Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices suffer from instability when the angle of the display screen's variable area is changed, leading to warping of the invariant area.
Innovation Solution
A display device with a clipping structure that includes a controlling module, transmission module, and telescopic module, where the telescopic module is used to clip and fix the invariant area of the display screen, preventing warping by switching between extending and compressing states, and the transmission units are designed to transmit force for stable fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display angle of the variable area is changed, then the adaptability of the display device is improved, but the stability of the invariant area deteriorates causing warping
Solution Approach 1:
The display screen is divided into a variable area and an invariant area, allowing independent control of each region. The variable area can change display angles while the invariant area maintains stability through separate support structures and clipping mechanisms.
Solution Approach 2:
Different regions of the display screen are given different functional properties. The variable area is designed for angle adjustment while the invariant area is reinforced with clipping structures to maintain stability, creating local quality differences that resolve the contradiction.
2Stability of the object's composition
If the clipping structure is added to fix the invariant area, then the stability of the invariant area is improved, but the device complexity increases
Solution Approach 1:
The clipping structure incorporates telescopic modules that can dynamically adjust between extending and compressing states, allowing the structure to adapt to different display configurations while maintaining stability when needed.
Solution Approach 2:
Transmission modules serve as intermediaries between the controlling module and telescopic modules, simplifying the control architecture by decoupling the control system from the mechanical actuation system.
3Ease of operation
If the telescopic module switches between extending and compressing states, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The telescopic module utilizes elastic connecting units that automatically return to their original state after deformation, providing self-service functionality that simplifies operation while reducing the need for complex control mechanisms.
Solution Approach 2:
The design replaces complex electronic control systems with mechanical elastic elements that automatically manage the telescopic module's state transitions, substituting mechanical self-regulation for electronic control complexity.
