Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If students conduct experiments on-site, then they can directly operate equipment, but they are limited by time and location
Solution Approach 1:
The patent introduces a remote control system as an intermediary between students and hydraulic experimental equipment. Through network communication and control software, students can operate equipment remotely without physical presence, thus achieving both direct equipment operation and time-location flexibility
Solution Approach 2:
The patent replaces the mechanical system of physical presence and manual operation with an automated remote control system using network communication, control software, and automated control interfaces, enabling students to conduct experiments from any location at any time
2Adaptability or versatility
If virtual simulation is used for remote experiments, then time and location flexibility is improved, but experimental realism and feedback are reduced
Solution Approach 1:
The patent merges virtual simulation with real physical equipment operation. The system combines virtual experimental interfaces with actual hydraulic equipment control, allowing students to interact with real equipment remotely while maintaining the convenience of virtual operation, thus achieving both remote accessibility and experimental realism
Solution Approach 2:
The patent implements real-time feedback mechanisms where students can observe actual experimental results and equipment status remotely. Through network communication and real-time data transmission, students receive immediate feedback from real equipment operations, maintaining experimental authenticity while enabling remote access
3Adaptability or versatility
If remote control system is implemented, then time and location flexibility is improved, but system complexity increases
Solution Approach 1:
The patent implements a universal remote control platform that can control multiple different hydraulic experimental equipment through standardized interfaces. The control system and communication protocols are designed to be equipment-agnostic, allowing one system to serve multiple functions and reducing overall system complexity
Solution Approach 2:
The patent uses parameter-based control where equipment operations are controlled through configurable parameters and settings rather than hard-coded control logic. This allows the system to adapt to different equipment types by changing parameters rather than changing the fundamental control architecture, simplifying the system structure
