Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If conventional fire pots are designed as solid shell or bowl structures, then they provide structural strength and stability, but they become heavy and require significant storage space

Engineering Contradiction:
Improvestructural strengthVSAvoidweight
Core Design Contradiction:
StrengthVSWeight of stationary object

Solution Approach 1:

The fire pot is divided into multiple planar partitions (typically three) that can be assembled together to form the complete bowl structure. Each partition is a flat element that is lightweight, and when assembled with interlocking connections, they create a structurally sound fire bowl without the weight of a traditional solid construction

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The planar partitions are designed to nest within each other when disassembled, with each partition containing or overlapping with others in a compact arrangement. This nesting capability allows the fire pot to be collapsed into a minimal storage footprint while maintaining full structural integrity when assembled

Inventive Principle:
Principle #7Nested doll (Nesting)

2Strength

If conventional fire pots are designed as solid shell or bowl structures, then they provide structural strength and stability, but they become bulky and require significant storage space

Engineering Contradiction:
Improvestructural strengthVSAvoidstorage space
Core Design Contradiction:
StrengthVSVolume of stationary object

Solution Approach 1:

By segmenting the fire pot into thin planar partitions rather than a solid shell, the volume required for storage is dramatically reduced. The partitions can be flat-packed or nested in a compact configuration that occupies minimal space while still forming a structurally adequate fire bowl when assembled

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The design transitions from a three-dimensional solid bowl to two-dimensional planar elements that can be stored in a flattened or nested state. This dimensional reduction allows the fire pot to collapse from its functional volume to a minimal storage profile, effectively utilizing another dimension (flatness) for storage efficiency

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Ease of operation

If modular pot uses slide-locking connections for easy assembly and disassembly, then ease of operation is improved, but device complexity increases due to multiple partitions and interfaces

Engineering Contradiction:
Improveease of assemblyVSAvoidnumber of components
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

Multiple functional features are merged into each partition element: the planar structure provides both the bowl surface and the mounting interface, the interlocking edges serve as both structural connectors and alignment guides, and the geometry of each partition incorporates features for both assembly and disassembly. This merging reduces the number of separate components needed while maintaining ease of operation

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

Each partition is designed as a universal component that can function in multiple positions and orientations within the assembly. The same basic partition design with standardized interlocking interfaces can be arranged to form different configurations, and each partition serves both as a structural element and as a connector to other partitions, reducing the need for specialized components

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

The underlying invention in particular is directed to a modular pot (1, 2) comprising at least three partitions (1a, 1b, 1c) inter-connectable with each other by slide-locking connections, wherein the partitions (1a, 1b, 1c) are planar in shape and have substantially the same basic shape, each partition (1a, 1b, 1c) comprising a slide-locking male interface having one or more male hook-laps, and a slide-locking female interface having one or more counterpart female locking slots for locking hook-laps therein in a slide-to-lock movement, wherein with each partition (1a, 1b, 1c), the one or more hook-laps of the male interface arranged along a respective first locking axis, and the one or more slots of each female interface arranged along a respective second locking axis, such that the first and second locking axis of each partition (1a, 1b, 1c) have one common point of intersection, and wherein hook-openings of the hook-laps of the male interface of one of the partitions (1c) are oriented towards the associated point of intersection, whereas hook-openings of the hook-laps of the male interface of the other partitions (1a, 1b) are oriented away from their associated point of intersection.
