Solution Overview
Problem
Existing foldable devices require complex operations and risk component interference due to poor design or tolerance, making it inconvenient to switch between folded and unfolded states.
Innovation Solution
A foldable device with a lifting mechanism that utilizes a rail, sliding members, linking members, and a latch structure to enable a single linear motion mode for switching between states, simplifying the operation and reducing component interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional foldable mechanism is used, then the device can be folded and unfolded, but the operation process is complicated and inconvenient
Solution Approach 1:
The patent combines multiple foldable mechanisms into a single integrated structure where the first and second foldable mechanisms are coupled together. The first link member connects both mechanisms, and the second link member couples the first sliding member to the second sliding member, creating a unified system that operates as one unit rather than separate mechanisms.
Solution Approach 2:
The latch structure serves as an intermediary element that controls the relative movement between the first and second sliding members. By engaging or disengaging the latch, the user can easily switch between locked and unlocked states, simplifying the operation of the complex foldable mechanism system.
2Reliability
If a conventional foldable mechanism is used, then the device can be adjusted, but component interference occurs due to poor design or poor component tolerance
Solution Approach 1:
The patent divides the foldable mechanism into distinct modular components: first and second sliding members, first and second link members, and a latch structure. Each component has a specific function and can be independently manufactured and assembled, reducing interference from poor tolerances in any single component.
Solution Approach 2:
Instead of allowing the foldable mechanisms to move freely and relying on tolerances to prevent interference, the patent inverts the approach by using a latch structure to actively control and constrain the movement. The latch positively engages to lock components in place, preventing interference issues that would arise from tolerance accumulation.
3Ease of operation
If multiple components are used for folding, then the folding function is achieved, but the operation process is complicated
Solution Approach 1:
The patent merges the operation of multiple components into a single action. When the user operates the latch structure, it simultaneously controls the relative movement between the first and second sliding members, which in turn coordinates both foldable mechanisms. This reduces the number of separate operations needed despite having multiple components.
Solution Approach 2:
The latch structure serves multiple functions: it locks the sliding members in place, controls the folding operation, and enables easy switching between folded and unfolded states. The first and second link members also serve dual purposes by connecting both foldable mechanisms and providing structural support.

Function Achieved in This Case
The device allows seamless switching between folded and unfolded states through a simple linear motion, enhancing user convenience and reducing the risk of component interference.
Implementation Method 1
the second sliding member has a friction force 1 with respect to the rail, there is a friction force 2 at the pivot joint between the first linking member and the second sliding member, there is a friction force 3 at the pivot joint between the first linking member and the second linking member, and there is friction force 4 at the pivot joint between the second linking member and the first sliding member

AI summary
A foldable device with a lifting mechanism includes at least one rail, a first sliding member, a second sliding member, a first linking member, a second linking member, and a latch structure. The first and the second sliding members are movably disposed on the rail, the first linking member is pivoted to the second sliding member, and the second linking member is pivoted to the first linking member and the first sliding member. The first and the second sliding members are combined with or departed from each other through a latch structure. The first and the second sliding members move closed to or away from each other to drive the first linking member to be folded onto or spread out from the rail when the first and the second sliding members are departed from each other.
