Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable electronic devices face issues with conductive plates that cannot be folded, leading to folding marks and operational malfunctions due to separate disposition, which deteriorate reliability and increase production costs.
Innovation Solution
A foldable conductive plate design with flexible and flat portions connected by adhesive members, allowing it to bend with the display, integrated with polymer members and reinforcing plates for support, ensuring seamless folding without marks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the eject bar is disposed to overlap with the tray body when viewed from above, then the eject bar can be disposed at a shorter length, but it may contact the distal end of the tray body and fail to transmit ejecting force when the tray is fully ejected
Solution Approach 1:
The patent changes the spatial arrangement from a top-down overlap configuration to a side-by-side configuration where the eject bar is disposed adjacent to the tray body rather than overlapping it when viewed from above. This dimensional repositioning allows the eject bar to maintain sufficient length for reliable force transmission while still achieving compact overall device dimensions through optimized spatial layout.
2Stability of the object's composition
If the rotation lever presses the tray at the distal end, then the tray can be stably received on the eject bar, but the eject bar must be longer which increases device volume
Solution Approach 1:
The patent repositions the rotation lever to press the tray body at a location adjacent to the eject bar rather than at the distal end. This spatial reconfiguration allows the tray to be stably received on the eject bar while using a shorter eject bar length, thereby reducing the overall device volume while maintaining stability.
3Reliability
If the eject bar is disposed away from the tray body, then the eject bar can be longer for stable tray reception, but it increases the overall device volume
Solution Approach 1:
The patent employs a rotation lever that can rotate about a pivot point to dynamically adjust the pressing position on the tray body. This dynamic mechanism allows the system to achieve stable tray reception with a shorter eject bar by utilizing the rotational motion to apply force at the optimal position, thereby reducing device volume while maintaining reliability.
