Solution Overview

Problem

Longer chutes in stackable units for cooking ham lack the necessary rigidity to maintain a constant section along their length, leading to potential buckling under weight and inconsistent cooking conditions.

Innovation Solution

Incorporation of vertical columns on each longitudinal profile to enhance rigidity and alignment studs for precise stacking, ensuring a constant section between the chute and lid across the stackable units.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of moving object

If the length of chutes is increased to accommodate larger hams, then the cooking capacity is improved, but the rigidity of the frame deteriorates causing buckling under weight

Engineering Contradiction:
Improvechute lengthVSAvoidframe rigidity
Core Design Contradiction:
Length of moving objectVSStrength

Solution Approach 1:

The frame is segmented into multiple longitudinal profiles (at least three) distributed along the chute length. Each profile acts as an independent structural element, distributing the load and preventing buckling while accommodating longer chutes for larger hams.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Transverse sections are introduced as intermediary elements connecting the longitudinal profiles. These transverse sections provide additional structural support and rigidity to the frame, preventing buckling of individual longitudinal profiles under the weight of long hams.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of manufacture

If folded sheet longitudinal profiles are used to simplify manufacturing, then the ease of manufacture is improved, but the manufacturing precision deteriorates as constant section cannot be guaranteed

Engineering Contradiction:
Improveframe constructionVSAvoidconstant section maintenance
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

The frame is divided into multiple longitudinal profiles (at least three) that are distributed along the chute. This segmentation allows each profile to maintain its shape independently, ensuring constant section throughout the chute length while still using simple folded sheet construction.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The longitudinal profiles are positioned at specific locations (including at least one at each end and one in the middle) to provide localized structural support. This strategic positioning ensures constant section maintenance in critical areas while keeping the overall construction simple.

Inventive Principle:
Principle #3Local quality

3Ease of operation

If alignment studs with conical ends are used to facilitate stacking, then the ease of operation is improved, but the device complexity increases

Engineering Contradiction:
Improvestacking alignmentVSAvoidalignment mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

Instead of using complex alignment mechanisms, the patent uses simple conical studs that fit into corresponding holes. The conical shape provides self-alignment through geometric constraint, simplifying the stacking operation while maintaining precision.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The conical alignment studs provide self-aligning functionality during stacking. The conical geometry automatically guides the upper stackable unit into correct alignment with the lower unit, eliminating the need for external alignment tools or complex mechanisms.

Inventive Principle:
Principle #25Self-service
