Industrial Hook Lock Block for Secure Workpiece Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hook and rack systems for industrial coating processes are expensive, complex, and labor-intensive to install and maintain, and they pose safety risks due to the need for manual handling of metal wires.
Innovation Solution
A hook lock system comprising a block with a passageway and concave depressions on either side, which is frictionally retained on the hook shank, preventing the workpiece from disengaging during transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex and expensive hook and rack systems are used to lock the workpiece in place, then the workpiece is securely retained during transport, but the system becomes expensive to design, manufacture, install, and maintain
Solution Approach 1:
The complex hook and rack locking system is segmented into a simple, separate component: the block. This block can be independently attached to the rack and functions as a standalone locking element, eliminating the need for complex integrated systems while maintaining workpiece retention reliability
Solution Approach 2:
The invention uses a simple, inexpensive block that can be easily replaced rather than maintaining complex, expensive hook and rack systems. The block serves as a disposable or easily replaceable component that provides reliable retention without the ongoing maintenance costs of complex systems
2Reliability
If metal wires are used to tether the workpiece to the rack, then the workpiece is secured during transport, but the installation and removal processes become laborious and dangerous for workers
Solution Approach 1:
The manual mechanical process of twisting and securing metal wires is replaced with a simpler mechanical system: the block with passageway that allows the hook to pass through and lock automatically, eliminating the need for manual wire manipulation and associated safety risks
Solution Approach 2:
The block system is self-servicing in that the hook passing through the passageway automatically creates the locking action without requiring worker intervention for twisting or securing, making the process safer and easier to perform
3Reliability
If custom hook and rack systems are designed for each workpiece, then the workpiece is securely retained, but the systems take up valuable warehouse space and require extensive maintenance
Solution Approach 1:
The block is designed as a universal component that can be used with various hook and rack configurations and different workpiece types. Instead of maintaining multiple custom systems for different workpieces, a single block design serves multiple functions and applications, reducing warehouse storage requirements
Solution Approach 2:
The invention merges the locking function into a single, compact block component that integrates with existing rack structures, eliminating the need for separate, space-consuming custom hook and rack systems for each workpiece type
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 lock system effectively retains the workpiece on the hook without the need for complex or expensive systems, reducing production downtime, inventory loss, and safety hazards, while being simple to use and inexpensive to manufacture.
Implementation Method 1
The passageway has a cross-sectional width less than or equal to the cross-sectional width of the shank such that the block is frictionally retained on the shank of the hook

AI summary
A hook lock and method are provided for retaining a workpiece on a hook of an industrial rack. The hook includes a shank having a cross-sectional width, defining a bend for receiving the workpiece thereon, and terminating at a terminal end. The hook lock includes a block having a passageway extending along an axis between first and second outer surfaces of the block. The passageway has a cross-sectional width less than or equal to the cross-sectional width of the shank. In operation, the hook is inserted through the workpiece, and thereafter, through the passageway in the block such that the block is frictionally retained on the shank of the hook. The block prevents the workpiece from being disengaged from the hook as the workpiece is transported along a line.
