Foldable Flexible Display for Space-Limited Low-Voltage Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional low-voltage devices in electrical distribution boards and switching cabinets have limited display capabilities due to space constraints, preventing the display of complex information and requiring additional installation space.
Innovation Solution
A low-voltage device with a flexible, bendable, and/or foldable display unit that adapts to the housing contour, providing a larger display area without increasing the device's footprint, and includes features like touch sensitivity, thermal insulation, and a camera for monitoring the environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a simple display unit with small display area is used, then the device fits within limited switching cabinet space, but complex information cannot be displayed
Solution Approach 1:
The display unit is made dynamically configurable through foldable sections that can be extended or retracted based on information display needs. The display comprises multiple foldable sections that can be arranged in different configurations to provide either a compact profile for space-constrained installations or an expanded surface area for displaying complex information, thus resolving the contradiction between display area and device footprint.
Solution Approach 2:
The display unit employs a nested structure where multiple foldable sections can be collapsed into each other when not in use, allowing the display to occupy minimal space within the switching cabinet while still providing a large display area when extended. The sections are designed to nest together in a compact arrangement, enabling the display to transition between a small footprint state and an expanded information display state.
2Adaptability or versatility
If a flexible display unit is bent to fit housing contour, then the display adapts to curved surfaces, but manufacturing precision becomes more difficult
Solution Approach 1:
The display unit is divided into multiple discrete foldable sections rather than being a single continuous flexible surface. Each section can be manufactured with standard precision and then assembled together to form the complete display. The segments are connected through hinges or flexible joints that allow the display to conform to curved housing contours while maintaining manufacturing feasibility for each individual section.
Solution Approach 2:
The display employs thin, flexible display sections that can be bent and shaped to conform to curved housing surfaces. These thin-film display sections are designed with sufficient flexibility to adapt to various housing contours while maintaining their structural integrity and display functionality. The flexible nature of these thin sections allows them to be manufactured with standard tolerances and then shaped during assembly to match the specific housing geometry.
