Solution Overview
Problem
Conventional portable display devices lack a compact and efficient solution for deployment, often requiring cumbersome setup and inadequate for varying projector alignments, while also being prone to vibrations and light interference.
Innovation Solution
A collapsible display device with a Spontaneous Pop-Up (SPUD) mechanism, featuring a compact portable form that deploys into a large screen with adjustable arms, improved screen materials, and a shroud to absorb ambient light, along with vibration-dampening features and optical enhancements for improved image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If a portable display device is made collapsible to improve portability, then the device can be stored in a compact form, but the deployment mechanism becomes more complex and may not provide stable screen alignment
Solution Approach 1:
The display device is divided into collapsible arms that can be segmented into multiple sections, allowing the screen to be folded into a compact form for portability while maintaining structural integrity when deployed. Each arm segment can be independently positioned to achieve stable screen alignment.
Solution Approach 2:
The collapsible arms are pre-configured with alignment guides and positioning mechanisms that automatically align the screen to the projector before deployment is complete. This preliminary alignment preparation ensures stable screen positioning without requiring complex active adjustment mechanisms during deployment.
2Illumination intensity
If conventional screen materials are used to improve visibility, then the screen provides basic display functionality, but the screen is susceptible to vibrations and light interference
Solution Approach 1:
The screen uses a composite material structure combining a flexible substrate with a vibration-dampening layer and a light-filtering coating. The vibration-dampening layer absorbs mechanical vibrations, while the light-filtering coating blocks ambient light interference, maintaining visibility while protecting against harmful factors.
Solution Approach 2:
The screen material converts the harmful effect of vibrations into a beneficial damping effect by incorporating vibration-absorbing materials that dissipate mechanical energy. Similarly, ambient light interference is converted into a benefit by using light-filtering properties to enhance contrast and visibility.
3Adaptability or versatility
If the display device is designed with adjustable arms for varying projector alignments, then adaptability to different positions is improved, but the structural stability and screen flatness become more difficult to maintain
Solution Approach 1:
The arms are designed with dynamic adjustment capabilities, allowing them to be positioned at various angles to accommodate different projector alignments. The arms incorporate locking mechanisms that maintain the adjusted position, providing both adaptability and structural stability simultaneously.
Solution Approach 2:
The screen material and support structure have different local properties: the screen surface maintains flatness through localized tensioning, while the arms provide adjustable positioning. Each component is optimized for its specific function, with the screen focusing on flatness and the arms focusing on adaptability.
4Object-affected harmful factors
If a shroud is added to absorb ambient light and improve image quality, then light interference is reduced, but the device structure becomes more complex and bulkier
Solution Approach 1:
The shroud is implemented as a flexible, thin-film structure that can be collapsed into a compact form when not in use. This flexible shell design provides effective ambient light blocking while minimizing structural complexity and bulk, allowing the shroud to be integrated with the collapsible arms.
