Existing lighting and staging devices for photography and display are complex, require high expertise, and struggle to achieve seamless, multi-hued, shadow-free illumination, especially when combining techniques like translucent up-lit surfaces and coved backgrounds, often necessitating multiple equipment and extensive setup.
Innovation Solution
A portable, easy-to-use article-display stage constructed from translucent Plexiglass with a built-in coved transition surface, utilizing external lighting instruments for flexible control of luminance, color, focus, and angle, allowing for seamless illumination with minimal equipment and setup time, and the ability to create multi-hued surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If multiple lighting instruments and complex staging devices are used to achieve seamless illumination and infinity background effects, then the quality of illumination improves, but the device complexity and expertise required increase significantly
Solution Approach 1:
The patent combines the background surface and staging surface into a single continuous translucent surface that curves seamlessly from vertical to horizontal, eliminating the need for separate background panels and staging platforms. This unified structure reduces device complexity while maintaining seamless illumination quality.
Solution Approach 2:
The translucent staging surface serves multiple functions simultaneously: it acts as the background surface, the staging platform for the subject, and the diffusion medium for lighting. This multi-functionality eliminates the need for separate background panels and complex lighting rigs, reducing both device complexity and expertise requirements.
2Object-affected harmful factors
If multiple lighting instruments are used to illuminate from front, sides, and above, then shadow coverage improves, but the quantity of equipment and setup time increase
Solution Approach 1:
The translucent surfaces themselves perform the lighting function by diffusing light from a single source placed behind the structure. The surfaces automatically scatter and redirect light to eliminate shadows, eliminating the need for multiple external lighting instruments and reducing equipment quantity.
Solution Approach 2:
The translucent surfaces act as intermediaries between the single light source and the subject, diffusing and redirecting light to achieve comprehensive shadow coverage. This intermediary function replaces the need for multiple direct lighting instruments positioned around the subject.
3Device complexity
If fixed internal lighting sources are used in the Durand device, then the structure is simpler, but the adaptability for varying luminance, color, and focus is lost
Solution Approach 1:
The patent replaces fixed internal lighting with a dynamic external lighting system where a single adjustable instrument can vary luminance, color, and focus in real-time. The translucent surfaces maintain their simple structure while the external lighting provides dynamic adaptability for different photographic requirements.
Solution Approach 2:
The invention allows continuous adjustment of lighting parameters (luminance, color temperature, focus) using a single external instrument positioned behind the translucent structure. This enables versatile lighting control without modifying the simple translucent structure itself, achieving both structural simplicity and lighting adaptability.

AI summary
The display stage includes a top and bottom compartments. The top compartment is defined by a translucent horizontal wall having a front end, and top and bottom surfaces extending rearwardly from the front end to a translucent backwall having front and rear surfaces. The bottom compartment is defined by an angular wall extending downwardly from the horizontal-wall front end and has a reflective surface facing the bottom surface of the horizontal wall. A light source behind the compartments provides illumination of an article disposed on the horizontal wall, by directing light at both at the rear surface of the backwall and the reflective surface of the angular wall.
