Mounting Head Operation Data Storage for Failure Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting heads lack detailed operational history storage, making it difficult to identify the cause of failures since the operation history up to the failure point cannot be referenced effectively.
Innovation Solution
A mounting head with a storage section and storage control section that acquires and stores operation data at different timings, allowing for detailed analysis of the operating status and facilitating failure cause identification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If operation time is stored in a memory tag, then maintenance management is facilitated, but detailed operation history cannot be referred to for failure analysis
Solution Approach 1:
The storage memory is divided into multiple storage areas (first storage area, second storage area, third storage area) to segment the operation data into different categories: identification information, operation time, and detailed operation history. This segmentation allows each area to serve its specific purpose while maintaining overall system functionality.
Solution Approach 2:
The patent transitions from storing only a single operation time value to storing detailed operation history data in an additional dimension. The operation history storage area captures multiple parameters (component name, position, operation status, time) to create a comprehensive record that enables failure analysis while maintaining the original operation time tracking functionality.
2Quantity of substance
If only operation time is stored, then storage space is minimized, but failure cause identification becomes difficult
Solution Approach 1:
Different storage areas are assigned different levels of detail based on local requirements. The identification information area stores minimal data (head number), the operation time area stores temporal data, and the operation history area stores detailed operational parameters. This local quality differentiation optimizes storage space utilization while enabling comprehensive failure analysis when needed.
Solution Approach 2:
The system performs preliminary storage of detailed operation history data continuously during operation, so that when a failure occurs, the complete operation history is already available for analysis. This preliminary action eliminates the need for retrospective data collection and enables immediate failure cause identification.
3Reliability
If detailed operation history is stored, then failure analysis capability is improved, but device complexity increases
Solution Approach 1:
The storage memory is divided into multiple storage areas (first storage area, second storage area, third storage area) to segment the operation data into different categories: identification information, operation time, and detailed operation history. This segmentation allows each area to serve its specific purpose while maintaining overall system functionality.
Solution Approach 2:
The control unit acts as an intermediary that manages the complexity of data storage and retrieval. It automatically writes operation data to the appropriate storage areas and reads data for failure analysis, shielding the user from the underlying storage structure complexity while enabling comprehensive failure analysis capabilities.

AI summary
A mounting head is configured to be detachably attached to a mounting device main body. This mounting head includes a storage section having multiple storage areas, and a storage control section configured to acquire multiple operation data relating to an operation of the mounting head individually at different timings and store the multiple operation data individually in the multiple storage areas in such a state that the mounting head is attached to the mounting device main body.
