Solution Overview

Problem

The existing nanoparticle synthesis apparatus using electron beams faces challenges in preventing radiation leakage from the shielding chamber and facilitating maintenance and repair due to the installation of wirings and pipes, which complicates the synthesis process.

Innovation Solution

The apparatus incorporates a radiation shielding chamber with a partition wall, a cable bracket that covers openings with lead or metal materials, and a movable reactor, allowing for the prevention of radiation leakage and enabling easier maintenance by forming the high-voltage cable and cooler pipe in a zigzag pattern and using shielding bars to block radiation, along with auxiliary brackets to cover auxiliary holes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If wirings and pipes are press-fitted into the radiation shielding chamber in an interference-fit manner, then the shielding structure is simplified, but it becomes difficult to maintain and repair the wirings or pipes

Engineering Contradiction:

Improveshielding structureVSAvoidmaintenance and repair of wirings and pipes

Core Design Contradiction:

Device complexityVSEase of repair

Solution Approach 1:

The opening in the radiation shielding chamber is divided into multiple sections (first opening and second opening) with corresponding cable brackets positioned at different locations. This segmentation allows individual components to be accessed and replaced independently without requiring complete disassembly of the shielding structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The cable bracket is designed with movable and adjustable characteristics, allowing it to be repositioned or removed to facilitate maintenance of wirings and pipes. The dynamic design enables the shielding system to adapt during maintenance operations while maintaining radiation protection during normal operation.

Inventive Principle:

Principle #15Dynamics

2Productivity

If wirings and pipes penetrate the radiation shielding chamber, then the nanoparticle synthesis process can be supported, but radiation may leak from the penetration points

Engineering Contradiction:

Improvenanoparticle synthesis capabilityVSAvoidradiation leakage

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

Cable brackets made of radiation-shielding material are positioned at the opening to serve as intermediary structures. These brackets provide dedicated pathways for wirings and pipes to pass through while maintaining radiation shielding, thus preventing radiation leakage while supporting the nanoparticle synthesis process.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

Radiation shielding is applied locally at specific penetration points using cable brackets positioned at the opening rather than requiring complete shielding of the entire chamber. This localized approach prevents radiation leakage at critical points while maintaining operational functionality.

Inventive Principle:

Principle #3Local quality

3Object-affected harmful factors

If the opening in the radiation shielding chamber is covered completely, then radiation leakage is prevented, but access for installing and maintaining components becomes difficult

Engineering Contradiction:

Improveradiation leakage preventionVSAvoidaccess for installation and maintenance

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The opening is segmented into multiple sections with corresponding cable brackets positioned at different locations. This allows partial access to different areas of the opening for installation and maintenance operations while maintaining radiation shielding at other sections.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The cable bracket structure is designed to be dynamically adjustable, allowing it to be moved or reconfigured to provide access when needed while maintaining shielding coverage during operation. This dynamic design balances radiation protection with operational accessibility.

Inventive Principle:

Principle #15Dynamics
