Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current conveyor systems for processing food products face safety hazards, noise issues, and sanitation challenges due to the use of clamps for securing screens, which also lead to increased maintenance and labor costs.
Innovation Solution
A magnetically secured screen assembly that employs magnetic coupling forces to retain screens within the conveyor support structure, eliminating the need for clamps and allowing for safer, quieter, and more efficient screen changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If clamps are used to secure screens in the conveyor, then the screens can be retained during operation, but operator safety is compromised due to exposure to hot product, steam, and moving parts
Solution Approach 1:
The patent replaces the mechanical clamp system with a magnetic field-based retention system. Magnets embedded in the conveyor sidewalls securely hold the metal screens during operation without requiring operators to manually manipulate clamps, thereby eliminating exposure to hot surfaces, steam, and moving mechanical parts while maintaining reliable screen retention.
Solution Approach 2:
The magnetic field acts as an intermediary force between the conveyor structure and the screens. Instead of direct mechanical contact through clamps, the magnetic field provides the retaining force, allowing screens to be secured without physical intervention from operators during conveyor operation.
2Reliability
If clamps are used to secure screens, then screens can be retained, but noise levels increase due to rattling during operation
Solution Approach 1:
The magnetic retention system eliminates the mechanical clamp components that cause rattling and noise during conveyor operation. The magnetic field provides continuous, vibration-free retention of screens, significantly reducing noise levels while maintaining secure screen positioning.
3Reliability
If clamps are used to secure screens, then screens can be retained, but sanitation is compromised due to crevices accumulating cooking oil residue and particulate
Solution Approach 1:
Replacing the clamp mechanism with a magnetic field eliminates the crevices, joints, and small surfaces where cooking oil and particulate accumulate. The magnetic retention system has no physical contact points with the screens that could trap food residues, thereby improving sanitation and food safety while maintaining screen retention.
4Reliability
If clamps are used to secure screens, then screens can be retained, but maintenance costs increase due to wear and stress fatigue of the clamps
Solution Approach 1:
The magnetic retention system eliminates mechanical clamps that are subject to wear, stress fatigue, and failure from repeated opening and closing operations. The magnetic field requires no physical contact or mechanical movement, resulting in no wear and significantly reduced maintenance requirements while maintaining reliable screen retention.
Solution Approach 2:
The magnetic retention system is self-regulating and requires no active control or adjustment mechanisms. The magnetic field automatically maintains the screens in position during conveyor operation without requiring operator intervention or mechanical adjustment, eliminating the maintenance associated with clamp mechanisms.
5Reliability
If clamps are used to secure screens, then screens can be retained, but operational time is reduced due to the time required to manually open and close clamps during screen changes
Solution Approach 1:
The magnetic retention system allows for rapid screen changes by simply removing the magnetic field's influence (e.g., by moving the screen horizontally out of the magnetic field zone or deactivating the magnets), eliminating the time-consuming process of manually opening and closing clamps while maintaining secure retention during operation.
