Rollable Display Multi-Bar Structure Without Battery-Space Hooks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with rollable displays face challenges in achieving larger screen sizes due to fixed display structures, which can lead to reduced battery capacity and lifting or delamination issues.
Innovation Solution
A multi-bar structure with a guide plate and guide rail system supports the display, allowing it to slide while maintaining battery capacity by eliminating hook structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hook structure is added to the multi-bar structure to reduce display lifting, then display stability is improved, but battery volume is reduced
Solution Approach 1:
The patent extracts the harmful hook structure from the multi-bar structure while retaining the essential support function through alternative means (multi-bar structure with guide plate), thereby eliminating the conflict between display stability and battery volume
Solution Approach 2:
The guide plate acts as an intermediary component between the multi-bar structure and the display, providing the necessary guidance and support without requiring the hook structure that would otherwise encroach on battery space
2Area of moving object
If the display size is increased to support multimedia services, then user experience is improved, but device size increases
Solution Approach 1:
The patent employs a dynamic multi-bar structure with guide plate that enables the display to expand and contract along the sliding direction, allowing the display area to change without permanently increasing the device footprint
Solution Approach 2:
The invention utilizes the sliding direction (third dimension relative to the display plane) to accommodate the larger display area, allowing the display to extend beyond the device boundaries when needed while maintaining a compact form factor when retracted
3Reliability
If a conventional multi-bar structure with hook is used to support the display, then display support is improved, but battery capacity is reduced
Solution Approach 1:
The patent removes the hook structure from the multi-bar design, extracting the problematic element that reduced battery capacity while preserving the display support function through the guide plate mechanism
Solution Approach 2:
The invention changes the structural parameters of the support system by transitioning from a hook-based conventional multi-bar structure to a guide plate-integrated multi-bar structure, thereby increasing battery capacity while maintaining support reliability
