Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air treatment devices for UV(C) radiation struggle to maintain precise control over process parameters such as UV(C) radiation intensity and air residence time, especially under dynamic conditions, leading to potential deviations from a defined process window, and face challenges with component maintenance, electrical interference, and UV radiation-induced degradation.
Innovation Solution
The device incorporates a fixed lamp holder with positioning means to ensure predictable UV(C) radiation distribution, integrated measuring units for precise parameter measurement, and shielded electrical and signal wires to prevent interference, allowing for reliable operation and easy maintenance within a narrow process window.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed lamp holder with positioning means is used to ensure predictable UV(C) radiation distribution, then manufacturing precision and reliability are improved, but device complexity increases
Solution Approach 1:
The lamp holder includes positioning means that pre-establish the correct spatial relationship between the UV(C) lamp and the treatment chamber before operation. This preliminary positioning action ensures consistent UV(C) radiation distribution without requiring complex adjustment mechanisms during operation, thereby improving reliability while controlling complexity.
Solution Approach 2:
The patent replaces complex mechanical adjustment systems with a fixed lamp holder design that incorporates positioning features directly into the structure. This substitution eliminates the need for complex mechanical systems while maintaining manufacturing precision through integrated positioning elements.
2Reliability
If shielded electrical and signal wires are used to prevent interference, then reliability is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent combines the electrical supply wires and signal wires into a single integrated lamp holder assembly with common shielding. This merging approach maintains electrical interference prevention through unified shielding while simplifying manufacturing and installation compared to separate shielded cable assemblies.
Solution Approach 2:
The lamp holder acts as an intermediary structure that provides shielding for both electrical and signal wires. This intermediary shielding approach prevents electrical interference between the high-voltage supply wires and sensitive signal wires while maintaining ease of manufacture through a single shielding implementation.
3Measurement precision
If integrated measuring units are incorporated for precise parameter measurement, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The measuring units are designed to measure multiple parameters (UV(C) radiation intensity, air flow rate, temperature) using integrated sensors within the lamp holder assembly. This multi-functionality approach improves measurement precision across multiple parameters while controlling overall device complexity through a unified measuring system.
4Ease of repair
If the device is designed for easy maintenance and rapid component replacement, then ease of repair is improved, but manufacturing precision may be compromised
Solution Approach 1:
The lamp holder is designed as a segmented, modular assembly that allows the UV(C) lamp to be quickly removed and replaced without affecting the overall positioning structure. This segmentation enables rapid maintenance while the integrated positioning means ensure manufacturing precision is maintained through the fixed structural relationships.
