Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional magnetic fasteners are used to attach baking pans to racks, then magnetic attachment is achieved, but the fasteners are difficult to attach and detach, and magnets are exposed to wear, corrosion and oxidation
Solution Approach 1:
The fastening assembly is divided into separate components: an E-plate with cantilevered arms that attaches to the rack, and a separate magnetic element that attaches to the pan. This segmentation allows the magnetic component to be easily attached and detached while the E-plate remains fixed to the rack, resolving the contradiction between reliable magnetic attachment and ease of operation.
Solution Approach 2:
The E-plate with cantilevered arms serves as an intermediary between the rack and the magnetic fastener. The arms receive and retain the magnetic element, protecting it from direct exposure to wear and corrosion while maintaining the magnetic attachment function. This intermediary structure enables easy attachment/detachment of the magnetic component without compromising magnetic strength.
2Ease of operation
If magnets are exposed to the environment for fastening, then fastening function is achieved, but magnets suffer from wear, corrosion and oxidation leading to degradation
Solution Approach 1:
The E-plate structure with cantilevered arms provides protective enclosure for the magnetic element before corrosion or wear can occur. The arms create a retained space that shields the magnet from environmental factors, preventing degradation while maintaining the fastening function. This beforehand protection ensures magnetic strength is preserved throughout the service life.
3Ease of manufacture
If simple magnetic fasteners are used, then manufacturing is simplified, but assembly becomes difficult and magnets are exposed to degradation
Solution Approach 1:
The invention merges the attachment function and magnetic fastening function into a single integrated E-plate assembly. The cantilevered arms and magnetic element are combined in one structure that attaches to the rack, simplifying both manufacturing and assembly while protecting the magnet. This merging eliminates the need for separate attachment mechanisms, reducing overall device complexity.
