Universal Projector Mount with Shiftable Coupling Arms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projector mounts are not easily adaptable to multiple projector makes, requiring multiple mount models and complicating serviceability, as they often interfere with serviceable parts like filters and bulbs, necessitating time-consuming re-aiming after maintenance.
Innovation Solution
A universal projector interface with elongate arm assemblies that are selectively rotatable and translatable, allowing secure engagement and disengagement with projector attachment members, enabling precise aiming and easy serviceability without affecting existing adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a universal projector interface with selectively shiftable coupling portions is used, then ease of serviceability and adaptability to multiple projector models is improved, but device complexity increases due to the shiftable coupling mechanism
Solution Approach 1:
The coupling portion is designed to universally engage with different projector attachment members through a standardized interface geometry. The elongate arm assembly with shiftable coupling can accommodate multiple projector models by maintaining consistent engagement features while allowing positional adjustment, eliminating the need for multiple specialized mount models.
Solution Approach 2:
The coupling portion incorporates selective shiftability between engaged and disengaged positions, enabling dynamic reconfiguration. This allows the mounting device to transition from a fixed-state design to a dynamically adjustable system where the coupling can be easily shifted to engage or disengage from projector attachment members during installation and service operations.
2Reliability
If the coupling portion is securely engaged to prevent translation, then reliability of projector positioning is improved, but ease of operation for attachment and detachment deteriorates
Solution Approach 1:
The coupling portion is designed with selective shiftability between two distinct states: an engaged position where it securely prevents translation for reliable positioning, and a disengaged position where it allows easy attachment and detachment. This dynamic design resolves the contradiction by allowing the system to switch between high reliability and high ease-of-operation modes as needed.
Solution Approach 2:
The mounting device separates the coupling function into distinct positional states rather than requiring continuous adjustment mechanisms. The coupling portion can be selectively positioned in discrete engaged or disengaged states, simplifying the operation while maintaining secure engagement when needed.
3Manufacturing precision
If multiple separate fasteners are used for adjustment, then manufacturing precision and secure mounting are improved, but ease of operation and productivity deteriorate due to the number of fasteners to be loosened and tightened
Solution Approach 1:
The mounting device merges multiple separate fastening operations into a single integrated coupling mechanism. Instead of requiring multiple independent fasteners to be individually adjusted, the selective shiftable coupling consolidates the attachment and positioning functions into one unified operation that can be engaged or disengaged as a single unit, significantly improving productivity while maintaining precision.

AI summary
A universal projector interface including a mount interface portion with a plurality of elongate arm assemblies coupled thereto. Each arm assembly is selectively rotatable and translatable relative to the mount interface, and includes a coupling portion. The coupling portion of each arm assembly is selectively shiftable between a first position in which the coupling portion is securely engaged with a projector attachment member on the projector and a second position in which the coupling portion is freely disengageable from the projector attachment member.
