Injection Molding Controller Abnormal Sequence Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of injection molding machines face difficulties in modifying program sequences when abnormalities occur, as analyzing and modifying these sequences is complex and not easily accessible for non-technical users.
Innovation Solution
A controller for injection molding machines that includes a display control unit and an operation sequence creation unit, allowing users to easily input and arrange operation modules on a display screen to create sequences for handling abnormalities, eliminating the need for complex program analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operation sequence is specified by a program created by the manufacturer, then the operation sequence can be precisely controlled, but the user cannot easily modify or determine the sequence when an abnormality occurs
Solution Approach 1:
The patent creates a simplified copy of the operation sequence on the display screen that mirrors the actual program flow. This visual copy allows users to understand and determine the operation sequence without needing to analyze the complex underlying program code, resolving the contradiction between precise control and user accessibility
Solution Approach 2:
The display screen acts as an intermediary between the complex control program and the user. It translates the program's internal logic into a visual representation that users can easily interpret, allowing them to determine operation sequences during abnormalities without directly interacting with or understanding the complex program
2Reliability
If the operation sequence is hardcoded in the control program, then the system maintains stability and reliability, but modification requires complex program analysis that users cannot perform
Solution Approach 1:
The operation sequence is segmented into discrete visual elements on the display screen, each representing a specific operation or decision point. This segmentation allows the system to maintain the integrity of the complete sequence while enabling users to understand and determine individual segments during abnormalities without modifying the underlying program
Solution Approach 2:
The display screen serves multiple functions: it displays normal operation sequences, displays abnormal operation sequences, and provides a visual reference for users to determine appropriate actions. This multi-functionality maintains system reliability while improving user accessibility across different operational states
