Robot Display System with Dust-Preventing Conical Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display systems for robots suffer from dust accumulation due to the need for a heat abstractor, which affects the graphic effects and user experience by deteriorating image quality over time.
Innovation Solution
A display system for robots featuring a housing with a screen and a projection unit, where a funnel-shaped cover prevents dust from entering the space between the screen and the projection unit, utilizing a digital light processing equipment to project clear images, and the screen is made from light-transmitting materials like polymethyl methacrylate or glass.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a heat abstractor is used to cool the projecting apparatus, then the projecting apparatus can be cooled during operation, but dust accumulates and affects graphic effects
Solution Approach 1:
The housing is divided into multiple sections: a main body, a top section with upward projection, and a base. The screen is embedded in the housing surface, creating distinct functional zones that separate the projection path from dust-prone areas.
Solution Approach 2:
A cover is introduced as an intermediary component between the projection unit and the screen. This cover prevents dust from entering the projection space while allowing light to pass through, mediating between the cooling requirement and dust prevention needs.
2Area of stationary object
If the screen is made larger to provide a bigger display, then the visual area is increased, but the structural complexity of the housing increases
Solution Approach 1:
The screen is embedded directly into the housing surface, merging the display function with the structural housing. The housing itself becomes part of the display system, eliminating the need for separate mounting structures and reducing overall complexity.
Solution Approach 2:
The housing serves multiple functions: it provides structural support, defines the robot's外形, and serves as the mounting surface for the screen. This multi-functionality reduces the need for additional components and simplifies the overall structure.

AI summary
The invention discloses a display system of a robot. The robot's housing comprises: a main body having an annular curved surface; a top portion, located above and integral with the main body, and having a curved surface protruding upwards; and a base located below and connected to the main body. A display system located inside the housing comprises a receiving unit configured to receive a video signal; a screen embedded at the housing's surface; a projection unit, located opposite to the screen, and configured to project an image onto a back side of the screen; and a cover disposed between the projection unit and the screen and having a conical shape, wherein a narrow end of the cover is connected to the projection unit, a wide end of the cover is connected to the screen, and the wide end's exterior shape matches the screen's peripheral size.
