Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an electrical interface with exposed electric wire connector is used for power supply, then the excrement collector can receive electric energy, but the electrical interface is easy to rust and the connection is unstable
Solution Approach 1:
The patent replaces the traditional mechanical electrical connector (exposed electric wire butt joint) with a wireless electromagnetic induction power transmission system. The main unit includes a first coil unit that generates a magnetic field, and the excrement collector includes a second coil unit that receives this magnetic field to induce current for power supply. This substitution eliminates the need for exposed electrical connectors, thereby preventing rust and improving connection stability.
Solution Approach 2:
The patent introduces a magnetic field as an intermediary medium for power transmission between the main unit and the excrement collector. The first coil unit in the main unit generates a magnetic field that penetrates through the air gap to the second coil unit in the excrement collector, enabling wireless power transfer without direct electrical contact. This intermediary approach avoids the rust and instability issues of direct electrical connectors.
2Ease of operation
If a traditional connecting apparatus with electric wire is used, then power supply is achieved, but the connection process is inconvenient and time-consuming
Solution Approach 1:
The patent replaces the manual connection process of plugging and unplugging electrical connectors with a wireless electromagnetic coupling system. The user simply needs to bring the excrement collector near the main unit for the coil units to automatically establish magnetic coupling for power transfer. This eliminates the time-consuming and inconvenient process of handling exposed electrical connectors.
Solution Approach 2:
The wireless electromagnetic induction system enables automatic power connection without requiring manual intervention to connect electrical interfaces. When the excrement collector is positioned near the main unit, the magnetic field automatically induces current in the second coil unit, providing self-service power supply that reduces user effort and connection time.
3Device complexity
If exposed electrical interfaces are used for power supply, then the excrement collector can be powered, but the design becomes more complex and larger
Solution Approach 1:
The patent replaces the complex mechanical assembly of exposed electrical connectors, wiring harnesses, and associated protective structures with a compact wireless electromagnetic induction system. The coil units require minimal structural support and can be integrated directly into the excrement collector housing, significantly reducing overall design complexity and device volume.
Solution Approach 2:
The patent merges the power supply function with the structural housing of the excrement collector by integrating the second coil unit directly into the collector body. This eliminates the need for separate electrical interface assemblies and reduces the overall device volume while simplifying the connection structure.
