Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rotor is arranged above the ploughshare to press on the soil structure, then clod breaking effect is improved, but device complexity increases and costly protective hood is required
Solution Approach 1:
The patent extracts the loosening function from the separating device and places it in a receiving device with a loosening tool that acts on the soil before it enters the separating section. This separates the loosening function from the complex rotor mechanism, reducing device complexity while maintaining clod breaking effectiveness.
Solution Approach 2:
The loosening tool performs preliminary loosening action on the soil structure before the soil enters the separating section. This preliminary action breaks up clods in advance, reducing the load on the separating device and eliminating the need for protective hoods.
2Manufacturing precision
If additional processing steps are used for heavy soil, then separation quality is improved, but productivity decreases and setup times increase
Solution Approach 1:
The loosening tool performs preliminary loosening of heavy soil structures before separation, breaking up clods and improving soil structure in advance. This eliminates the need for additional processing steps during separation, maintaining high separation quality while increasing productivity and reducing setup times.
Solution Approach 2:
The loosening tool is designed with adjustable star bodies and variable gap settings that can be dynamically adapted to different soil structures, including heavy soils. This dynamic adjustability allows the machine to handle various soil types efficiently without requiring multiple processing steps.
3Device complexity
If screen gaps are made fixed, then device complexity is reduced, but adaptability to different soil structures decreases
Solution Approach 1:
The separating device incorporates adjustable screen gaps that can be varied according to different soil structures and working conditions. This dynamic adjustability allows the machine to adapt to various soil types while maintaining manageable device complexity through systematic adjustment mechanisms.
4Manufacturing precision
If working speed is reduced to improve separation quality, then separation precision is improved, but productivity decreases
Solution Approach 1:
The loosening tool performs preliminary loosening of the soil structure before separation, breaking up clods and creating a more uniform soil flow. This preliminary action allows the separating device to operate at higher speeds while maintaining high separation precision, thus increasing productivity without sacrificing quality.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The machine increases productivity and reduces setup and repair times by breaking up clods and mixing soil layers, improving processing quality and throughput, especially on heavy and wet soils, while maintaining constant power consumption and unaffected working speed.
Implementation Method 1
a loosening phase in the area before the separating section of the separating device... Through a more aggressive picking up of heavy arable soil with simultaneous loosening, broken soil parts are produced
Implementation Method 2
a separating device that detects the field soil... processed here by means of the respective separating rollers or similar sorting assemblies... sorted solids are separated next to the dam floor
