Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a correction X-ray detector is dedicatedly designed and manufactured, then the correction function is achieved, but the cost and development time increase
Solution Approach 1:
The patent applies universality by enabling imaging detector elements to serve dual purposes: both imaging and correction functions. The processing circuitry identifies detector elements from the imaging detector that can function as correction detector elements, allowing the same hardware to perform multiple roles and eliminating the need for separate dedicated correction detector manufacturing.
Solution Approach 2:
The patent applies discarding and recovering by identifying and utilizing detector elements that would otherwise be discarded or underutilized in the imaging detector. Elements suitable for correction purposes are recovered from the imaging detector array, transforming potential waste into functional correction components without additional manufacturing cost.
2Reliability
If a correction X-ray detector is dedicatedly designed, then the correction function is achieved, but the development time increases
Solution Approach 1:
The patent eliminates dedicated development time by making the imaging detector universal. The same detector elements and processing circuitry that handle imaging data can identify and process correction data, removing the need for separate development cycles for correction detector design, manufacturing, and integration.
Solution Approach 2:
The patent merges the correction detector functionality into the existing imaging detector system. The processing circuitry combines imaging and correction functions in a single integrated system, eliminating the need for separate development processes and reducing overall development time while maintaining correction reliability.
3Ease of manufacture
If existing detector elements are repurposed for correction, then manufacturing cost decreases, but the selection and identification process becomes complex
Solution Approach 1:
The processing circuitry performs self-service by automatically identifying which imaging detector elements are suitable for correction functions. The system autonomously evaluates detector element characteristics and determines suitability without requiring complex external selection processes, thereby reducing manufacturing complexity while maintaining cost effectiveness.
Solution Approach 2:
The processing circuitry acts as an intermediary that mediates between the imaging detector elements and the correction function requirements. It evaluates element characteristics, determines suitability, and facilitates the repurposing process, simplifying what would otherwise be a complex selection and identification process.
