Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slide assembly systems face issues with failure of rectilinear movement between moving units and cabinets after push-to-eject operation, and incomplete closure due to lack of proper movement restriction mechanisms.
Innovation Solution
A movement restricting apparatus comprising a track unit with non-limit and limit paths, a restricting unit with a pivotally mounted pin unit, and a biasing unit using resilient members to guide the pin unit's movement unidirectionally, ensuring proper alignment and complete closure of the moving unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mechanical push-to-eject operation is used to open the moving unit, then the moving unit can be easily opened, but the moving unit may fail to move rectilinearly due to lack of movement restriction
Solution Approach 1:
A pin unit is introduced as an intermediary component between the moving unit and the guide track. The pin unit engages with the guide track to restrict and guide the movement of the moving unit, ensuring rectilinear motion while allowing easy push-to-eject operation. The pin unit acts as a mediator that translates the simple pushing action into controlled rectilinear movement.
Solution Approach 2:
The guide track is segmented into different functional regions: a non-limit path for easy movement, a limit path for rectilinear restriction, and a turning region for directional change. This segmentation allows the moving unit to experience different movement constraints in different phases of operation, ensuring both ease of opening and reliable rectilinear movement.
2Device complexity
If no movement restriction mechanism is provided, then the structure is simple, but the moving unit cannot close completely and may stay at the push-to-eject position
Solution Approach 1:
The pin unit serves as a minimal yet effective intermediary that provides the necessary movement restriction. By engaging with the guide track, it ensures complete closure without requiring a complex restriction mechanism. The simple pin-unit-guide track interaction achieves reliable closure while maintaining structural simplicity.
Solution Approach 2:
The pin unit is designed to pivot relative to the moving unit, providing dynamic adaptation during operation. This pivoting capability allows the pin unit to engage and disengage smoothly with the guide track, ensuring complete closure while avoiding excessive structural complexity.
3Device complexity
If the pin unit is fixed rather than pivotally mounted, then the structure is simpler, but the pin unit cannot adapt to movement variations and may cause binding
Solution Approach 1:
The pin unit is pivotally mounted rather than fixed, allowing it to adapt dynamically to movement variations. This pivoting capability enables smooth operation by accommodating slight misalignments and movement inconsistencies without causing binding, while adding minimal mounting complexity.
Solution Approach 2:
The pivotal mounting allows the pin unit to change its angular parameter during operation, adapting to the movement requirements of the moving unit. This parameter change capability ensures smooth operation while maintaining relatively simple mounting structure.
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
The apparatus ensures reliable unidirectional movement and complete closure of the moving unit by engaging the pin unit with the guide track, preventing reverse movement and allowing synchronized operation across both sides, thus addressing the issues of incomplete closure and failure of rectilinear movement.
Implementation Method 1
The biasing unit has a resilient member adapted to be disposed between the stationary unit and the moving unit

AI summary
A movement restricting apparatus includes a track unit with a guide track that has a non-limit path and a limit path, and a restricting unit with a pin unit that has a pin portion. The pin portion is swingably inserted into the guide track. The pin portion and the guide track make relative movement when a moving unit moves relative to a stationary unit. The relative movement of the pin portion and the guide track is guided by the limit path when the moving unit moves in a first direction and is guided by the non-limit path when the moving unit moves in a second direction opposite to the first direction.
