Flexible Display Device with Pivotable Lever Mechanism for Motor Vehicle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle display devices, such as touchscreens, often require large receiving areas and can distract drivers due to complex menu structures, and their mechanical retractable designs are costly and ergonomically inefficient, requiring whole-hand movement for operation.
Innovation Solution
A flexible display device with a pivotable lever mechanism that bends from a stowed to a use position, maintaining a constant hand-to-display distance, allowing for ergonomic operation and adjustable curvature for different users, and featuring a multi-layer structure with an antistatic coating to prevent layer attraction and visual distortion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a mechanical retractable design is used to move the display from stowed to use position, then the display can be hidden when not in use, but the construction becomes expensive and requires robust mechanical components
Solution Approach 1:
The patent replaces the mechanical retractable system with an electronically controllable flexible display that can be bent or folded. This substitution eliminates complex mechanical components like drive gear wheels and robust housing structures, thereby reducing manufacturing costs and device complexity while maintaining the ability to hide the display when not in use.
Solution Approach 2:
The patent employs a flexible display device that can be bent or folded into a compact form. This flexible membrane approach allows the display to be stored in a space-efficient manner without requiring expensive mechanical retraction mechanisms, directly addressing the contradiction between manufacturing cost and device complexity.
2Adaptability or versatility
If a large touchscreen is used to accommodate many control elements, then the user interface capacity is improved, but the receiving area inside the vehicle increases
Solution Approach 1:
The patent uses a flexible display that can be folded or bent into a compact nested form when not in use. This nesting principle allows a large-capacity display to be housed in a small receiving area, effectively resolving the contradiction between user interface capacity and space requirements.
Solution Approach 2:
The patent transitions the display from a two-dimensional flat surface to a three-dimensional folded or bent structure. This dimensional change enables the display to occupy minimal space in the receiving area while maintaining large surface area for control elements when deployed, effectively addressing the space-capacity contradiction.
