Solution Overview

Problem

Existing methods for cleaning the internal surface of beam pipes are inefficient, requiring extended exposure to high radiation areas and increasing the risk of missing debris due to difficulty in reaching and seeing within the pipe.

Innovation Solution

A universal vacuum suction head with chamfer slots acting as scoops and 360-degree inlet slits, integrated lighting for illumination, and a wireless camera for user direction and feedback, allowing for effective debris removal from variously shaped piping.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a small tube with a stick or pole is used to retrieve debris, then the vacuuming system can reach into the beam pipe, but the cleaning time exceeds 45 minutes and debris may be missed

Engineering Contradiction:

Improvedebris retrieval capabilityVSAvoidcleaning time

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The suction head is divided into multiple functional zones with multiple inlet slits distributed around its circumference, allowing simultaneous debris intake from multiple locations within the beam pipe cross-section, thereby reducing total cleaning time

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention transitions from a single-point debris retrieval method to a multi-point distributed suction system by arranging inlet slits in multiple dimensions around the suction head, enabling comprehensive debris removal across the entire beam pipe cross-section

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Ease of operation

If a small tube with a stick or pole is used to retrieve debris, then the vacuuming system can operate inside the beam pipe, but exposure to high radiation areas is increased

Engineering Contradiction:

Improvedebris collection capabilityVSAvoidradiation exposure

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The beam pipe cleaning task is segmented into multiple simultaneous suction zones, allowing the technician to complete the job faster and reduce total exposure time to radiation areas

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The suction head is designed with pre-positioned inlet slits and scoops that are ready to capture debris immediately upon insertion, eliminating the need for manual positioning and adjustment during the cleaning process, thereby reducing time spent in radiation areas

Inventive Principle:

Principle #10Preliminary action

3Ease of operation

If a small tube with a stick or pole is used to retrieve debris, then the vacuuming system can remove particulate, but difficulty in seeing within the beam pipe increases the probability of missing debris

Engineering Contradiction:

Improvedebris removal functionVSAvoidvisibility of debris

Core Design Contradiction:

Ease of operationVSDifficulty of detecting and measuring

Solution Approach 1:

LED lights emit visible light that illuminates the beam pipe interior, changing the optical conditions to make debris visible to the technician's eyes, thereby enabling accurate assessment of cleaning completion

Inventive Principle:

Principle #32Color changes

Solution Approach 2:

Lighting is pre-installed on the suction head assembly, so that illumination is automatically provided as soon as the suction head is inserted into the beam pipe, eliminating the need for separate lighting setup and ensuring immediate visibility

Inventive Principle:

Principle #10Preliminary action

4Productivity

If chamfer slots and inlet slits are used for 360-degree suction coverage, then debris removal comprehensiveness is improved, but device complexity increases

Engineering Contradiction:

Improvedebris removal comprehensivenessVSAvoidsuction head structure

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The suction head design with chamfer slots and inlet slits serves multiple functions simultaneously: the chamfer slots act as scoops to push debris toward the center, while the inlet slits capture debris from all directions, creating a multi-functional component that achieves comprehensive cleaning without requiring multiple separate tools

Inventive Principle:

Principle #6Universality (Multi-functionality)
