Solution Overview

Problem

Current doner kebab slicing machines face issues with inconsistent slicing heights, damage to conical or rough surfaces, complexity in cleaning, and inefficiencies in handling different shapes and sizes, leading to burnt non-sliced areas and mechanical difficulties.

Innovation Solution

An automatic doner kebab slicing machine with a rotisserie and circular knife system, featuring a doner kebab follow-up apparatus that maintains constant position during rotation, minimizes angular motion, and includes a burner that adjusts to the kebab's surface, allowing for precise slicing and easy cleaning, with a mobile arm and tray system for efficient operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If gauge slicing process is used to detect doner kebab meat, then slicing can be performed on cylindrical doner kebabs, but additional displacement is required and non-sliced surfaces will be burnt during second cooking process

Engineering Contradiction:
Improveslicing capabilityVSAvoidslicing height consistency
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The patent replaces the mechanical gauge-based detection system with an optical detection system using sensors that detect the position and surface of doner kebab meat non-contactly, eliminating the need for physical contact and additional displacement operations

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent uses optical sensors to create a digital representation of the doner kebab surface, enabling the system to identify and follow the actual meat surface contour without physical contact, thus achieving precise slicing height control

Inventive Principle:
Principle #26Copying

2Adaptability or versatility

If optic sensors are used to detect doner kebab surface for surface follow-up process, then conical doner kebab can be sliced, but meat pieces hanging out cause rough surface that prevents accurate detection

Engineering Contradiction:
Improvecapability to slice conical doner kebabVSAvoidsurface detection accuracy
Core Design Contradiction:
Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The patent implements a dynamic surface follow-up mechanism where the cutting knife adjusts its position in real-time based on continuous optical detection of the doner kebab surface, enabling adaptation to conical shapes and irregular surfaces while maintaining slicing precision

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent employs a feedback control system where optical sensors continuously monitor the doner kebab surface position and provide real-time signals to adjust the cutting knife depth, ensuring accurate slicing even when surface irregularities occur

Inventive Principle:
Principle #23Feedback

3Adaptability or versatility

If complex apparatus is used to perform doner kebab slicing process, then various shapes and sizes can be handled, but the apparatus becomes difficult to clean

Engineering Contradiction:
Improvehandling capabilityVSAvoidcleaning ease
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent divides the slicing apparatus into modular segments including removable cutting head, detachable sensor units, and separable components that can be easily detached for cleaning, maintaining versatility while simplifying maintenance

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent extracts and separates the cutting mechanism and detection system as independent removable modules from the main body, allowing these components to be easily removed and cleaned without disassembling the entire apparatus

Inventive Principle:
Principle #2Taking out (Extraction)
