Projection Screen Mount With Movable Locking Blockers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projection screen systems face challenges in ease of mounting and securing to environmental support structures like ceilings and walls, lacking efficient mechanisms to ensure stable attachment and detachment.
Innovation Solution
A support system for rollable materials, including a mount and housing with blockers that move between disengagement and engagement positions, allowing for easy attachment and secure locking to environmental support structures, ensuring the rollable material can be extended and retracted through a dispensing passage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a projection screen system is mounted to an environmental support structure, then the screen can be securely attached and detached, but the mounting process becomes complex and difficult
Solution Approach 1:
The blocker is designed as a movable component that can transition between engaged and disengaged positions. When moved to the engaged position, the blocker prevents detachment of the housing from the mount, providing secure attachment. When moved to the disengaged position, the blocker allows easy detachment. This dynamic mechanism resolves the contradiction by making the mounting system both secure during operation and easy to install or remove when needed.
2Stability of the object's composition
If the housing is permanently secured to the mount, then stability is improved, but the ability to detach and reposition becomes difficult
Solution Approach 1:
The blocker provides a dynamic locking mechanism that can be engaged to stabilize the housing-mount connection during normal operation, preventing accidental detachment. When the blocker is disengaged, the housing can be easily removed from the mount, enabling repositioning or maintenance. This dynamic system resolves the contradiction between stability and adaptability by allowing the user to switch between these two states as needed.
3Ease of manufacture
If simple mounting mechanisms are used, then ease of installation is improved, but the security and reliability of attachment deteriorates
Solution Approach 1:
The mounting system is segmented into distinct functional components: a mount attached to the support structure, a housing containing the projection screen, and a separate blocker component. The blocker acts as an independent security element that can be engaged or disengaged as needed. This segmentation allows the basic mounting structure to remain simple and easy to install, while the optional blocker provides enhanced security when required, resolving the contradiction between installation simplicity and attachment security.
