Projector Cart Control Layout for Standing Projection Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Position adjustment is difficult when projection mapping is performed using multiple projectors.
Innovation Solution
A projector cart with a housing, wheels, and a gripper that includes an operation panel for changing the electrical state of the projector, allowing for easy movement and position adjustment in a standing posture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the projector is placed in a cart for movement, then the ease of moving the projector is improved, but the ease of operation deteriorates because the operation panel becomes difficult to access
Solution Approach 1:
The operation panel is moved from the front surface to the top surface of the cart, changing its spatial dimension. This allows the operator to access the panel from above while the cart is being moved or positioned, resolving the contradiction between ease of moving and ease of operation.
2Ease of operation
If the operation panel is located on the front surface of the cart, then the ease of operation is improved, but the risk of erroneous operations increases during movement
Solution Approach 1:
A cover member is introduced as an intermediary between the operator and the operation panel. The cover member can be opened to access the panel for operation and closed during movement to prevent accidental operations, thus reducing the risk of erroneous operations while maintaining ease of operation when needed.
3Adaptability or versatility
If the projector is moved frequently for projection mapping, then the adaptability is improved, but the time required for positioning deteriorates
Solution Approach 1:
The cart is equipped with wheels that enable self-propelled movement, and the operation panel on the top surface allows for quick power-on and positioning adjustments. This self-service capability reduces the time required for positioning during frequent moves while maintaining adaptability.

AI summary
A projection system includes a projector and a projector cart, in which the projector includes an enclosure, a light source in the enclosure, a light modulator in the enclosure and configured to modulate light emitted from the light source, a projection lens unit configured to emit the light modulated by the light modulator to an outside of the enclosure, and a power supply substrate in the enclosure and configured to supply power to the light source, and in a state in which the projector is in use, the projector cart includes a housing which is configured to house the projector and is configured to emit the light emitted from the projection lens unit to an outside of the projector cart, wheels placed vertically below the housing, and a first operator is located vertically above the housing and is configured to change an electrical state of the power supply substrate.
