Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for testing human olfactory systems lack standardization, making it difficult to accurately assess olfactory function and predict cognitive impairment or health conditions, as they do not provide standardized odorants or automated systems for quantitative analysis.
Innovation Solution
A system with automated, standardized odor-delivery cartridges and a database for quantitative comparison, allowing for precise measurement and calibration of odorant concentrations, and real-time analysis of olfactory performance against a demographic database to generate an Olfaxis Index.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual odor delivery methods are used, then device complexity is reduced, but measurement precision and reliability of olfactory testing deteriorate
Solution Approach 1:
The patent replaces manual mechanical odor delivery with an automated digital olfactometer system that uses computer-controlled pneumatic delivery. The system substitutes human-operated mechanical methods with automated electronic control, achieving precise odorant concentration delivery through digital control of gas flow and mixing ratios, thereby improving measurement precision while accepting increased device complexity.
Solution Approach 2:
The system incorporates automated calibration and quality control features that allow the olfactometer to self-regulate and self-verify its performance. The automated system performs self-checks and adjustments, reducing the need for manual intervention and maintaining consistent precision without requiring complex manual操作流程.
2Reliability
If standardized odorant delivery systems are implemented, then reliability of olfactory assessment improves, but device complexity increases
Solution Approach 1:
The digital olfactometer is designed as a universal platform that can deliver multiple different odorants through a single integrated system. The device incorporates interchangeable odorant reservoirs and a common delivery mechanism that handles various odorant types, achieving standardized reliable delivery across different substances without requiring separate complex systems for each odorant.
Solution Approach 2:
The system achieves reliability through precise control and standardization of key parameters including odorant concentration, delivery timing, flow rate, and mixing ratios. By establishing standardized parameter ranges and control protocols, the system ensures consistent and reliable olfactory assessment across different testing conditions while managing complexity through parameter-based standardization rather than structural complexity.
3Productivity
If quantitative automated analysis is used, then productivity of diagnostic process improves, but device complexity increases
Solution Approach 1:
The system incorporates automated data collection, processing, and interpretation with feedback loops that provide real-time results. The digital olfactometer automatically records patient responses, compares them against normative data, and generates diagnostic interpretations, improving productivity through automated feedback mechanisms while managing complexity through software-based rather than hardware-based feedback systems.
Solution Approach 2:
The system uses software and database systems as intermediaries between the physical odor delivery apparatus and the diagnostic interpretation. The intermediary layer handles complex data processing, statistical analysis, and result interpretation, allowing the physical hardware to remain relatively simple while achieving high productivity through sophisticated software mediation.
