Sliding UST Projector Credenza for Flush Wall Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ultra-short throw projector systems require fixed credenzas that are not universal, leading to space inefficiencies and aesthetic issues, as they must be replaced or upgraded when projector technology advances, and lack cooling and dust protection, causing equipment failure over time.
Innovation Solution
A universal sliding UST projector compartment with a climate-controlled cooling system and magnetic actuator drive for safety, allowing for motorized or manual adjustment, and integration with a low-profile rising screen to create a compact all-in-one AV/home theater system that accommodates various projector sizes and technologies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a fixed credenza is used to house the UST projector, then the projector is supported and housed, but the cabinet must be pulled away from the wall substantially for larger projection images, eating up space in the entertainment venue
Solution Approach 1:
The patent applies a sliding mechanism that allows the credenza to dynamically adjust its position. The cabinet can slide along a track system to extend outward when large projection images are needed, and retract close to the wall when not in use. This dynamic positioning resolves the contradiction by providing both compact storage space and adequate projection distance on demand.
Solution Approach 2:
The credenza is divided into a stationary base portion and a movable sliding portion. The sliding portion containing the projector can be independently extended or retracted relative to the stationary base. This segmentation allows the system to maintain a compact footprint while providing the necessary extension for large-scale projections.
2Ease of manufacture
If current UST cabinets are used, then the projector is housed, but the components are exposed to outside particles that can get clogged into filters and heat sinks causing equipment to work harder and harder over its life span
Solution Approach 1:
The patent incorporates sealed enclosures with filtered air intake systems. Thin film filters are integrated into the cabinet structure to allow airflow while blocking dust and particles. This protective barrier maintains reliability by preventing particle ingress while preserving the simplicity of the overall cabinet design.
Solution Approach 2:
The patent creates a protected internal environment within the credenza using sealed compartments and positive pressure ventilation systems. This inert environment prevents dust and particles from reaching sensitive components, thereby extending equipment lifespan without significantly complicating the cabinet design.
3Device complexity
If current UST cabinets are used, then the projector is housed, but there is no cooling system, causing equipment to work harder over time till it fails
Solution Approach 1:
The patent implements self-service cooling through passive thermal management features integrated into the cabinet structure. Heat sinks are designed to dissipate heat naturally through convection, and airflow channels are configured to automatically draw cool air in and exhaust hot air out without requiring active cooling components. This maintains operational stability while minimizing system complexity.
Solution Approach 2:
The patent introduces heat sinks and thermal interface materials as intermediaries between the projector and the surrounding air. These components facilitate efficient heat transfer from the projector to the ambient environment, providing reliable cooling without adding complex active cooling systems to the cabinet.
4Manufacturing precision
If custom made or premanufactured cabinets for specific projectors are used, then the projector fits precisely, but when the UST is replaced or upgraded, the supporting furniture cabinets are not adaptable and must also be replaced
Solution Approach 1:
The patent designs the credenza with universal mounting features and adjustable support structures that can accommodate multiple projector models and sizes. Standardized mounting interfaces and reconfigurable interior compartments allow the same cabinet to adapt to different projector technologies, providing both precise fit and upgradeability without requiring cabinet replacement.

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.
