Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing illumination systems for projecting shapes onto spaces or objects are complex and limited, requiring users to adjust optical axes manually and monitor camera images, making it difficult to intuitively set illumination parameters and visualize three-dimensional effects.
Innovation Solution
An optical projection apparatus with a simple configuration that allows users to set light specifications, shapes, positions, and sizes directly with a manipulation unit, generating optical data for projecting shapes onto spaces or objects without the need for a driving unit to adjust optical axes, enabling intuitive parameter setting and real-time visualization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a driving unit is used to change the irradiation direction by adjusting the optical axis of the illumination device, then the irradiation direction can be changed, but the system becomes complicated and scaled up
Solution Approach 1:
The patent removes the driving unit and optical axis adjustment mechanism from the system. Instead of physically changing the illumination device orientation, the system extracts only the necessary function of direction control by using a fixed illumination device combined with a display device that shows projection positions, eliminating unnecessary mechanical components.
Solution Approach 2:
The patent replaces the mechanical optical axis adjustment system with an information-based control system. The display device shows the projection position and shape on the screen, allowing users to set illumination parameters visually without mechanical movement, substituting mechanical adjustment with visual information processing.
2Ease of operation
If a camera and display device are used to monitor captured images for setting projection positions, then position setting is enabled, but the apparatus becomes complicated and scaled up
Solution Approach 1:
The display device serves multiple functions: it displays the projection position, shows the shape to be projected, and provides visual feedback for parameter setting. By making the display device multi-functional, the patent reduces the need for separate camera and monitoring systems, simplifying the overall apparatus while maintaining position setting capability.
3Ease of operation
If users set projection parameters while monitoring camera-captured images on a display device, then parameter setting is possible, but users cannot check the actual result instantly and accurately with their naked eye
Solution Approach 1:
The display device provides real-time visual feedback showing the projection position and shape overlaid on the captured image. This feedback mechanism allows users to see the expected projection result before actual illumination, enabling accurate parameter setting with visual confirmation without losing the ability to check results with the naked eye.

AI summary
An optical projection apparatus includes a light specification setting unit for setting a specification of a light, a shape setting unit for setting a shape made by the light, a position setting unit for setting a position of the shape, a size setting unit for setting a size of the shape, an optical data generation unit for generating optical data based on the specification, the shape, the position, and the size. The optical projection apparatus further includes a light drawing unit for generating light drawing data by performing a drawing process with the optical data, an optical projection unit for projecting the shape at the position with the light drawing data, and a manipulation unit for allowing a user to set one or more parameters indicating the specification, the shape, the position, and the size.
