Solution Overview

Problem

Existing industrial baking pans face issues with hygiene contamination due to metal dust from rivet holes, require skilled labor for assembly, and suffer from insert damage and slow replacement processes.

Innovation Solution

An attachment system using clip fasteners that snap onto the frame bars, allowing easy and safe assembly and disassembly of interchangeable inserts without damaging the frame or insert, ensuring hygiene and reducing replacement time and cost.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If rivets are used to fix the insert to the frame, then the insert is securely attached, but metal dust contaminates the baked goods and hygiene cannot be ensured

Engineering Contradiction:

Improveattachment strengthVSAvoidmetal dust contamination

Core Design Contradiction:

StrengthVSObject-affected harmful factors

Solution Approach 1:

The invention extracts the harmful rivet holes from the frame structure and replaces them with surface-mounted clip fasteners that attach to the insert without penetrating the frame, thereby eliminating the source of metal dust contamination while maintaining attachment functionality

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The clip fastener acts as an intermediary component between the frame and insert, providing a secure attachment mechanism that does not require drilling holes in the frame, thus preventing metal dust generation while ensuring strong connection

Inventive Principle:

Principle #24Intermediary (Mediator)

2Strength

If rivets are used to attach the insert, then the insert is fixed, but skilled labor is required for assembly and disassembly

Engineering Contradiction:

Improveattachment strengthVSAvoidassembly ease

Core Design Contradiction:

StrengthVSEase of operation

Solution Approach 1:

The clip fasteners are designed to be manually installed and removed by operators without requiring specialized skills or tools, enabling maintenance personnel to independently perform insert replacement operations

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The invention removes the complex riveting process requiring skilled labor and replaces it with simple clip fastener attachment that can be performed by unskilled workers through basic manual operations

Inventive Principle:

Principle #2Taking out (Extraction)

3Strength

If the insert is deformed to fold around the frame, then the insert is attached to the frame, but the insert may be damaged or broken after several bending cycles

Engineering Contradiction:

Improveattachment strengthVSAvoidinsert durability

Core Design Contradiction:

StrengthVSReliability

Solution Approach 1:

The invention segments the attachment function into separate components: the frame remains rigid and undamaged, while independent clip fasteners provide the attachment mechanism, eliminating repeated bending of the insert itself

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The clip fastener serves as an intermediary that provides the necessary deformation and flexibility for attachment, protecting the insert from direct bending and mechanical damage during repeated assembly cycles

Inventive Principle:

Principle #24Intermediary (Mediator)

4Strength

If the insert is deformed to fold around the frame, then the insert is attached, but the process is slow and requires specific tools and skilled labor

Engineering Contradiction:

Improveattachment strengthVSAvoidinsert replacement speed

Core Design Contradiction:

StrengthVSProductivity

Solution Approach 1:

The clip fasteners are designed for simple manual installation without requiring specialized tools or skilled labor, enabling rapid insert replacement that increases productivity

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The invention extracts the complex folding and bending operations from the attachment process and replaces them with simple clip fastener attachment, dramatically reducing assembly time and eliminating the need for specialized tools

Inventive Principle:

Principle #2Taking out (Extraction)

5Strength

If rivet holes are drilled in the frame profiles, then the insert can be attached, but dirt and washing liquids penetrate into the profiles and accumulate, contaminating baked goods

Engineering Contradiction:

Improveattachment strengthVSAvoidcontamination from accumulated dirt

Core Design Contradiction:

StrengthVSObject-affected harmful factors

Solution Approach 1:

The invention extracts the attachment mechanism from the frame interior and positions it on the exterior surface, eliminating holes that would allow dirt and washing liquids to penetrate and accumulate inside the frame profiles

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The clip fastener acts as an external intermediary attachment mechanism that secures the insert without creating openings in the frame structure, thereby preventing contamination pathways while maintaining secure attachment

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

An industrial baking pan with an interchangeable insert, includes a perimeter frame including a plurality of bars joined together, an interchangeable insert delimiting a support surface for a product to be baked and removably attachable to the perimeter frame, clip fasteners connected or connectable to the interchangeable insert. Each clip fastener is snap-on engaged or engageable astride one of the bars of the perimeter frame and a cross-section of the bar has seats configured to snap the clip fastener in place.
