Solution Overview

Problem

Conventional methods for detecting objects flying in space, such as space debris or cosmic dust, face challenges in setting up a wide detection area without requiring numerous apparatuses, are limited in size measurement, and need complex calibration, making them cumbersome and time-consuming.

Innovation Solution

A detection apparatus featuring a non-conductive thin film with conductive detection lines arranged in a predetermined array pitch, connected to a detection circuit, which ruptures upon collision, allowing for the detection of objects flying in space without the need for extensive calibration or complex structures, enabling lightweight and flexible deployment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If conventional detection methods (sound/vibration measurement, plasma detection, piezo film voltage measurement, or gas bottle pressure measurement) are used to detect objects flying in space, then detection capability is achieved, but the apparatus complexity and weight increase significantly when expanding the detection area

Engineering Contradiction:
Improvedetection areaVSAvoidapparatus complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The detection area is segmented into multiple independent detection units, each containing a simple detection element (conductive line on insulating substrate). By dividing the large detection area into many small, identical modular units, the system achieves wide coverage while keeping each individual unit simple and lightweight.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent uses identical replicated detection patterns (conductive lines on insulating substrates) across the entire detection area. Instead of using one complex detection apparatus, multiple simple identical detection units are copied and arranged to cover the required area, reducing complexity while maintaining detection capability.

Inventive Principle:
Principle #26Copying

2Area of stationary object

If conventional detection methods are used, then detection capability is achieved, but the weight of the apparatus increases when expanding the detection area

Engineering Contradiction:
Improvedetection areaVSAvoidapparatus weight
Core Design Contradiction:
Area of stationary objectVSWeight of stationary object

Solution Approach 1:

The detection structure uses thin insulating substrates with conductive lines patterned on them, replacing heavy conventional detection apparatus. This thin-film structure provides the necessary detection functionality while minimizing weight, enabling large-area deployment without proportional weight increase.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The detection area is divided into multiple lightweight modular units, each with its own simple detection element. This segmentation allows the system to achieve large total detection area while keeping each component lightweight and the overall structure manageable.

Inventive Principle:
Principle #1Segmentation

3Measurement precision

If conventional detection methods are used, then detection capability is achieved, but calibration time and effort increase significantly

Engineering Contradiction:
Improvedetection accuracyVSAvoidcalibration time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The detection system is designed to be self-calibrating through its inherent binary detection mechanism. The conductive lines on insulating substrates provide natural reference states (intact vs. ruptured), eliminating the need for external calibration equipment or procedures. The system automatically establishes its baseline and detects changes without human intervention.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Instead of calibrating the detection system to recognize objects, the patent inverts the approach by using the absence of conduction (ruptured line) as the detection signal. This inversion simplifies the detection logic to a binary state that requires no calibration, as the intact/ruptured distinction is inherently clear and unambiguous.

Inventive Principle:
Principle #13The other way round (Inversion)

4Area of stationary object

If the detection apparatus is designed for wide detection area, then detection coverage is improved, but the number of required apparatuses increases

Engineering Contradiction:
Improvedetection areaVSAvoidnumber of apparatuses
Core Design Contradiction:
Area of stationary objectVSQuantity of substance

Solution Approach 1:

Multiple detection units are merged into a single integrated detection system. Instead of deploying numerous separate detection apparatuses, the patent combines multiple simple detection elements (conductive lines on insulating substrates) into one unified structure that functions as a single large-area detection system, reducing the number of discrete apparatuses required.

Inventive Principle:
Principle #5Merging (Combining)
