Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices with transparent panels lack a mechanism for opening and closing the rear surface, limiting their functionality and user experience.
Innovation Solution
A display device with a transparent display panel, featuring a side frame, belt, bar, rotatable roller, and light-shielding film, which allows for the opening and closing of the rear surface through a mechanical drive mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a transparent display panel is used to maintain light transparency, then the display device allows users to see through the panel, but the rear surface cannot be opened or closed to access internal components
Solution Approach 1:
The rear surface cover is divided into a fixed portion and a movable portion that can be independently opened and closed. This segmentation allows the transparent display panel to maintain its light transparency while the segmented rear cover enables access to internal components when needed.
Solution Approach 2:
The rear surface cover is designed as a dynamic structure that can transition between closed and open states. The movable portion is coupled with a drive mechanism that enables controlled opening and closing, allowing the device to adapt between maintaining transparency and accessing internal components.
2Adaptability or versatility
If a mechanical drive mechanism is added to enable opening and closing of the rear surface, then rear surface accessibility is improved, but the device structure becomes more complex
Solution Approach 1:
A drive mechanism acts as an intermediary between the control system and the movable rear surface cover. This intermediary component translates control signals into mechanical motion, enabling the opening and closing function while maintaining a relatively simple overall structure.
Solution Approach 2:
The drive mechanism utilizes a belt with flexible properties to transmit motion. The belt's flexibility allows it to navigate around rollers and connect different components, achieving the desired movement function with a simple, lightweight structure that minimizes added complexity.
3Ease of operation
If a belt and roller mechanism is used to drive the rear surface cover, then the opening and closing function is achieved, but the device structure becomes more complex
Solution Approach 1:
The belt-driven roller mechanism is designed to be self-contained, where the belt loops around rollers and automatically transmits motion without requiring additional complex control mechanisms. The system serves itself by using the rotational motion of the roller to directly drive the opening and closing action.
