Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices, particularly those used in inflight entertainment, face challenges in absorbing or mitigating external impacts, leading to potential damage and breakage.
Innovation Solution
The display device incorporates a frame with a plate and back cover configuration, where the plate includes a damper that can stretch or compress in the front-and-rear direction, and an antenna assembly with an optical system to provide light to icons on the display panel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a rigid structure is used to achieve device rigidity, then structural stability is improved, but impact resistance deteriorates
Solution Approach 1:
A damper is disposed between the plate and back cover to provide beforehand cushioning against external impacts. The damper is configured to be stretched or compressed in a front-and-rear direction, absorbing impact energy before it can reach the display panel, thus protecting the rigid structure from impact damage.
Solution Approach 2:
The display device employs a composite structure combining rigid components (frame, plate, back cover) with a compliant damping element. This composite design allows the structure to maintain rigidity for structural stability while the damper provides impact absorption, resolving the contradiction between rigidity and impact resistance.
2Stability of the object's composition
If the display panel is firmly fixed to the frame, then structural stability is improved, but ease of repair deteriorates
Solution Approach 1:
The coupling part is designed as a detachable component that separates the display panel from the frame assembly. This segmentation allows the display panel to be easily removed and replaced without damaging other components, while the coupling part itself provides sufficient structural stability when assembled.
3Adaptability or versatility
If separate assemblies are used for antenna and optical components, then functional versatility is improved, but device complexity deteriorates
Solution Approach 1:
The antenna assembly and optical assembly are merged into a single integrated unit. The optical assembly is coupled to the carrier assembly of the antenna, allowing both functions to be implemented together. This merging reduces the number of separate components and simplifies the overall device structure while maintaining functional versatility.
