Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless data transmission is used with separate energy accumulators (batteries) for each sensor element, then data exchange flexibility is improved, but device complexity and cost increase due to the large number of smaller battery units required
Solution Approach 1:
The patent combines the energy supply function into a single centralized energy accumulator instead of distributing multiple small batteries to each sensor element. This merging approach maintains wireless data transmission flexibility while significantly reducing system complexity and the number of energy storage components required.
Solution Approach 2:
The centralized energy accumulator serves as a universal power source for all sensor elements and data transmission components throughout the agricultural working machine, eliminating the need for individual energy accumulators at each sensing location while maintaining system functionality.
2Device complexity
If a centralized energy source is used for wireless data transmission, then device complexity is reduced, but transmission efficiency deteriorates due to long transmission paths requiring high transmission efficiencies that cannot be easily achieved
Solution Approach 1:
The patent implements local energy conversion by equipping sensor elements with energy converters that transform ambient motion energy into electrical energy locally. This ensures reliable data transmission at each location without requiring high-efficiency long-distance energy transmission from a centralized source.
Solution Approach 2:
The patent introduces energy converters as intermediary devices between the ambient environment and the sensor elements. These converters mediate the energy supply by harvesting motion energy from the agricultural working machine's operation and converting it to electrical energy for local data transmission needs.
3Reliability
If wire-based data transmission is used, then functional reliability is improved, but installation space increases due to wiring networks requiring larger installation space
Solution Approach 1:
The patent replaces the mechanical wiring system with a wireless data transmission system. This substitution eliminates physical cables and connectors, significantly reducing installation space requirements while maintaining data transmission functionality through electromagnetic signal transmission.
4Reliability
If wire-based data transmission with mobile sensors is used, then data exchange reliability is improved, but wear increases due to lines being exposed to great deal of wear when sensor elements are located directly next to movable components
Solution Approach 1:
The patent replaces the mechanical cable connection system with wireless data transmission, eliminating physical wear between moving parts and cable connections. This substitution extends component lifespan by removing the mechanical wear mechanism entirely while maintaining data exchange reliability through wireless communication.
5Reliability
If complex connecting elements with elasticity are used in wire-based systems, then reliability against breakage is improved, but device complexity and cost increase
Solution Approach 1:
The patent eliminates the need for complex elastic connecting elements by replacing the entire mechanical cable-based data transmission system with wireless communication. This substitution removes the complexity of designing and implementing wear-resistant flexible connectors while maintaining reliable data transmission without physical contact.
