Solution Overview

Problem

Existing imaging systems for inaccessible or uninhabitable areas, such as storm and sewer pipes, face challenges with invasive setups, limited maneuverability, and inefficient power consumption due to non-coincident light and imaging axes, necessitating a more convenient and efficient long-range imaging solution.

Innovation Solution

An imaging system with coincident light and imaging axes using parabolic reflectors and a high-zoom imaging device, integrated into a single housing, which reduces power consumption and enhances maneuverability by eliminating the need for external power cables.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If invasive inspection devices like pipe crawlers are used, then detailed images can be obtained, but the setup is inconvenient and time-consuming

Engineering Contradiction:
Improveimage detail qualityVSAvoidsetup and operation time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent replaces the mechanical pipe crawler system with a stationary imaging head that uses optical zoom and focused illumination to achieve detailed imaging without physical movement through the pipe, eliminating the time-consuming setup and operation of invasive devices

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

Solution Approach 2:

The patent introduces a stationary imaging head positioned at an intermediate location (manhole or access point) that uses optical systems and controlled illumination to capture detailed images of pipe interiors without requiring the device to travel through the entire pipe length

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If invasive inspection devices are used, then detailed imaging is possible, but the device complexity and maneuverability are limited

Engineering Contradiction:
Improveimage detail qualityVSAvoiddevice configuration complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical navigation systems with a stationary imaging head that uses optical zoom capabilities and controlled illumination to achieve detailed imaging, significantly reducing device complexity and eliminating maneuverability constraints

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

Solution Approach 2:

The imaging head is designed to be universally applicable to various pipe configurations by using optical zoom and adjustable illumination rather than requiring mechanical adaptation to different pipe sizes and shapes

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Area of stationary object

If light beam is not focused and axes are not coincident, then illumination covers wider area, but power consumption increases

Engineering Contradiction:
Improveillumination areaVSAvoidpower consumption
Core Design Contradiction:
Area of stationary objectVSUse of energy by moving object

Solution Approach 1:

The patent applies focused illumination that concentrates light energy along the optical axis to achieve efficient long-range imaging, using parabolic reflectors to direct light precisely where needed rather than dispersing it broadly, thereby reducing power consumption while maintaining effective illumination area

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent uses parabolic reflectors with specific curvature to focus and direct light beams efficiently along the optical axis, achieving concentrated illumination that reduces power requirements compared to non-focused lighting arrangements

Inventive Principle:
Principle #14Spheroidality (Curvature)
