Solution Overview

Problem

Existing flake ice production devices face challenges in thoroughly cleaning the tub and evaporator components due to limited access and leakage issues, particularly with limescale deposits and contamination, which compromises hygiene and efficiency.

Innovation Solution

The device features two side parts with a continuous slot allowing the tub part to be easily inserted and removed, forming a liquid-tight trough that surrounds the evaporator roller, enabling thorough cleaning and reliable sealing to prevent liquid escape, with additional features like seals, fastening devices, and a scraper arrangement for enhanced usability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the tub part is firmly connected to the side parts using a clamping device, then the seal between the tub part and side parts is improved, but the ease of detaching the tub part deteriorates

Engineering Contradiction:
Improvesealing reliabilityVSAvoidease of detaching tub part
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The tub is divided into a tub part and side parts that can be separately assembled and disassembled. The tub part can be detached from the side parts for cleaning, while maintaining a reliable seal when assembled. This segmentation allows the tub part to be removed through the continuous slot without requiring complex clamping devices.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The tub part is extracted as a separate removable component from the side parts. It can be completely removed through the continuous slot for thorough cleaning, and then reinserted to form a sealed trough. This extraction eliminates the need for complex fastening mechanisms while maintaining sealing reliability.

Inventive Principle:
Principle #2Taking out (Extraction)

2Ease of operation

If the tub part is made removable for thorough cleaning, then the ease of cleaning is improved, but the risk of liquid leakage deteriorates

Engineering Contradiction:
Improveease of cleaningVSAvoidliquid-tight sealing
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The tub is segmented into a removable tub part and stationary side parts. The tub part can be completely removed through the continuous slot for thorough cleaning, and when reassembled, forms a liquid-tight seal with the side parts, preventing leakage.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A sealing element acts as an intermediary between the tub part and side parts. This sealing element ensures a liquid-tight connection when the tub part is assembled with the side parts, while still allowing the tub part to be removed for cleaning purposes.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Stability of the object's composition

If the tub part rests on the end faces of the side parts with clamping, then the structural stability is improved, but the complexity of assembly and tensioning increases

Engineering Contradiction:
Improvestructural stabilityVSAvoidassembly complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The tub structure is segmented into a tub part and side parts that can be independently positioned. The tub part is inserted through the continuous slot and rests on the end faces of the side parts, providing structural stability without requiring complex clamping or tensioning devices.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The complex clamping and tensioning devices are extracted from the design. Instead, the tub part is simply inserted through the continuous slot and rests on the end faces of the side parts, significantly simplifying the assembly process while maintaining structural stability.

Inventive Principle:
Principle #2Taking out (Extraction)

4Ease of operation

If the outlet for liquid is not at the lowest point of the tub, then the tub can be detached, but the completeness of emptying the tub before removal deteriorates

Engineering Contradiction:
Improveease of detaching tub partVSAvoidliquid remaining in tub
Core Design Contradiction:
Ease of operationVSLoss of substance

Solution Approach 1:

The tub is segmented into a removable tub part and stationary side parts. The tub part can be completely removed through the continuous slot, allowing for complete emptying and thorough cleaning, eliminating liquid residue that would remain if the outlet were not at the lowest point.

Inventive Principle:
Principle #1Segmentation
