Solution Overview

Problem

Temperature control modules for food tempering machines are complex and difficult to clean, with detachable parts that can lead to contamination and slow cleaning processes, posing hygiene risks during food processing.

Innovation Solution

A temperature control module with a permanently connected inner and outer tube assembly that eliminates detachable joints, allowing for easy cleaning and preventing contamination by ensuring all food contact is with the inner tube surface, and featuring separate temperature control channels for efficient temperature control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If detachable joints and multiple individual parts are used in the temperature control module, then the structure allows for assembly and disassembly, but cleaning time increases and contamination risk increases

Engineering Contradiction:
ImproveAssembly and disassembly capabilityVSAvoidCleaning time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent merges the inner tube and outer tube into a permanently connected one-piece assembly, eliminating detachable joints between these components. This integration allows the temperature control module to be cleaned as a single unit without disassembly, directly resolving the contradiction by combining parts that would otherwise require separate handling and cleaning.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent segments the temperature control module into distinct functional zones: a food-contact zone (inner tube interior) and a non-food-contact zone (outer tube and connection flanges). This segmentation allows the food-contact surface to be cleaned independently and quickly, while the non-food-contact parts remain permanently attached but do not require the same level of cleaning, thus reducing overall cleaning time.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If detachable joints and connection flanges with tie rods are used, then the structure allows for assembly and disassembly, but joint gaps accumulate contaminants and hygiene is compromised

Engineering Contradiction:
ImproveAssembly and disassembly capabilityVSAvoidContamination risk
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent merges the inner tube and outer tube into a permanently connected assembly, eliminating the joint gaps that exist between detachable components. By permanently connecting these tubes, the design removes the crevices and gaps where contaminants could accumulate, directly addressing the hygiene problem while maintaining structural integrity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent extracts the tie rods and nuts from the design, replacing them with a permanently connected tube structure. This extraction eliminates the additional joints and connection points that would create contamination risks, simplifying the structure and improving hygiene by removing potential contaminant accumulation zones.

Inventive Principle:
Principle #2Taking out (Extraction)

3Strength

If multiple individual parts with nuts and tie rods are used, then the structure provides mechanical connection, but the number of parts increases and cleaning complexity increases

Engineering Contradiction:
ImproveMechanical connection strengthVSAvoidNumber of individual parts
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The patent merges multiple individual parts (inner tube, outer tube, connection flanges, tie rods, nuts) into a permanently connected assembly. This consolidation maintains the mechanical strength needed for the temperature control module while dramatically reducing the number of separate components, thereby simplifying the device and reducing cleaning complexity.

Inventive Principle:
Principle #5Merging (Combining)

4Adaptability or versatility

If detachable components are used for mass change, then different food masses can be processed, but cleaning and reassembly time increases

Engineering Contradiction:
ImproveAbility to change food massVSAvoidCleaning and reassembly time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent segments the cleaning requirement into two parts: the food-contact inner tube surface that requires cleaning for mass changes, and the permanently attached outer tube and connection components that do not require cleaning. This segmentation allows for rapid cleaning of only the necessary surface, maintaining adaptability for different food masses while minimizing the time loss associated with cleaning and reassembly.

Inventive Principle:
Principle #1Segmentation
