Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional maturation processes are used, then sensory characteristics such as tenderness and aroma are achieved, but the process requires long periods of time leading to increased energy consumption and costs

Engineering Contradiction:
Improvesensory characteristicsVSAvoidmaturation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-cultivating Aspergillus fungi on chestnut substrate to produce proteases before adding them to the meat. This preparation in advance allows the maturation process to proceed faster when the enzymes are applied, reducing the overall maturation time while still achieving the desired sensory characteristics.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent uses proteases produced by Aspergillus fungi as an intermediary substance to mediate the maturation process. These enzymes act as catalysts that accelerate the breakdown of muscle tissue and connective tissue, enabling the achievement of tenderness and aroma characteristics without requiring long maturation periods.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If nitrates or nitrites are added to preserve matured foods, then food safety is improved, but toxic effects and health risks such as increased cancer risk occur

Engineering Contradiction:
Improvefood safetyVSAvoidtoxic effects
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies the taking out principle by removing harmful nitrate and nitrite preservatives from the maturation and preservation process. Instead, it uses natural proteases from Aspergillus fungi that achieve preservation through enzymatic action and pH control, eliminating the toxic effects associated with chemical preservatives while maintaining food safety.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent converts the naturally acidic environment of meat (pH 5.5-5.6) from a potential risk factor that promotes microbial growth into a beneficial tool for preservation. By utilizing the meat's own acidity combined with enzymatic action from Aspergillus proteases, the process achieves preservation without requiring toxic chemical additives.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

3Reliability

If maturation processes are extended to improve sensory characteristics, then tenderness and aroma are enhanced, but energy consumption and storage requirements increase

Engineering Contradiction:
Improveorganoleptic characteristicsVSAvoidenergy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent applies parameter changes by modifying the biochemical environment through the addition of proteases, which change the rate parameters of tissue breakdown. This enzymatic catalysis accelerates the maturation reactions, allowing the same organoleptic characteristics to be achieved in shorter time frames with reduced energy input and storage requirements.

Inventive Principle:
Principle #35Parameter changes
