Solution Overview
Problem
Existing display devices face issues with noise and vibration during the operation of doors, and there is a need for a mechanism to power the opening and closing of these doors efficiently.
Innovation Solution
A display device incorporating a flexible display panel with a roller mechanism, a housing, and a door assembly powered by a motor through a shaft gear system, which includes first and second shafts and gears to facilitate smooth operation of the door.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a motor is directly connected to the door to provide power for opening and closing, then the door can be driven, but noise and vibration are generated during operation
Solution Approach 1:
A shaft gear mechanism is introduced as an intermediary between the motor and the door. The motor drives the first shaft gear, which transmits power through the first shaft and joint to the second shaft gear, ultimately driving the door. This intermediary transmission system reduces direct motor-door connection, thereby minimizing noise and vibration while maintaining reliable door operation.
2Object-generated harmful factors
If a simple direct drive mechanism is used for the door, then the structure is simple, but it cannot effectively reduce noise and vibration
Solution Approach 1:
The shaft gear mechanism serves as a controlled intermediary that balances complexity and noise reduction. The first shaft gear connected to the motor, coupled with the first shaft and joint, and connected to the second shaft gear that drives the door, creates a structured transmission path. This organized complexity effectively reduces noise and vibration compared to direct drive, while maintaining reasonable structural complexity.
3Adaptability or versatility
If a flexible display panel is rolled on a roller, then the display device can be made flexible and space-saving, but the roller mechanism adds complexity to the housing structure
Solution Approach 1:
The flexible display panel is nested within the housing structure, rolled around the roller that is rotatably mounted inside the housing's internal accommodation space. The roller is positioned adjacent to the housing opening, allowing the display panel to be stored in a compact form while maintaining flexibility. This nesting approach enables space-saving flexibility while integrating the roller mechanism efficiently within the existing housing.
