Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user manually inserts a predefined circuit (e.g., self-holding, flip-flop) into a ladder diagram using traditional methods, then the circuit can be added to the ladder program, but the operation becomes complex requiring address input and line connection
Solution Approach 1:
The system pre-defines circuit structures (self-holding, flip-flop, interlock circuits) with their connections and addresses already configured. When a user selects a predefined circuit, the system has already prepared the complete circuit template, eliminating the need for users to manually configure addresses and connections during the insertion process.
Solution Approach 2:
The system creates copyable templates of predefined circuits that can be directly inserted into the ladder diagram. Instead of requiring users to build circuits from scratch or manually configure each element, the system provides pre-configured circuit copies that maintain their internal structure and connections, reducing the insertion process to a simple selection and placement operation.
2Productivity
If traditional ladder diagram editing is used with keyboard or mouse, then precise control is achieved, but the editing process becomes time-consuming and complex
Solution Approach 1:
The system pre-configures complete circuit templates with all necessary elements, connections, and addresses before the user needs them. This preliminary preparation allows users to simply select and insert predefined circuits without spending time on repetitive configuration tasks, significantly improving editing efficiency and reducing time loss.
Solution Approach 2:
The system provides a unified interface for both traditional detailed editing and quick predefined circuit insertion. The same ladder diagram editor supports both granular manual editing of individual elements and high-level insertion of complete predefined circuits, allowing users to switch between editing modes based on their needs and optimize their workflow.

AI summary
A ladder display device of the disclosure includes: a ladder circuit storage unit that stores an insertion condition including at least an operation start position of a gesture operation, an operation end position of the gesture operation, and a circuit state of a net on a ladder diagram related to the gesture operation as insertion target ladder circuit information in association with a ladder circuit that is an insertion target; a ladder circuit condition determination unit that, with reference to the ladder circuit storage unit, determines a ladder circuit whose insertion condition is satisfied by a gesture operation performed on the touch panel; a ladder circuit generation unit that generates a ladder circuit determined by the ladder circuit condition determination unit as the gesture operation satisfying an insertion condition; and an edition control unit that inserts a ladder circuit generated by the ladder circuit generation unit into the ladder program.
