Device and method for air quantity recording
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ventilation systems lack devices that can provide a specified air quantity to users without requiring them to purchase fans or air conveyor units, and there is a need for a method to record and invoice the air quantity used over time.
Innovation Solution
An air quantity recording and invoicing device comprising an air conveyor unit, a measuring unit to record ventilation parameters, an evaluation unit to calculate the total air volume conveyed, a transmission unit to send data to a validation unit for economic valuation, and an invoicing system to generate invoices based on the air volume flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users purchase fans or air conveyor units to obtain air volume flow, then they can receive the required air quantity, but they have to purchase technical components which increases cost and complexity
Solution Approach 1:
The patent extracts the core function of air conveyance from the fan equipment itself and separates it as a service. Instead of users needing to own and operate fans, the system measures and invoices air volume flow, allowing users to receive air quantity as a pure service without technical equipment complexity
Solution Approach 2:
The patent introduces measurement and evaluation units as intermediaries between the air conveyor unit and the user. These intermediaries measure ventilation parameters, calculate air volume flow, and enable invoicing, thereby facilitating the separation of air conveyance service from equipment ownership
2Adaptability or versatility
If facility operators provide air quantity as a service, then users can receive required air volume without purchasing equipment, but there is a lack of devices to record and invoice the air quantity
Solution Approach 1:
The patent creates a multi-functional device that combines air conveyance, measurement, evaluation, and invoicing capabilities. The air quantity recording and invoicing device serves multiple functions: it conveys air, measures ventilation parameters, calculates air volume flow, and generates invoices, thereby enabling facility operators to provide air quantity as a service with a single integrated system
Solution Approach 2:
The system enables automatic measurement and invoicing of air quantity through integrated measurement and evaluation units. The device automatically records ventilation parameters, calculates air volume flow over time periods, and generates invoices without manual intervention, allowing the system to serve itself in terms of billing and accounting
3Measurement precision
If air volume flow is measured and invoiced over time periods, then accurate billing can be provided, but measurement and evaluation of ventilation parameters is required which adds system complexity
Solution Approach 1:
The patent merges the measurement unit and evaluation unit into an integrated system. The measurement unit records ventilation parameters and the evaluation unit processes these measurements to calculate air volume flow, combining multiple functions in a unified device that reduces overall system complexity while maintaining measurement precision

AI summary
An apparatus and a method for ascertaining and billing for a volume of air generated by an air-conveying device. The air quantity ascertaining and billing apparatus has an air-conveying device generating an air volume flow through an air passage. A measuring device measures air-related parameters of the particular air volume flow. An analysis unit analyzes the measured parameters, in order to determine the total air volume that was conveyed by the air conveying device through the air passage over a period. A transfer device transfers the value determined for the air volume by the analysis unit to a validation device. The validation device links the air volume flow or the determined air volume to an economic value, in order to obtain a billing value for the generated air volume.
