Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If seeds are irradiated with laser beams using a divergent beam, then the coverage area is increased, but the energy dose precision is reduced
Solution Approach 1:
The patent divides the seed treatment process into discrete segments by placing individual seeds in separate recesses on the rotating disk. Each seed receives a focused, non-divergent laser beam independently, ensuring precise energy dosing while treating multiple seeds simultaneously. This segmentation allows concentrated energy delivery to each seed without the energy dispersion that occurs with divergent beams covering large areas.
Solution Approach 2:
The invention implements local quality by providing each seed with a tailored, focused laser irradiation experience. The recesses on the rotating disk create localized treatment zones where laser energy is concentrated precisely on individual seeds. This local quality approach ensures that each seed receives the optimal energy dose without being affected by the energy dispersion inherent in divergent beam systems that treat large areas.
2Stability of the object's composition
If seeds are moved along a vibrating sloping plane for irradiation, then the seed distribution is improved, but the irradiation efficiency is reduced
Solution Approach 1:
The patent replaces the mechanical vibrating sloping plane system with a rotating disk mechanism that uses centrifugal force and controlled rotation to achieve both uniform seed distribution and efficient irradiation. Seeds are placed in recesses on the rotating disk, which delivers them through the laser beam path in a controlled manner. This substitution eliminates the time-consuming vibration and sloping plane transit while maintaining uniform distribution and adding precise rotational control for efficient treatment.
Solution Approach 2:
The invention applies preliminary action by pre-positioning seeds in recesses on the rotating disk before irradiation begins. This pre-arrangement ensures uniform seed distribution is achieved through the rotational mechanics of the disk rather than requiring time-consuming vibration during the treatment process. The seeds are already in their treatment positions, ready for immediate and efficient laser irradiation as the disk rotates them through the beam path.
3Device complexity
If a common housing integrates seed displacement assembly and lasers, then the device complexity is reduced, but the treatment precision may be compromised
Solution Approach 1:
The patent merges the seed displacement assembly and laser irradiation system into a single integrated device housed in a common housing. The rotating disk with seed-receiving recesses is positioned within the housing to rotate through the laser beam path. This merging reduces overall device complexity by combining seed handling and treatment functions in one unit while maintaining precision through careful design of the recess positions and laser focal points.
Solution Approach 2:
The invention creates equipotentiality by designing the rotating disk system so that all seeds in the recesses are at equivalent positions relative to the laser beam path during rotation. This ensures that each seed receives the same level of irradiation precision regardless of its position on the disk, maintaining treatment precision while allowing the benefits of integrated housing design. The geometric arrangement ensures uniform treatment conditions for all seeds.
