Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with flexible displays face challenges in expanding display area without compromising portability, particularly in slidable types where the sliding structure's movement relative to a fixed structure affects the exposed display area.
Innovation Solution
Incorporating a driving unit, such as a spring module, between the sliding and fixed structures to enable the electronic device to switch between expanded and reduced states, with the driving unit disposed on the rear surface of the sliding structure, allowing users to operate it by sliding the display or structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a sliding structure is used to expand the display area, then the display area is increased, but the device complexity increases due to the need for driving units and mechanical components
Solution Approach 1:
The sliding structure is nested within the fixed structure, with the display panel integrated into the sliding mechanism. The driving unit is disposed within the housing and connected to the sliding structure, allowing compact arrangement of components while enabling display area expansion through relative sliding motion between the fixed and sliding structures
Solution Approach 2:
The display structure transitions from a static configuration to a dynamic one, where the sliding structure can move relative to the fixed structure to change the exposed display area. The driving unit enables controlled motion between the two structures, allowing the display to expand or reduce based on user needs while maintaining structural integrity
2Adaptability or versatility
If a driving unit is added to enable sliding motion, then the display can be expanded or reduced, but the mounting space is reduced due to the additional components
Solution Approach 1:
The driving unit is merged with the housing structure, where the housing serves as both the enclosure and the mounting platform for the driving mechanism. The fixed structure and sliding structure are integrated with the driving unit such that the driving force is transmitted through the existing structural components, reducing the need for separate mounting elements and optimizing space utilization
3Volume of stationary object
If the driving unit is disposed on the rear surface of the sliding structure, then the mounting space is optimized, but the ease of operation may be affected
Solution Approach 1:
The sliding structure acts as an intermediary between the user's input and the display expansion function. When the user slides the display or the sliding structure, the motion is transmitted through the driving unit disposed on the rear surface of the sliding structure, which converts the sliding motion into the appropriate mechanical action to expand or reduce the display area, maintaining operational intuitiveness while optimizing internal space
