operability according to their needs.
2Device complexity
If the operation unit is formed integrally with the camera main unit, then the device complexity is reduced, but the adaptability of the operation unit is limited
Solution Approach 1:
The operation unit is separated from the camera main unit and integrated with the display device through the hinge mechanism. This segmentation allows the operation unit to be rotated independently about the second rotation axis, providing adaptability while maintaining a relatively simple overall structure. The modular design enables the operation unit to adapt to different operational scenarios without significantly increasing device complexity.
Solution Approach 2:
The operation unit is designed with multi-functionality, serving both as a control interface for the camera and as a rotatable component that can be positioned optimally for user interaction. The hinge mechanism and second rotation mechanism enable the operation unit to perform multiple functions: controlling the camera, displaying information, and being positioned at various angles for different user preferences and shooting scenarios.
3Illumination intensity
If the display device is configured to be rotatable relative to the camera main unit, then the visibility of displayed images is improved, but the operability of the operation unit is affected when the display is adjusted to an optimal viewing angle
Solution Approach 1:
The display device is segmented into independently controllable rotational components. The image display unit can be rotated about the first rotation axis to optimize viewing angle, while the operation unit can be rotated about the second rotation axis to maintain optimal operability. This segmentation resolves the conflict by allowing each component to be optimized independently.
Solution Approach 2:
The hinge mechanism acts as an intermediary between the image display unit and the operation unit, enabling independent rotation of each component. This intermediary mechanism allows the image display unit to rotate for better visibility while the operation unit maintains its optimal position for operation, effectively mediating between the two conflicting requirements.

AI summary
An image display device that improves the operability of its operation unit when operated by a photographer/user in a state that an image display unit of the device has been adjusted to assume an angle where the photographer/user can easily view a displayed image. The image display device is coupled through its mounting unit to an image pickup apparatus main unit and causes the image display unit to display an image captured by the apparatus main unit. The image display device has an operation unit configured to be operated to control the apparatus main unit and the image display unit. The image display unit is coupled through a hinge mechanism to the operation unit for rotation relative thereto and the operation unit is coupled through a rotary mechanism to the mounting unit for rotation relative thereto about a rotation axis perpendicular to an operation face of the operation unit.
