Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional processing apparatuses face challenges in operability when registering projected dicing lines and patterns on displayed images, requiring precise numerical input and complex operations.
Innovation Solution
A processing apparatus equipped with a touch panel for image capture and registration, allowing operators to select and register lines on a displayed image by tracing them on the touch panel, with a control unit that detects and registers the lines as key patterns or image capturing routes, enhancing operability and reducing the complexity of the registration process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual entry of numerical values is used for precision processing operations, then measurement precision is maintained, but ease of operation deteriorates
Solution Approach 1:
The patent replaces manual mechanical input operations with an automated image recognition system. The control unit automatically detects lines and patterns in captured images and converts them into processing data, eliminating the need for manual numerical entry while maintaining precision processing capabilities.
Solution Approach 2:
The system enables self-service operation where the processing apparatus automatically captures images, detects relevant lines and patterns, and generates processing data without operator intervention. The control unit autonomously completes the data registration process that previously required manual input.
2Ease of operation
If automated line detection is implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The control unit is designed to perform multiple functions: capturing images, detecting lines and patterns, recognizing patterns, and generating processing data. This multi-functionality consolidates what would otherwise require separate systems into a single integrated control unit, managing complexity through functional integration.
Solution Approach 2:
The patent combines the image capturing unit and control unit into an integrated system where the control unit directly processes captured images. This merging of functions reduces the number of separate components and simplifies the overall system architecture while enabling automated operation.
3Ease of operation
If touch panel with image display is used, then ease of operation is improved, but loss of information increases due to potential tracing inaccuracies
Solution Approach 1:
The control unit displays the captured image on the touch panel and overlays detected lines and patterns for operator verification. This feedback mechanism allows the operator to confirm that the automated detection accurately captured the intended features, preventing information loss through verification and correction if needed.
Solution Approach 2:
The system performs preliminary detection and registration of lines and patterns before final processing. By detecting and storing this information in advance, the system creates a reliable data foundation that can be verified and adjusted before committing to the final processing operation, preventing irreversible information loss.
