Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If constant speed mixers are used to mix emulsified food products, then mixing is achieved through gradual speed options, but mixing time is long and energy consumption is high

Engineering Contradiction:
Improvemixing speedVSAvoidmixing time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent applies dynamics by transitioning from constant speed operation to variable speed operation. The mixer uses chaotic speed variations where the rotation speed continuously changes according to a chaotic function, allowing the system to adapt its mixing action dynamically rather than operating at fixed speeds throughout the mixing process

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements parameter changes by modifying the speed parameter over time using a chaotic function. The rotation speed is no longer constant but varies chaotically within a defined range, creating different shear rates and mixing intensities at different moments, which accelerates emulsion formation and reduces mixing time

Inventive Principle:
Principle #35Parameter changes

2Productivity

If constant speed mixers operate at high speed to reduce mixing time, then productivity increases, but energy consumption increases significantly

Engineering Contradiction:
Improvemixing efficiencyVSAvoidenergy consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent applies periodic action through chaotic variations in rotation speed. Instead of maintaining constant high speed, the mixer operates with periodic speed fluctuations that create chaotic flow patterns. This periodic variation in speed generates turbulence and enhances mixing efficiency without requiring continuously high energy input

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The dynamic speed adjustment allows the system to achieve effective mixing through variable intensity rather than constant high intensity. The chaotic speed profile creates periods of high shear followed by lower shear, optimizing energy utilization while maintaining mixing effectiveness

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If constant speed mixers are used, then operation is simple, but turbulence generation is insufficient for rapid emulsion formation

Engineering Contradiction:
Improveoperation simplicityVSAvoidemulsion formation quality
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The patent changes the speed parameter from constant to chaotically variable, which fundamentally alters the flow regime. This parameter change generates turbulence and chaotic advection that dramatically improves emulsion formation quality, creating more uniform and stable emulsions compared to constant speed operation

Inventive Principle:
Principle #35Parameter changes
