Movement control device for part assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing furniture and device systems fail to prevent movable parts from unintentionally opening during earthquakes or tilts, leading to potential damage or ejection, which can cause harm to people or objects.
Innovation Solution
A movement control device comprising a first blocking member, a supporting plate, and a second blocking member, where the second blocking member is movable between an initial and blocking position to prevent the second object from moving relative to the first object, thereby maintaining stability during shakes or tilts and allowing safe reopening when the disturbance ceases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a push-open mechanism is arranged on the slide rail assembly to allow the drawer to be easily opened, then the ease of operation is improved, but the reliability deteriorates because the drawer may be ejected unintentionally when the drawer system is shaken, tilted or hit
Solution Approach 1:
The blocking member is preliminarily positioned to block the blocking part before any harmful movement occurs. When the drawer system experiences shaking or tilting, the blocking member is already in place to prevent the drawer from being ejected, countering the harmful effect before it can manifest.
Solution Approach 2:
The blocking member is designed to be movable relative to the supporting plate, allowing it to dynamically adjust its position. It can move from an initial blocking position to a second position that allows normal drawer operation, and return to the blocking position when needed, providing both safety and operational functionality.
2Reliability
If a blocking member is arranged to prevent the drawer from being ejected during shaking, then the reliability is improved, but the ease of operation deteriorates because the drawer cannot be opened when needed
Solution Approach 1:
The blocking member transitions from a static blocking structure to a dynamic one that can move between positions. When the drawer needs to be opened, the blocking member moves from the first position (blocking the blocking part) to the second position (allowing movement), enabling normal operation while maintaining safety capabilities.
Solution Approach 2:
The blocking member acts as an intermediary element between the drawer and the slide rail assembly. It mediates between the conflicting requirements of preventing ejection and allowing operation by selectively engaging or disengaging from the blocking part based on the operational state.
3Reliability
If the blocking member is always in the blocking position to prevent ejection, then the reliability is improved, but the productivity deteriorates due to loss of time for opening and closing operations
Solution Approach 1:
The blocking member dynamically adjusts its position based on operational needs. It remains in the blocking position only when disturbance is detected, and moves to the non-blocking position during normal operation, minimizing the time impact on productivity while maintaining safety when required.
Solution Approach 2:
The blocking member alternates between blocking and non-blocking states based on the operational cycle. It blocks during potential disturbance periods and releases during normal operation periods, creating a periodic pattern that balances safety and productivity requirements.

AI summary
A movement control device (24) is applicable to a first object (20) and second object (22) movable relative to the first object (20). One of the first object (20) and the second object (22) is arranged with a first blocking part (28a) and a second blocking part (28b); and the other one of the first object (20) and the second object (22) is movably arranged with a blocking member (30) . When the second object (22) is moved relative to the first object (20) and the blocking member (30) is moved from an initial position to a blocking position, the blocking member (30) is configured to block one of the first blocking part (28a) and the second blocking part (28b), in order to prevent the second object (22) from being moved relative to the first object (20).
