Sliding UST Projector Credenza for Flush Wall Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ultra-short throw (UST) projector cabinets are not universal, require separate furniture for different projector models, occupy excessive space due to fixed positioning, lack cooling systems, and expose projectors to dust and particles, leading to reduced equipment lifespan and aesthetic issues.
Innovation Solution
A universal sliding UST projector compartment with a climate-controlled cooling system, magnetic actuator for safety, and a motorized or manual sliding mechanism that allows flush mounting against walls, incorporating a low-profile rising screen and integrated speakers, compatible with all UST projectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed credenza is used to house the UST projector, then the projector is securely supported, but the cabinet occupies excessive space and cannot be positioned close to the wall
Solution Approach 1:
The patent applies a sliding mechanism that transforms the static cabinet structure into a dynamic system. The projector compartment can slide along the cabinet body between retracted and extended positions, allowing the cabinet to adapt its effective width based on projection distance requirements while maintaining a compact footprint when not in use.
Solution Approach 2:
The cabinet is divided into functional segments: a fixed cabinet body, a movable projector compartment, and a separate screen assembly. This segmentation allows each component to be optimized independently and enables the projector compartment to be positioned at different distances from the wall without requiring the entire cabinet to be reconfigured.
2Adaptability or versatility
If custom-made cabinets are manufactured for specific projectors, then the fit and support are optimized, but the cabinets cannot be adapted when projector models are upgraded or replaced
Solution Approach 1:
The cabinet employs universal mounting brackets and standardized opening dimensions that can accommodate multiple projector models. The sliding compartment design with adjustable positioning allows the same cabinet structure to support different projector sizes and types, eliminating the need for custom manufacturing for each projector model.
3Manufacturing precision
If the cabinet is pulled away from the wall for larger projection images, then the throw ratio requirement is met, but the working and sound space in the entertainment room is impinged
Solution Approach 1:
The sliding mechanism enables the projector compartment to dynamically adjust its position along the cabinet body. When close to the wall, the compartment retracts, minimizing the cabinet's effective width and preserving entertainment room space. When positioned farther from the wall, the compartment extends to provide the necessary throw distance for large projection images.
4Device complexity
If no cooling system is included in the cabinet, then the cabinet structure remains simple, but the projector components are exposed to dust and particles that can clog filters and heat sinks
Solution Approach 1:
The patent integrates the cooling system directly into the cabinet structure, merging the ventilation function with the housing. The cabinet incorporates filtered air intake openings and heat sink mounting structures as built-in features, providing thermal management and dust protection without requiring separate external cooling equipment.
5Ease of operation
If a sliding mechanism is added to the cabinet, then the projector can be positioned close to the wall, but the device complexity increases
Solution Approach 1:
The sliding mechanism transforms the static cabinet structure into a dynamic system. The projector compartment can slide along the cabinet body between retracted and extended positions, allowing the cabinet to adapt its effective width based on projection distance requirements while maintaining a compact footprint when not in use.

AI summary
Universally adjusting Ultra Short Throw (UST) projector credenza having a sliding UST compartment allowing for the cabinet to lie flush or near flush with a forward wall. The UST compartment expands out to a predetermined position to accommodate projecting images onto 100+ inch screens above. Each UST compartment comes with a cross-drilled and ventilated floating shelf that can be adjusted in three dimensions withing the compartment to allow adjustments. Ventilation holes in the shelf aerate the projector without obstructing ventilation. The UST compartment may have a low iron pane of glass over the projector to make it more discrete and hidden, but does not obstruct the image or color of the projected image passing through it in any way.
