Mobile Allergen Chamber Standardizing Exposure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fixed allergen exposure facilities face challenges in standardizing allergen levels and exposure conditions, leading to variability in symptom responses across different facilities, which complicates the testing of anti-allergy medications and makes it difficult to compare study findings globally.
Innovation Solution
A mobile allergen test system with a support structure and chamber assembly, including inflatable support members and an environmental control unit, that allows for consistent and controlled airborne allergen exposure across diverse locations, ensuring reproducible results and uniform exposure levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed allergen exposure facilities are used, then allergen exposure can be controlled, but variability in allergen levels and exposure conditions persists across different facilities
Solution Approach 1:
The patent applies parameter changes by standardizing critical exposure parameters including allergen concentration (e.g., 3500±500 pollen grains per cubic meter), temperature (22±2°C), humidity (40±10%), and air exchange rates. These standardized parameters are implemented across all mobile chamber systems regardless of location, ensuring consistent allergen exposure conditions and enabling reliable comparison of clinical trial results across different geographic regions and climates.
2Measurement precision
If fixed facilities are used for drug testing, then allergen exposure is controlled, but the complexity of standardizing across multiple facilities increases
Solution Approach 1:
The patent employs copying by deploying identical mobile chamber systems to multiple locations rather than adapting existing fixed facilities. Each mobile chamber is a replicated unit with standardized construction, environmental control systems, and allergen delivery mechanisms. This copying approach ensures that all facilities operate under the same conditions without requiring complex customization or adaptation of each individual facility, thereby reducing standardization complexity while maintaining measurement precision.
3Adaptability or versatility
If natural allergen levels are used, then patient exposure reflects real-world conditions, but variability in symptom responses increases
Solution Approach 1:
The patent implements feedback mechanisms through continuous monitoring of allergen concentration, temperature, humidity, and air exchange rates within each mobile chamber. Real-time sensors detect deviations from target parameters and trigger automated adjustments to maintain standardized conditions. This feedback control ensures that despite variations in natural allergen sources or environmental conditions at different locations, the actual patient exposure remains consistent, thereby reducing symptom response variability while still using natural allergens.

AI summary
A mobile chamber apparatus includes a support structure of inflatable support members, and a chamber assembly. The inflatable support members may include transverse and upright sections. The chamber assembly may include a top wall, a bottom wall, and one or more side walls. Connectors may detachably couple the support structure and the chamber assembly. Installed, the support structure supports the chamber assembly to enclose an interior space. Inlets may deliver a supply airflow to the interior space, and outlets may deliver a return airflow from the interior space. An environmental control unit may deliver the supply airflow and receive the return airflow. At least one mechanism may be provided for introducing an allergen into the interior space. Human patients may be exposed to the allergen in the interior space, and therefore the mobile chamber apparatus may be used for clinical trials to study allergy response.
