Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a separate detector is added to measure muon transit time, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent combines the transit time measurement function with the existing drift tube detector by using the drift tube's inherent timing capability. The drift tube detects both the position and transit time of muons through its drift time measurement mechanism, eliminating the need for separate transit time detectors. This merging of functions reduces device complexity while maintaining measurement precision.
Solution Approach 2:
The drift tube detector is designed to perform multiple functions: it simultaneously measures muon position (through drift radius calculation) and muon transit time (through drift time measurement). This multi-functionality allows the single detector to replace what would traditionally require separate detectors, thereby reducing overall device complexity while preserving measurement capabilities.
2Measurement precision
If complicated calculation methods are used to derive muon tracks from time-zero variable, then measurement precision is improved, but productivity decreases
Solution Approach 1:
The patent pre-calculates and stores the relationship between drift times and muon track parameters in a lookup table during the design phase. During actual operation, the system simply queries this pre-computed table using measured drift times, avoiding complicated real-time calculations. This preliminary action enables fast, real-time muon track detection while maintaining high accuracy through the pre-computed relationships.
3Measurement precision
If drift tube arrays are stacked into multiple layers, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent divides the detector into multiple stacked drift tube layers, with each layer containing parallel drift tubes. This segmentation allows the system to detect muon tracks by measuring drift times in each layer independently and then combining these measurements to reconstruct the full track. The segmentation improves measurement precision through multi-point sampling while keeping each individual drift tube relatively simple in structure.

Function Achieved in This Case
Enables swift and accurate detection of muon tracks in real-time without complicated calculations, simplifying the configuration and improving detection resolution.
Implementation Method 1
When a charged particle, such as a muon, passes through the drift tube, the internally sealed gas is ionized to release electrons.
Implementation Method 2
Anode wire is stretched at the center of each drift tube. When a charged particle, such as a muon, passes through the drift tube, the internally sealed gas is ionized to release electrons. Arrival of the released electrons at the anode wire is detected as transit of a muon.
