Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If multiple production steps with multiple pieces of machinery are used, then confectionery products can be formed, but device complexity and production time increase

Engineering Contradiction:
Improveconfectionery product formationVSAvoidnumber of machinery steps
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent combines multiple separate production operations (mixing, cooking, cooling, crystallization, and extruding) into a single continuous process within one extruder device. The extruder performs all these functions sequentially as the confectionery composition passes through different zones, eliminating the need for multiple separate machines and reducing device complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The extruder is designed as a multi-functional device that can perform mixing, heating, cooling, crystallization, and extruding operations within a single machine. This universal device replaces multiple specialized machines, simplifying the overall production system while maintaining all necessary confectionery formation functions.

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

2Ease of manufacture

If multiple production steps with manual labor are used, then confectionery products can be formed, but labor costs and product variation increase

Engineering Contradiction:
Improveconfectionery product formationVSAvoidmanual labor requirement
Core Design Contradiction:
Ease of manufactureVSExtent of automation

Solution Approach 1:

The patent implements a continuous production process where the confectionery composition flows continuously through the extruder, undergoing all transformations without interruption. This continuous automated process eliminates manual labor between steps and ensures consistent product quality, as the composition passes through standardized zones for mixing, cooking, cooling, and extruding without human intervention.

Inventive Principle:
Principle #20Continuity of useful action

3Manufacturing precision

If lengthy cooling and setting periods are allowed, then confectionery products can be properly formed, but productivity decreases

Engineering Contradiction:
Improveproduct setting qualityVSAvoidproduction speed
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The patent controls the temperature parameters dynamically throughout the extrusion process. The composition is heated to cooking temperature, then cooled to crystallization temperature, and finally extruded at controlled temperatures. These parameter changes are achieved rapidly through the efficient thermal zones within the extruder, maintaining product quality while minimizing processing time.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The necessary cooling and crystallization actions are performed preliminarily within the extruder before the composition exits. The composition is pre-cooled to the required temperature and pre-crystallized within the device, eliminating the need for lengthy post-extrusion cooling and setting periods, thus increasing productivity without compromising quality.

Inventive Principle:
Principle #10Preliminary action

4Manufacturing precision

If additional cooling and mixing steps are added, then confectionery composition can be properly formed, but loss of time and productivity decrease

Engineering Contradiction:
Improvecomposition formation qualityVSAvoidproduction cycle time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent merges cooling and mixing operations into the same continuous process within the extruder. As the composition moves through the device, it undergoes cooling while simultaneously being mixed by the extrusion action, eliminating the need for separate cooling and mixing steps and reducing total production time.

Inventive Principle:
Principle #5Merging (Combining)
