Load-Actuated Latch Hook for Secure Assembly Line Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hooks used in transport systems for assembly lines often fail to securely couple components to conveyors, leading to shifting or decoupling issues due to inadequate securing mechanisms.
Innovation Solution
A hook design featuring a latch that pivots between open and closed positions in response to a load, ensuring secure engagement with the component by aligning a chain aperture with an elongate aperture, and utilizing a biasing element to maintain the latch in an open position until a load is applied, causing it to pivot and occlude the hook opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple hook design is used, then the device complexity is reduced, but the reliability of secure coupling deteriorates
Solution Approach 1:
The latch is designed to dynamically transition between open and closed positions based on load conditions. When no load is applied, the latch remains open for easy component insertion. When load is applied, the latch automatically pivots to the closed position to secure the component, providing adaptive security without complex control systems.
Solution Approach 2:
The hook mechanism is self-activating through load-induced pivoting. The chain aperture alignment and load application automatically trigger the latch to pivot and occlude the hook opening, securing the component without requiring external actuators, sensors, or control systems.
2Reliability
If a secure latch mechanism is added, then the reliability of coupling is improved, but the ease of operation deteriorates
Solution Approach 1:
The latch transitions from a static blocked state to a dynamic load-responsive state. During insertion, the latch is naturally held in the open position, allowing free component access. Once the component is inserted and load is applied, the latch automatically moves to the closed position, providing security without impeding the insertion process.
Solution Approach 2:
The latch is pre-configured in an open position that allows easy component insertion. The securing action is prepared in advance through the alignment of the chain aperture, so that when load is applied, the latch is already positioned to pivot and secure the component immediately.
3Ease of operation
If the latch is held open for easy access, then the ease of operation is improved, but the reliability of preventing de-coupling deteriorates
Solution Approach 1:
The latch system dynamically adapts its state based on operational conditions. During loading and insertion phases, the latch remains open for accessibility. During transport and load-bearing phases, the latch automatically transitions to the closed position to prevent de-coupling, providing context-appropriate behavior.
Solution Approach 2:
The latch is designed to counteract the de-coupling force before it can cause failure. When load is applied, the latch pivots to occlude the hook opening, creating a preventive barrier against de-coupling that activates exactly when needed to counteract the opening forces.
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 hook effectively prevents de-coupling of components during transport by securely closing the hook opening when a load is applied, ensuring stable and reliable movement along the assembly line.
Implementation Method 1
The latch defines a chain aperture that is aligned with the elongate aperture such that the portion of the chain extends through each of the elongate aperture and the chain aperture and causes the latch to pivot between the first and second positions in response to a load being applied to the hook.

AI summary
A hook for lifting a component includes a hook body and a latch. The hook body includes a coupling portion having an elongate aperture defined therein for receiving at least a portion of a chain, and an engaging portion extending from the coupling portion, the engaging portion defining a hook opening sized for receiving a first portion of the component therein. The latch is pivotably coupled to the coupling portion and pivotable between a first position and a second position relative to the hook body. The latch occludes the hook opening in the second position. The latch defines a chain aperture that is aligned with the elongate aperture such that the portion of the chain extends through each of the elongate aperture and the chain aperture and causes the latch to pivot between the first and second positions in response to a load being applied to the hook.
