Solution Overview
Problem
Buildings requiring high air exchange rates due to noxious substances, such as hazardous chemicals, face significant energy losses and increased costs, while on-board display screens in working devices add to their expense.
Innovation Solution
A novel air treatment device that reduces air exchange rates by purging noxious substances using a circulation fan and filter system, and a handheld unit with scanning, networking, and input capabilities to control working devices without the need for on-board displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If high air exchange rates are used to remove noxious substances, then air quality and safety are improved, but energy loss increases
Solution Approach 1:
The patent extracts and removes noxious substances from the air stream using filtration systems and chemical treatment devices, allowing the air to be recirculated rather than requiring continuous high-rate air exchanges with outdoor air, thus reducing energy loss while maintaining air quality
Solution Approach 2:
The system recovers clean air after noxious substances are removed through filtration and chemical treatment, recirculating it back into the space rather than discarding it through continuous air exchange, thereby reducing the energy required for heating or cooling outdoor air
2Ease of operation
If on-board display screens are installed in working devices, then user interface capability is improved, but device cost increases
Solution Approach 1:
The patent employs universal remote control devices (smartphones, tablets, laptops) that users already possess to control multiple working devices, eliminating the need for each device to have its own on-board display screen and reducing overall system cost while maintaining user interface capability
Solution Approach 2:
The system introduces a wireless communication intermediary (WiFi network and mobile device) that mediates between the user and the working device, allowing control and monitoring without requiring expensive on-board displays in each device
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

AI summary
Apparatus for transforming the air exchange load of a higher air exchange rate space into the air exchange load of a lower air exchange rate space, the apparatus including: a housing for mounting to a surface of the higher air exchange rate space; an air inlet formed in the housing; at least one air outlet formed in the housing; a passageway extending through the housing and connecting the air inlet to the at least one air outlet; a circulation fan disposed in the passageway so as to draw the air of the higher air exchange rate space into the air inlet, through the passageway, and return that air to the higher air exchange rate space through the at least one air outlet; and a filter disposed in the passageway for purging noxious substances from the air passing through the passageway.
