Slide-Type Portable Device Correction Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional slide-type portable computers experience uneven and non-smooth sliding due to longer and farther-apart slide rails, leading to inconvenient two-handed operation and potential sticking issues.
Innovation Solution
Incorporation of correction mechanisms with push-back members and a buffer mechanism to guide and stabilize the sliding housing, ensuring smooth one-handed operation and reducing impact during closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the slide rails are made longer and farther apart to accommodate larger portable computers, then the device size is increased, but the sliding becomes uneven and non-smooth
Solution Approach 1:
The patent introduces correction mechanisms as intermediary components between the slide rails and the sliding housing. These correction mechanisms include correction members that can adjust the position of the slide rails, acting as mediators to ensure smooth sliding even when the rails are long and far apart. The correction mechanisms compensate for the increased distance and potential misalignment issues.
Solution Approach 2:
The correction mechanisms provide feedback control for the sliding operation. When the sliding housing deviates from the intended path, the correction members detect this deviation and automatically adjust the slide rail position to correct the trajectory, ensuring smooth and accurate sliding movement throughout the entire range of motion.
2Volume of moving object
If the slide rails are longer and farther apart, then the device can be larger, but the sliding housing may deviate and get stuck
Solution Approach 1:
The correction mechanisms serve as intermediary components that maintain reliable sliding by continuously monitoring and adjusting the slide rail position. The correction members act as mediators between the sliding housing and the slide rails, ensuring that the housing follows the correct path and preventing sticking even over long distances.
Solution Approach 2:
The correction mechanisms perform preliminary adjustments to the slide rail position before the sliding housing reaches problematic areas. By proactively correcting potential deviations before they cause the housing to get stuck, the system maintains reliable sliding operation throughout the entire range of motion.
3Device complexity
If no correction mechanisms are used, then the device structure is simpler, but one-handed operation becomes difficult
Solution Approach 1:
The correction mechanisms are designed to automatically correct sliding deviations without requiring user intervention. The system serves itself by detecting and correcting misalignment issues autonomously, allowing users to operate the device easily with one hand while the correction mechanisms handle the complex alignment adjustments in the background.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates one-handed operation by maintaining smooth sliding and reducing the force required to open and close the device, while preventing large impacts through buffering and shock-absorbing functions.
Implementation Method 1
Each of the correction mechanisms includes at least two spaced-apart push-back members arranged along the sliding direction. When the slide rails deviate from the sliding direction, the push-back members can push back the slide rails to a position parallel to the sliding direction
Implementation Method 2
the buffer mechanism ensures that the speed of the sliding housing when reaching the closed position is not too fast, a large impact among the positioning components can be prevented
Implementation Method 3
the buffer mechanism can produce a resilient force the moment the sliding housing is opened to assist in pushing the sliding housing to slide toward the open position
Data Source
AI summary
A portable electronic device includes superposed base and sliding housings, a pair of guide units and a pair of slide rails that cooperate with each other to permit sliding movement of the sliding housing relative to the base housing along a sliding direction between closed and open positions, and a pair of correction mechanisms respectively adjacent to the slide rails and each including at least two push-back members. When the slide rails deviate from the sliding direction, the push-back members can push back the slide rails to a position parallel to the sliding direction so that the slide rails can slide smoothly relative to the guide units.
