Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High energy costs associated with increased air exchanges in laboratory and other building spaces due to the presence of noxious substances, and the added expense of on-board display screens in control devices.
Innovation Solution
A novel air treatment device that reduces the air exchange rate from 8-12 exchanges per hour to 2-4 exchanges per hour by purging noxious substances using a filter, and a QR code-based system for controlling devices without the need for on-board display screens, utilizing a handheld unit with scanning, networking, and input capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the air exchange rate is increased to ensure air quality in laboratory spaces with noxious substances, then the safety and comfort of occupants is improved, but the energy cost increases significantly
Solution Approach 1:
The invention extracts and removes noxious substances from the air using a filter system, allowing the air to be recycled rather than exchanged. This eliminates the need for high-rate air exchanges while maintaining air quality safety.
Solution Approach 2:
The system recycles air that has been filtered of noxious substances, recovering usable air that would otherwise be discarded through air exchanges. This recycling process significantly reduces energy consumption associated with heating or cooling fresh air.
2Ease of operation
If an on-board display screen is added to the control device, then the ease of operation is improved, but the manufacturing cost increases
Solution Approach 1:
The control device is designed to work with various types of display interfaces (on-board screens, handheld units, remote devices) without requiring device-specific hardware modifications. This universal interface approach allows manufacturers to omit expensive on-board displays while maintaining full operational capability through alternative interfaces.
