Adjustable Decking Assembly Lever Lock Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing decking systems for cargo are not easily adjustable by a single user, requiring multiple users or complex mechanisms to change the height of the decking system.
Innovation Solution
An adjustable decking system featuring a track with recesses, a pivotably connected channel unit and bracket, a lock with a spring bias, and a lever mechanism that allows a single user to pivot the lock from a locked to a released position, enabling the beam to be lowered by sliding along the track, allowing for height adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional decking system is used, then the structure is stable and strong, but it requires multiple users or complex mechanisms to adjust the height
Solution Approach 1:
The locking mechanism transitions from a static locked state to a dynamic adjustable state through the lever activation sequence. The channel unit can pivot between fixed positions (locked) and movable positions (unlocked), allowing the beam to be dynamically repositioned along the track while maintaining structural integrity during both states
Solution Approach 2:
The adjustment mechanism is divided into discrete functional segments: the lock with finger for engagement, the lever for activation, the spring for resetting, and the channel unit for movement. This segmentation allows each component to perform its specific function independently, simplifying the overall adjustment operation while maintaining reliability
2Reliability
If a simple locking mechanism is used, then the device is easy to operate, but it cannot maintain stable locking positions
Solution Approach 1:
The spring is pre-loaded to store energy that automatically resets the lock finger to the engaged position after lever release. This beforehand cushioning ensures the locking mechanism reliably returns to its stable locked state without requiring manual intervention, maintaining both reliability and ease of operation
Solution Approach 2:
The locking mechanism is self-resetting through the spring's automatic action. After the lever is released, the spring autonomously pushes the lock finger back into engagement with the track, ensuring the beam remains securely locked at the desired position without requiring additional user actions or complex control systems
3Ease of operation
If the lock is always engaged, then the beam is securely held, but the user cannot adjust the height
Solution Approach 1:
The locking mechanism dynamically transitions between engaged and disengaged states based on lever position. During adjustment, the lock is temporarily disengaged to allow beam movement, then automatically re-engages at the new position, providing both adjustability and secure holding without compromising strength
4Measurement precision
If a complex mechanism is used to adjust height, then the beam can be precisely positioned, but it requires multiple users or complex operations
Solution Approach 1:
The positioning system is segmented into discrete stop positions along the track, each corresponding to a specific height. The lock finger engages with these segmented positions to provide precise, repeatable height settings while maintaining simple operation through the single-lever activation mechanism
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
Enables a single user to easily adjust the height of the decking system by pivoting the lock and sliding the beam, ensuring the system can be set to a desired horizontal position efficiently and effectively.
Implementation Method 1
a spring disposed between the lock and the bracket and biasing the lock toward the locked position
Implementation Method 2
a lever pivotably mounted on the bracket, wherein the lever pivots to contact the lock and transfer a force upon the lock via a first end of the lever to pivot the lock from the locked position toward the released position
Implementation Method 3
the bracket slidably mounted upon the track
Implementation Method 4
when the channel unit is pivoted from a horizontal position to an acute angle below the horizontal position
