Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple microswitches (DIP switches) are used to set control and regulation parameters, then the auxiliary device can be programmed with sufficient accuracy, but the ergonomics and intuitive use of the user interface device deteriorates due to the high number of microswitches, limited dimensions, and difficulty in distinguishing between adjacent switches
Solution Approach 1:
A graphical user interface (GUI) displayed on a screen serves as an intermediary between the user and the auxiliary device programming functions. The GUI presents visual representations of the electrical system with clickable elements that correspond to specific programming functions, eliminating the need for users to manually manipulate multiple microswitches while maintaining precise programming capability.
Solution Approach 2:
The patent replaces the mechanical DIP switch system with an electronic graphical user interface. Instead of physically toggling switches to set parameters, users interact with visual elements on a display through standard input devices (mouse, touchscreen), substituting mechanical interaction with electronic interface interaction while achieving the same programming objectives.
2Ease of operation
If a handheld or laptop computer is used to program the auxiliary device, then programming becomes easier, but practical limitations arise when the switching device is located in awkward positions or when simultaneous programming of multiple devices is required
Solution Approach 1:
The graphical user interface is designed to be universally applicable across multiple auxiliary devices and switching device configurations. The same interface can program different types of auxiliary devices (overcurrent protection, undervoltage protection, etc.) and can be accessed from various locations in the electrical panel, eliminating the need for separate programming tools for different devices.
Solution Approach 2:
The GUI acts as a universal intermediary that can interface with multiple different auxiliary devices through standardized communication protocols. This allows a single interface to program multiple devices sequentially or simultaneously, and to access devices located in various positions within the electrical panel without requiring physical proximity or special positioning.
3Ease of operation
If fixed user interface devices with display are provided on the front side of switching devices, then interaction with the auxiliary device is facilitated, but production complexity and cost increase, and space availability on the front wall is limited
Solution Approach 1:
The graphical user interface is implemented as a universal software-based system that can be integrated into existing switching devices without adding dedicated hardware interfaces to each device. The same GUI software can serve multiple auxiliary devices and can be accessed through standard input devices, eliminating the need for custom-built interface hardware for each switching device model.
Solution Approach 2:
Instead of permanently fixing interface hardware to each switching device, the patent employs a removable or accessible graphical interface that can be added or removed as needed. The interface can be accessed through the electrical panel's existing structure without permanent modifications, allowing manufacturers to produce simpler base devices while offering enhanced interface capabilities when required.
