Solution Overview

Problem

Existing baking devices require complex and labor-intensive processes for replacing individual baking molds, as the hook-like fold ends are designed for permanent attachment, making frequent changes impractical.

Innovation Solution

The implementation of latching devices with resilient lugs and frame legs, where latching bodies engage in latching recesses, allowing for easy insertion and secure mounting of baking molds, and a tool-accessible recess for easy release.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If hook-like fold ends are used to clamp baking molds to the frame, then secure mounting is achieved, but the replacement process becomes complex and labor-intensive

Engineering Contradiction:

Improvesecure mountingVSAvoidreplacement process

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The connection system is divided into separate functional elements: resilient lugs with latching bodies on the baking mold, and corresponding latching recesses in the frame. This segmentation allows the mold to be securely latched during operation while enabling quick release by simply pulling the mold upward, eliminating the complex manipulation required by hook-like fold ends.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Instead of using a active clamping mechanism (hook-like fold ends that must be manually manipulated to release), the invention uses a passive retention mechanism where the baking mold is held by latching bodies that automatically engage with latching recesses. The mold is released by simply lifting it, inverting the operation from active release to passive release-through-removal.

Inventive Principle:

Principle #13The other way round (Inversion)

2Ease of operation

If latching bodies engage in latching recesses for automatic latching, then handling effort is reduced, but the risk of unintentional release increases

Engineering Contradiction:

Improvehandling effortVSAvoidunintentional release

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The resilient lugs are designed to extend beyond the frame when the baking mold is inserted, with the latching bodies engaging in latching recesses. This extraction of the lugs beyond the frame creates a physical barrier that prevents unintentional release, as the lugs must be deliberately pulled back to disengage the latching mechanism.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The resilient lugs are pre-positioned to extend beyond the frame and engage the latching recesses before any release action can occur. This preliminary engagement creates a mechanical interlock that must be actively broken to release the mold, preventing accidental disengagement during normal handling.

Inventive Principle:

Principle #9Preliminary anti-action

3Extent of automation

If resilient tabs are used for insertion, then automatic latching is ensured, but the tabs must be deflected for release which complicates the release process

Engineering Contradiction:

Improveautomatic latchingVSAvoidrelease process

Core Design Contradiction:

Extent of automationVSEase of operation

Solution Approach 1:

Instead of requiring active manipulation to engage the resilient tabs (which would complicate insertion), the design allows the tabs to automatically engage during normal insertion. The release process is simplified by inverting the mechanism: rather than actively disengaging the tabs, the mold is simply lifted, and the tabs passively follow and disengage as the mold is removed.

Inventive Principle:

Principle #13The other way round (Inversion)

AI summary

The invention describes a baking apparatus having a plurality of baking moulds (2) which can be inserted into a frame (1) from above and which have clips (5) which extend over mutually opposite limbs (3) of the frame (1). In order to be able to replace individual baking moulds (2) in a simple manner, without having to break the secure holding of the baking moulds (2) in the frame (1), it is proposed that latching devices with latching bodies (8) which engage in latching cutouts (7) are provided between the clips (5), which are of resilient design, and the frame limbs (3) over which the clips (5) extend.
