Solution Overview

Problem

Conventional tempering machines have difficulty accessing the duct and conveyor element for effective washing, requiring lengthy disassembly processes that are inefficient in an industrial context.

Innovation Solution

A tempering machine design that includes a pivoting plate to open the bottom end of the duct, allowing easy removal and extraction of the conveyor element, along with a mechanism for introducing and evacuating cleaning liquid for thorough cleaning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the duct and conveyor element are designed to be enclosed and integrated within the tempering machine, then the machine structure is compact and complete, but accessibility for washing and maintenance is difficult requiring lengthy disassembly

Engineering Contradiction:
Improveaccessibility for washingVSAvoiddisassembly operations
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The duct is divided into an upper fixed portion and a lower removable portion that can be separated from each other. The conveyor element is also segmented into sections that can be independently removed. This segmentation allows the conveyor element to be accessed and removed without disassembling the entire machine structure, resolving the contradiction between compact integrated design and ease of maintenance access.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The conveyor element is extracted from the enclosed duct structure through removable access points. The lower portion of the duct can be taken out to facilitate complete removal of the conveyor element for washing. This extraction principle allows maintenance access without requiring complex disassembly of the entire machine, improving ease of operation while maintaining structural integrity during normal operation.

Inventive Principle:
Principle #2Taking out (Extraction)

2Productivity

If the conveyor element is firmly mounted within the duct, then the structure is stable and secure, but removal and extraction for cleaning becomes difficult and time-consuming

Engineering Contradiction:
Improvewashing speedVSAvoidconveyor element removal
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The mounting system for the conveyor element transitions from a static fixed connection to a dynamic removable connection. The conveyor element can be securely mounted during operation but easily removed when washing is required. This dynamic mounting system resolves the contradiction by allowing the same structure to serve both stable operation and rapid removal needs.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The duct is designed with pre-positioned removable sections and access points that are prepared in advance for conveyor element removal. These preliminary design features eliminate the need for complex disassembly operations during washing, enabling rapid removal and extraction of the conveyor element without compromising structural stability during normal operation.

Inventive Principle:
Principle #10Preliminary action

3Ease of manufacture

If conventional flushing methods are used for cleaning the duct, then the cleaning process is simple, but optimal cleaning cannot be achieved due to difficult accessibility

Engineering Contradiction:
Improvecleaning simplicityVSAvoidcleaning effectiveness
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The duct is segmented into removable sections that allow direct access to the conveyor element and internal surfaces. This segmentation enables thorough manual cleaning and inspection of areas that would be inaccessible with conventional flushing methods alone, while still maintaining a relatively simple overall cleaning procedure. The structure remains simple but achieves optimal cleaning effectiveness through strategic segmentation.

Inventive Principle:
Principle #1Segmentation
