Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automated test equipment for semiconductor devices lacks flexibility and efficiency in handling parameters, data management, and maintenance planning, particularly for spare parts like contactor sockets, which are critical for effective test procedures and equipment longevity.
Innovation Solution
Incorporation of an electronic component in spare parts like contactor sockets for data storage and processing, combined with an operator terminal and data exchange interfaces, allows for real-time data monitoring, maintenance planning, and control units to enhance data management and predictive maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data storage and processing capabilities are added to spare parts, then data management and predictive maintenance are improved, but device complexity increases
Solution Approach 1:
The electronic component serves multiple functions: storing data about the spare part's condition, processing sensor data, and communicating with both the operator terminal and maintenance planning system. This multi-functionality allows a single addition to the spare part to address multiple maintenance and monitoring needs simultaneously.
Solution Approach 2:
The electronic component acts as an intermediary between the spare part's physical state (monitored by sensors) and the external monitoring systems (operator terminal and maintenance planning system). It collects, processes, and transmits data, bridging the gap between the spare part and the maintenance management infrastructure.
2Productivity
If real-time data monitoring is implemented, then equipment performance and yield are improved, but data management complexity increases
Solution Approach 1:
The system continuously monitors spare part data through sensors and the electronic component, providing real-time feedback to the maintenance planning system. This feedback loop enables proactive maintenance decisions based on actual spare part condition, improving equipment yield through timely interventions.
Solution Approach 2:
The electronic component within the spare part autonomously collects and processes data from integrated sensors, performing self-monitoring without requiring external intervention. This self-service capability reduces the burden on external data management systems while maintaining comprehensive monitoring.
3Ease of operation
If electronic components are integrated into spare parts, then data exchange and maintenance planning are improved, but ease of manufacture decreases
Solution Approach 1:
The electronic component is integrated directly into the spare part structure, merging the data storage and processing functionality with the mechanical component. This integration eliminates the need for separate external electronics and reduces the number of assembly steps, despite the added complexity of the electronic element itself.
