Solution Overview
Problem
In factories where machining operations are performed, identifying the cause of defective machining due to environmental factors is time-consuming and requires specialized expertise, often leading to delayed detection of health hazards and inefficiencies.
Innovation Solution
A system comprising environmental sensors that measure airflow, temperature, humidity, atmospheric pressure, illuminance, and air pollution, along with a display unit and evaluation unit to visualize and analyze these factors, allowing for precise control of the factory environment and prevention of defective machining.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If environmental monitoring is performed manually by workers, then expertise and experience are required to identify factors, but this limits the number of people who can identify problems and delays detection
Solution Approach 1:
The patent replaces manual environmental monitoring by workers with automated sensor systems. Multiple sensors (temperature, humidity, airflow, dust concentration) automatically collect environmental data, eliminating the need for human expertise in identification while improving measurement precision and enabling broader participation.
Solution Approach 2:
The control unit serves as an intermediary that receives data from multiple sensors, processes the information, and generates alerts when environmental factors cause defective machining. This intermediary system bridges the gap between raw environmental data and actionable insights, replacing the need for human expert analysis.
2Loss of time
If comprehensive environmental monitoring is implemented, then rapid identification of environmental causes is achieved, but system complexity and cost increase
Solution Approach 1:
The system performs preliminary monitoring of environmental factors before defective machining occurs. By continuously measuring temperature, humidity, airflow, and dust concentration, the system detects environmental deviations early, enabling rapid identification of causes before they result in defective products.
Solution Approach 2:
The control unit performs multiple functions: it receives data from various sensor types, processes different environmental parameters, determines whether defective machining is caused by environmental factors, and generates alerts. This multi-functional approach consolidates complexity into a single device rather than requiring separate systems for each function.
3Reliability
If workers rely on their senses to detect environmental changes, then the system is simple, but detection is delayed when workers become accustomed to changes and serious problems are missed
Solution Approach 1:
The sensors continuously monitor environmental factors and provide feedback to the control unit. When environmental parameters deviate from normal ranges or when defective machining is detected alongside environmental anomalies, the system generates alerts. This automated feedback loop ensures reliable detection of environmental changes without relying on worker adaptation or subjective perception.
