Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If three-dimensional models are generated using range sensors to calculate filling rates, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent creates three-dimensional models (copies) of the storage space and measurement targets using range sensors. Instead of directly measuring complex physical quantities, the system generates simplified digital representations that can be easily processed to calculate filling rates, thereby improving measurement precision while managing system complexity through virtual modeling.
Solution Approach 2:
The patent replaces traditional mechanical measurement methods with optical ranging technology. Range sensors use light or electromagnetic waves to measure distances and generate three-dimensional models, substituting mechanical contact measurement with non-contact optical measurement, which improves precision and reduces physical complexity.
2Measurement precision
If three-dimensional modeling and coordinate system association are performed to calculate filling rates, then measurement precision is improved, but loss of time increases
Solution Approach 1:
The patent establishes a coordinate system and associates it with the storage space model in advance. By pre-defining the reference framework and spatial relationships before actual measurement, the system eliminates the need for complex real-time coordinate transformations during filling rate calculation, thus improving accuracy while reducing processing time.
Solution Approach 2:
The patent divides the measurement process into distinct segments: generating the storage space three-dimensional model, establishing the coordinate system, and then calculating filling rates. This segmentation allows each component to be optimized independently, with the coordinate system serving as a reusable reference that speeds up subsequent measurements.
3Productivity
If multiple storage spaces are measured using three-dimensional modeling, then productivity is improved, but device complexity increases
Solution Approach 1:
The patent creates a universal coordinate system and three-dimensional modeling framework that can be applied to multiple storage spaces. Once the system is established for one storage space, it can be reused and adapted for measuring multiple storage spaces, improving productivity while avoiding the need for separate complex measurement systems for each space.
