Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If screens are manufactured from solid panels using molds, then structural stability is improved, but manufacturing complexity and cost increase significantly for variable dimensions
Solution Approach 1:
The patent applies the dynamics principle by using an inflatable structure that can be dynamically adjusted to different dimensions and configurations. The structure transitions from a deflated state to an inflated operational state, allowing variable geometry without requiring multiple fixed molds. This dynamic approach enables the same structure to adapt to different simulation requirements while maintaining structural stability through controlled inflation pressure.
Solution Approach 2:
The invention utilizes parameter changes by varying the inflation pressure and volume of the inflatable structure to achieve different screen dimensions and curvatures. By changing the physical parameters of the inflatable material (expansion ratio, pressure), the system can produce screens of variable sizes without requiring different manufacturing molds, thus reducing complexity while maintaining structural integrity.
2Manufacturing precision
If screens are manufactured from solid panels with predefined dimensions, then manufacturing precision is improved, but adaptability to different fields of view deteriorates
Solution Approach 1:
The inflatable structure provides dimensional precision through controlled inflation while maintaining adaptability. The structure can be inflated to specific dimensions and shapes as needed, allowing the same component to achieve multiple precise configurations rather than requiring multiple pre-manufactured panels with fixed dimensions.
Solution Approach 2:
By changing the inflation parameters (pressure, volume, distribution), the system can achieve different screen dimensions and curvatures with controlled precision. The inflatable material responds predictably to pressure changes, enabling reproducible dimensional accuracy across different configurations without requiring different manufacturing tools.
3Productivity
If molds are used for screen production, then manufacturing efficiency is improved for fixed dimensions, but productivity for variable dimensions deteriorates
Solution Approach 1:
The inflatable structure serves multiple functions: it can be inflated to different sizes, shapes, and configurations as needed. A single universal inflatable component replaces the need for multiple specialized molds, allowing the system to efficiently produce screens of variable dimensions without requiring tooling changes or reconfiguration.
Solution Approach 2:
The system achieves manufacturing efficiency for variable dimensions by changing the inflation parameters rather than changing physical molds. This allows rapid reconfiguration between different screen sizes and shapes, maintaining high productivity while providing full dimensional flexibility.
4Ease of manufacture
If captive-air inflatable structures are used, then ease of manufacture is improved, but structural stability may deteriorate
Solution Approach 1:
The patent employs pneumatic principles by using captive air pressure to maintain the structural form and stability of the inflatable screen. The trapped air provides continuous internal pressure that supports the structure against external forces, ensuring stability during operation. The system includes pressure control mechanisms to maintain optimal stability while keeping the structure inflated.
Solution Approach 2:
The inflatable structure uses flexible materials that can maintain structural integrity when pressurized. The thin film or shell material is designed to withstand the internal air pressure while providing the necessary structural support, combining ease of manufacture with operational stability.

AI summary
An assembly for video display, includes a captive-air inflatable structure in a curved shape or a portion of a truncated sphere; a display medium; and a holding system between the inflatable structure and the display medium; the assembly wherein the holding system comprises hooks distributed over the surface of the concave part of the inflatable structure and complementary hooks distributed over the convex surface of the display medium; and in that all or some of the hooks are connected to complementary hooks positioned facing them, so that, when the inflatable structure is inflated, the hooks of the inflatable structure connected to complementary hooks of the display medium are stretched and make it possible to shape the display medium.
