Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a large image section is recorded to cover the entire pallet, then the region of interest is always captured, but unnecessary data is generated increasing bandwidth requirements
Solution Approach 1:
The patent applies dynamics by making the image recording parameters adaptive rather than static. The control unit continuously adjusts the image section, resolution, and other parameters based on real-time detection of the region of interest during the work sequence. This dynamic adaptation allows the system to record only the necessary area at each moment, reducing data volume while ensuring the ROI is always captured.
Solution Approach 2:
The patent implements local quality by applying different recording qualities to different regions. Instead of uniformly recording the entire pallet area at maximum resolution, the system identifies the specific region of interest and applies high recording quality only to that local area, while reducing or eliminating recording in irrelevant areas. This resolves the contradiction by maintaining data quality where needed while minimizing overall data volume.
2Measurement precision
If high-resolution sensors are used to capture detailed image data, then measurement precision is improved, but bandwidth requirements and transmission costs increase
Solution Approach 1:
The system applies different resolution levels to different regions of the image. High-resolution recording is applied only to the detected region of interest where measurement precision is critical, while peripheral or irrelevant areas are recorded at lower resolution or not at all. This local differentiation maintains measurement precision for critical areas while significantly reducing the total data transmission bandwidth required.
Solution Approach 2:
The patent dynamically changes recording parameters including resolution, based on the detected region of interest. The control unit adjusts the resolution parameter adaptively - using high resolution only when and where needed for the ROI, and lowering resolution for other areas. This parameter adaptation resolves the contradiction by optimizing the balance between measurement precision and bandwidth consumption.
3Adaptability or versatility
If static recording parameters are configured for all possible conditions, then the system works under varying conditions, but optimal settings cannot be achieved for specific conditions
Solution Approach 1:
The patent transforms the static recording parameter configuration into a dynamic system. Instead of fixing parameters to work adequately under all conditions, the control unit continuously adapts parameters based on the current detected region of interest and working conditions. This dynamic adaptation allows the system to achieve optimal measurement precision for each specific condition while maintaining versatility across different working scenarios.
Solution Approach 2:
The system implements feedback by using the detection unit to continuously monitor the work sequence and region of interest, then feeding this information back to the control unit which adjusts the recording parameters accordingly. This closed-loop feedback mechanism enables the system to adapt to varying working conditions while maintaining optimal data quality, resolving the contradiction between versatility and precision.
4Loss of information
If all recorded image data is transmitted and processed centrally, then complete data is available for analysis, but latency increases and processing costs rise
Solution Approach 1:
The patent extracts and transmits only the relevant region of interest data to the central processing unit, rather than transmitting all recorded image data. The control unit identifies the ROI and selectively extracts only that portion for transmission. This extraction approach maintains data completeness for the critical analysis areas while significantly reducing transmission time and processing latency, resolving the contradiction between information completeness and time loss.
Solution Approach 2:
The system applies different data processing qualities to different regions. High-quality complete data is transmitted for the region of interest where analysis accuracy is critical, while data from irrelevant areas is either not transmitted or transmitted at lower quality. This local differentiation maintains necessary information completeness for critical areas while reducing overall transmission and processing time.
