Problem

Metal foundries face significant environmental disturbances such as air pollution, heat, noise, CO2 emissions, energy consumption, and waste production, which negatively impact both worker safety and the surrounding environment, and existing technologies do not adequately address these issues while ensuring efficient production.

Innovation Solution

A method and system for operating a metal foundry that involves measuring environmental disturbances and using instructions to control machines, such as adjusting water supply, machine speed, and ventilation, to minimize these disturbances, while also reusing heat for energy efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If traditional foundry operation methods are used, then production efficiency is maintained, but environmental disturbances (air pollution, heat, noise, waste) significantly worsen

Engineering Contradiction:
Improveenvironmental disturbancesVSAvoidproduction efficiency
Core Design Contradiction:
Object-affected harmful factorsVSProductivity

Solution Approach 1:

The system continuously measures environmental disturbances (air quality, noise, heat, energy consumption) and uses this feedback to automatically adjust machine operations. Sensors monitor parameters in real-time and communicate with control systems that modify production processes to minimize environmental impact while maintaining productivity.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The foundry system monitors and adjusts its own environmental performance through integrated sensors and control systems. The system automatically detects environmental disturbances and implements corrective actions without external intervention, such as adjusting ventilation based on air quality measurements or optimizing energy consumption based on real-time monitoring.

Inventive Principle:
Principle #25Self-service

2Object-affected harmful factors

If environmental control measures are implemented, then environmental disturbances are reduced, but system complexity and operational cost increase

Engineering Contradiction:
Improveenvironmental disturbancesVSAvoidsystem complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The system uses multi-functional sensors and control devices that monitor multiple environmental parameters simultaneously. A single integrated control system manages air quality, noise, heat, and energy consumption, reducing the need for separate dedicated systems for each environmental parameter and thereby limiting overall system complexity.

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

Solution Approach 2:

The system automatically monitors and adjusts environmental parameters without requiring complex external management infrastructure. The self-regulating nature of the system reduces operational complexity by eliminating the need for manual environmental monitoring and adjustment procedures.

Inventive Principle:
Principle #25Self-service

3Object-affected harmful factors

If environmental control measures are implemented, then environmental disturbances are reduced, but operational cost increases

Engineering Contradiction:
Improveenvironmental disturbancesVSAvoidenergy consumption
Core Design Contradiction:
Object-affected harmful factorsVSUse of energy by moving object

Solution Approach 1:

The system converts waste heat and other environmental byproducts into useful resources. Heat recovery systems capture waste thermal energy from production processes and reuse it for heating or other purposes, transforming environmental disturbances into beneficial contributions that reduce overall energy consumption and operational costs.

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

Solution Approach 2:

The system recovers and reuses materials and energy that would otherwise be discarded. Spent sand and other waste materials are recovered and processed for reuse in production, reducing the need for virgin materials and associated processing energy. Energy recovery systems capture and reuse thermal energy from exhaust streams and waste heat sources.

Inventive Principle:
Principle #34Discarding and recovering
