Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If colored labels or tags with symbols are used for line identification, then the user can visually identify and match hydraulic lines correctly, but the labels can detach, degrade, or be discolored by environmental agents, causing loss of identification information
Solution Approach 1:
The patent replaces mechanical/physical identification systems (colored labels, tags, symbols) with an electronic identification system based on RFID technology. Each hydraulic line is equipped with an RFID tag containing a unique identification code, allowing wireless reading and identification without physical labels that can detach or degrade.
Solution Approach 2:
The patent creates a digital copy of the identification information stored in RFID tags, which can be read multiple times without degradation. The identification data is replicated in a database system that can be accessed by multiple machines, ensuring the information persists even if physical components are replaced.
2Adaptability or versatility
If physical identification codes (colors, symbols) are used on hydraulic lines, then the user can match pipes to ports for a specific machine, but the same identification system cannot be used when matching the same implement to a different machine
Solution Approach 1:
The patent implements a universal identification system where RFID tags on hydraulic lines can be read by any machine equipped with the corresponding reader. The centralized database stores identification codes that can be matched across different machine-implement combinations, allowing the same implement to be correctly connected to different machines without changing physical identification markers.
Solution Approach 2:
The patent moves the identification system from a two-dimensional physical space (colored labels on pipes) to a digital information space (RFID tags with unique codes). This allows the identification information to be accessed and interpreted in multiple contexts (different machines) without physical changes, adding a dimensional layer of flexibility to the system.
3Loss of information
If no electronic monitoring system is implemented, then the system is simpler, but there is no information available for predictive maintenance or operational management
Solution Approach 1:
The patent implements a feedback system where RFID readers automatically detect and record connection information when hydraulic lines are connected. This data is stored in a database and can be used to track connection history, monitor system status, and provide information for predictive maintenance without requiring manual input or complex monitoring equipment.
