Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
HVAC systems face challenges in manufacturing different embodiments based on desirable sound levels, as determining the specific threshold sound level and configuring the system accordingly can be tedious and costly, with existing methods requiring multiple components and increased manufacturing costs.
Innovation Solution
An HVAC system configured to operate based on selectable operating conditions associated with specific sound levels, using processor circuitry to store and execute instructions that limit sound generation to below a threshold level by adjusting operating parameters of components like compressors, allowing for post-installation adjustment to meet user preferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If different embodiments of HVAC systems are manufactured to meet different sound level requirements, then sound level control is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The patent applies dynamics by making the operating parameters of HVAC components adjustable rather than fixed. The control system can dynamically modify compressor operating parameters (such as speed, pressure, temperature) to achieve different sound levels from a single system embodiment, eliminating the need to manufacture multiple specialized versions.
Solution Approach 2:
The patent changes physical operating parameters of the HVAC system components, particularly the compressor, to control sound levels. By adjusting parameters like operating pressure, temperature, and speed within certain ranges, the system can meet different sound level requirements without requiring different hardware configurations or embodiments.
2Object-affected harmful factors
If multiple components are used to achieve different sound levels, then sound level control is improved, but manufacturing cost increases
Solution Approach 1:
The patent makes a single HVAC system embodiment universal by enabling it to perform multiple sound level functions. The same compressor and control system can operate across different parameter ranges to satisfy various sound level requirements, making one system design suitable for multiple applications without requiring component variations.
Solution Approach 2:
Instead of using different physical components for different sound levels, the patent achieves sound level control by changing the operating parameters of the same components. This approach maintains manufacturing simplicity while providing the flexibility to meet different acoustic requirements through software-controlled parameter adjustment.
3Ease of manufacture
If HVAC systems are configured with fixed operating conditions, then manufacturing simplicity is maintained, but adaptability to different sound level preferences is reduced
Solution Approach 1:
The patent transforms the HVAC system from a static, fixed-configuration design to a dynamic system where operating parameters can be adjusted in real-time. The control system receives sound level preferences and dynamically modifies compressor operations to match user requirements, providing adaptability without complicating the manufacturing process.
Solution Approach 2:
The HVAC system performs self-adjustment based on user-provided sound level preferences. The control system automatically modifies operating parameters without requiring manual reconfiguration or specialized manufacturing for each application, allowing a single standardized system to serve multiple acoustic environments.
