Solution Overview

Problem

Horizontal-axis batch-freezer machines for producing artisan ice cream face challenges in securely holding ice-cream display pans of varying sizes and dimensions, requiring frequent adjustments of locking templates, which complicates operations and makes cleaning difficult.

Innovation Solution

A batch-freezer machine with a shelf featuring a raised side shoulder and a manually-operated locking device that automatically adapts to different pan sizes by using a cam mechanism to push and hold the pan against a concave seat, allowing for secure immobilization without the need for template adjustments, and facilitating easy cleaning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a locking template is used to secure ice-cream pans on the shelf, then the pans are held securely, but the template must be frequently adjusted to match different pan sizes and dimensions

Engineering Contradiction:
Improvesecure holding of pansVSAvoidoperation simplification
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The locking device is designed with a universal locking surface that can accommodate multiple pan sizes and shapes through a single mechanism. The cam mechanism with adjustable locking surface allows one device to perform the function of multiple templates, eliminating the need for frequent template changes while maintaining secure pan holding.

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

2Reliability

If a locking template is used to prevent horizontal movement of pans, then pans are immobilized, but cleaning becomes difficult due to the template's structure

Engineering Contradiction:
Improveimmobilization of pansVSAvoidcleaning ease
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The locking function is extracted from a complex template structure and concentrated into a simple cam mechanism with a locking surface. This simplified structure can be easily removed and cleaned, or integrated into the shelf in a way that allows straightforward cleaning access, eliminating the cleaning difficulties associated with complex templates.

Inventive Principle:
Principle #2Taking out (Extraction)

3Adaptability or versatility

If multiple locking templates are provided for different pan sizes, then all pan sizes can be accommodated, but device complexity increases

Engineering Contradiction:
Improveaccommodation of various pan sizesVSAvoidnumber of templates
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The locking device incorporates a dynamic cam mechanism with an adjustable locking surface that can be positioned at different locations and angles. This dynamic adjustment capability allows a single device to adapt to various pan sizes and shapes, replacing the need for multiple static templates and reducing overall device complexity.

Inventive Principle:
Principle #15Dynamics
