Interchangeable Polymer Hooks for Food Conveyor Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing food-manufacturing systems with metal hooks are poorly suited to handle delicate and high-value products, and are difficult to adapt to different product and process requirements, leading to inefficiencies and increased costs due to the need for frequent reconfiguration and potential damage from sharp hooks that deform over time.
Innovation Solution
An interchangeable hook-and-bracket system where metal brackets provide secure attachment to the conveyor and polymer-based hooks are designed to be flexible, blunt, and resistant to deformation, allowing easy replacement based on product or process needs without compromising connection strength, and featuring engagement features for intuitive attachment and confirmation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If metal hooks are used to provide secure attachment to the conveyor, then connection strength is improved, but the hooks become sharp and deform over time causing product damage
Solution Approach 1:
The hook system is divided into two separate components: a metal bracket that attaches to the conveyor and a polymer hook that attaches to the bracket. This segmentation allows each component to be optimized for its specific function - the metal bracket provides secure attachment while the polymer hook provides gentle product handling.
Solution Approach 2:
The polymer hook acts as an intermediary between the metal bracket and the product. It transfers the attachment function from the metal bracket to the product while protecting the product from direct contact with sharp metal edges.
2Adaptability or versatility
If the entire conveyor system is replaced to accommodate different product dimensions, then adaptability to different products is improved, but reconfiguration time and cost increase
Solution Approach 1:
The hook system is segmented into interchangeable polymer hooks and fixed metal brackets. Only the polymer hooks need to be changed when switching products, not the entire conveyor system. This reduces reconfiguration time and complexity.
Solution Approach 2:
The metal brackets are designed with universal engagement features that can accommodate multiple types of polymer hooks with different dimensions and configurations. This allows a single bracket design to support various product sizes and types.
3Reliability
If metal hooks are designed to prevent unintended disengagement, then connection reliability is improved, but the hooks become difficult to disengage for reconfiguration
Solution Approach 1:
The connection system is segmented into two engagement interfaces: a strong permanent engagement between the metal bracket and conveyor, and a reversible engagement between the polymer hook and bracket. This allows reliability where needed while maintaining ease of reconfiguration.
Solution Approach 2:
Different engagement characteristics are applied to different parts of the system. The bracket-conveyor interface uses strong, non-releasable engagement for reliability, while the bracket-hook interface uses weaker, releasable engagement for ease of operation.

AI summary
An interchangeable hook-and-bracket system for a manufacturing process is disclosed. The interchangeable hook-and-bracket system may be configured to cooperate with a vertical conveying system of a food-processing system. Interchangeable hooks of the conveyor system may comprise hook portions and bracket portions that may be configured to releasably attach to one another. The bracket portions may be made substantially of a structurally robust material such as a metal and may be non-releasably attached to the conveyor system, and the hook portions may be made substantially of a flexible material such as a polymer-based material. More than one hook portion may correspond to a bracket portion, each hook portion having a configuration corresponding to a particular product, casing, throughput, and/or process condition.
