Solution Overview

Problem

Conventional tracking systems for high energy particles fail to separate the wide range of high energy particles' kinetic energy spectrum, require high voltage supply, and necessitate periodic maintenance, while existing systems like Atmospheric ray tomography and muon trackers do not effectively address these issues.

Innovation Solution

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If conventional tracking systems are used to determine particle paths and measure energy, then particle tracking capability is achieved, but the system cannot separate the wide range of high energy particles' kinetic energy spectrum

Engineering Contradiction:
Improvekinetic energy spectrum separationVSAvoidenergy range coverage
Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The detector is divided into multiple detector units, each with specific fibre arrangements to detect particles in different energy ranges. The hodoscope comprises multiple such units stacked together, allowing segmentation of the wide energy spectrum into detectable segments through the tracking chambers

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a new dimensional approach by using multi-layer fibre arrangements (first fibres in grooves of first panel, second fibres in grooves of second panel) at angles to each other, creating a three-dimensional detection capability that enables kinetic energy spectrum separation beyond conventional two-dimensional tracking

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Reliability

If conventional tracking systems are deployed for effective operation, then particle detection capability is maintained, but high voltage supply and periodic maintenance are required

Engineering Contradiction:
Improveoperational continuityVSAvoidhigh voltage supply requirement
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces conventional high-voltage-based detection mechanisms with a mechanical/optical fibre-based detection system. The scintillating fibres coupled with photodetectors provide a lower-voltage alternative that maintains detection reliability while eliminating complex high voltage supply requirements

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The detector units are designed with modular fibre-optic components that are simpler and potentially replaceable, reducing maintenance complexity compared to conventional high-voltage systems. The modular design allows individual units to be replaced without affecting the entire system

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Measurement precision

If stacked panels with fibres are used for particle tracking, then tracking accuracy is improved, but device weight increases

Engineering Contradiction:
Improvetracking accuracyVSAvoiddetector unit weight
Core Design Contradiction:
Measurement precisionVSWeight of stationary object

Solution Approach 1:

The patent uses thin fibre-optic layers and panel structures instead of bulky conventional detector materials. The fibres are arranged in thin grooves on panels, creating a lightweight yet precise tracking system that maintains high measurement precision without excessive weight

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The detector combines different materials (panel materials, fibre materials, support member materials) to create a lightweight composite structure. The support members use materials with appropriate strength-to-weight ratios, and the overall design integrates multiple materials to achieve both precision and weight reduction

Inventive Principle:
Principle #40Composite materials

4Strength

If conventional support structures are used in detector panels, then structural strength is maintained, but inherent scattering from construction materials increases

Engineering Contradiction:
Improvepanel structural strengthVSAvoidparticle scattering
Core Design Contradiction:
StrengthVSObject-generated harmful factors

Solution Approach 1:

The support members are designed with honeycomb or foam structures, which are porous materials that provide structural strength while minimizing material density. This reduces the amount of material particles must traverse, thereby reducing inherent scattering while maintaining the mechanical strength needed to support the detector panels

Inventive Principle:
Principle #31Porous materials
