Interlocking Tray Mechanism for Dual-Point Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing interlocking devices for trays in supporting structures often require simultaneous locking and unlocking of multiple devices to ensure secure installation and removal, which can lead to damage if not done correctly.
Innovation Solution
An interlocking device with a handle, cam, lever, and retractable pin mechanism that securely engages and disengages the tray at two locations, allowing for easy insertion and removal by rotating the handle to selectively lock or unlock the mechanism from recesses in the supporting structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple locking devices are used to secure the tray, then the security and reliability of the tray installation is improved, but the complexity of the device increases and the ease of operation deteriorates
Solution Approach 1:
The patent combines multiple locking devices into a single integrated interlocking mechanism where a first locking device and a second locking device are connected through a common lever system. When the handle is rotated, both locking devices are actuated simultaneously through the lever, allowing one operator to secure both locking points with a single motion, thus improving ease of operation while maintaining the reliability of dual-point securing.
2Reliability
If multiple locking devices are used to secure the tray, then the security of the tray installation is improved, but the device complexity increases
Solution Approach 1:
The patent merges multiple locking devices into a single integrated mechanism where the first locking device and second locking device share a common lever and handle assembly. This consolidation reduces the number of independent components and control elements, thereby reducing device complexity while maintaining the security benefits of engaging multiple locking points simultaneously.
3Productivity
If the tray is quickly removed from the supporting structure, then the productivity is improved, but the risk of damage to the tray and components increases
Solution Approach 1:
The patent implements a preliminary action mechanism where the handle must be rotated to a specific unlocked position before the tray can be removed. This preliminary unlocking action ensures that both locking devices are disengaged in a controlled manner before the tray is pulled out, preventing sudden or forced removal that could cause damage. The operator must consciously perform the unlocking step, which provides a safety buffer against accidental damage while still enabling quick removal when properly executed.
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
Ensures the tray is securely locked in place during insertion and easily removable by disengaging from both recesses, preventing damage to the tray and its components during operation.
Implementation Method 1
a cam connected to the handle through an axle
Implementation Method 2
a lever rotatable about a pivot point on the tray that engages the cam at a first end

AI summary
The interlocking device for a tray in a supporting structure while enabling the tray to be removed from the supporting structure. The tray can include a device that engages with at least one engaging device in the supporting structure. The tray is inserted into the supporting structure using the guide or other engaging device. When the tray is fully inserted into the supporting structure, the tray can be secured to the supporting structure by the interlocking device. The interlocking device secures the tray to the supporting structure by a locking mechanism that selectively engages a first recess and a handle that selectively engages a second recess in the supporting structure. When the tray is to be removed from the supporting structure, the interlocking device disengages from the first and second recesses and enables the tray to be removed without interference of the tray and the supporting structure.
