Solution Overview

Problem

Existing skewer manufacturing technologies are limited in producing skewers with ingredients of all shapes, including round and square, and do not allow for modifiable combinations of ingredients, often requiring fixed geometric shapes and dimensions, which restricts the versatility of skewer production.

Innovation Solution

A device utilizing a V-shaped mold and counter mold with adjustable horizontal and vertical packing, combined with removable cups and a tamping comb, enables the skewering of ingredients of various shapes and sizes, allowing for multiple combinations and geometric shapes, and can be used manually, semi-automatically, or automatically.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If fixed geometric shapes and dimensions are used for skewers, then manufacturing simplicity is maintained, but versatility in producing skewers with ingredients of all shapes is limited

Engineering Contradiction:
Improveversatility in producing skewers with ingredients of all shapesVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The mold includes adjustable components that can be repositioned to accommodate different ingredient shapes and sizes. The depth-adjustable mechanism allows the same mold to adapt to various product requirements, transforming a static device into a dynamic, versatile tool for producing skewers with ingredients of all shapes.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The mold is designed with multiple cavities and adjustable features that enable it to produce different types of skewers with various ingredient combinations and geometric shapes using a single device, making it a universal tool for diverse skewer production needs.

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

2Adaptability or versatility

If adjustable horizontal and vertical packing is used, then ingredient combinations of various shapes are enabled, but device complexity increases

Engineering Contradiction:
Improvemodifiable combinations of ingredientsVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The mold is divided into multiple independent cavities, each capable of holding different ingredients. This segmentation allows for modifiable combinations of various ingredients while keeping each cavity's function simple and manageable, reducing overall device complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The depth-adjustable mechanism allows vertical positioning of ingredients to be modified, enabling different ingredient combinations and arrangements. This dynamic adjustment capability provides versatility in ingredient combinations without requiring completely separate devices for each configuration.

Inventive Principle:
Principle #15Dynamics

3Manufacturing precision

If tamping is applied to compact ingredients, then skewer density is improved, but ingredient crushing and exudate loss may occur

Engineering Contradiction:
Improveskewer densityVSAvoidingredient crushing and exudate loss
Core Design Contradiction:
Manufacturing precisionVSObject-generated harmful factors

Solution Approach 1:

The mold cavities are designed with specific geometric shapes and dimensions that are optimized for different ingredient types. This local quality optimization ensures that each ingredient is compacted in a way that maintains its structural integrity while achieving the desired skewer density, preventing crushing and exudate loss.

Inventive Principle:
Principle #3Local quality

AI summary

The invention concerns a device for the manual, semi-automatic or automatic production of food kebabs in any shape with any combination of pieces using any skewer or combinations of skewers of any geometric shape. The kebabs are assembled using a V-shaped container or mould (47) and an upside-down V-shaped counter-mould (49). The ingredients are deposited in the V-shaped mould and the upside-down V-shaped counter-mould traps them, forcing them to the desired size by means of a tamping system. The use of cups helps skewer products in a plurality of sizes in various simultaneous combinations. The whole is combined and is skewered onto the skewers previously arranged on preformed support guides allowing any shape of skewer to be received. The tamping system is constituted by: a comb holder (3), a tamping comb (4), a locking and tamping means (7) and an indexing finger (48).
