Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If a cooling concept is fundamentally changed (e.g., from high pressure to low pressure), then cooling efficiency or energy consumption is improved, but conversion effort and production downtime increase

Engineering Contradiction:
Improveenergy consumptionVSAvoidproduction downtime
Core Design Contradiction:
Loss of energyVSLoss of time

Solution Approach 1:

The cooling device is divided into modular components: a support frame and interchangeable cooling elements. The cooling element can be separated from the support frame, allowing individual replacement without dismantling the entire cooling system. This segmentation enables quick swapping between different cooling element types (e.g., spray bars, shell nozzles) minimizing production downtime during conversion.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The support frame is designed with a universal mounting interface that can accommodate multiple types of cooling elements. The receiving element on the support frame works with adapters on different cooling element designs, allowing a single support frame structure to serve multiple cooling functions and principles without requiring complete system replacement.

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

Solution Approach 1:

The support frame is designed with a universal mounting interface that can accommodate multiple types of cooling elements. The receiving element on the support frame works with adapters on different cooling element designs, allowing a single support frame structure to serve multiple cooling functions and principles without requiring complete system replacement.

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

Solution Approach 2:

An adapter is introduced as an intermediary component between the cooling element and the support frame. This adapter standardizes the connection interface, allowing different cooling element designs to be mounted on the same support frame without increasing overall system complexity. The adapter acts as a mediator that simplifies the interface between diverse cooling elements and the universal support structure.

Inventive Principle:
Principle #24Intermediary (Mediator)
