HVAC Event Memory Buffers for Tiered User and Service Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
HVAC systems face a challenge in presenting varying levels of operational detail to different users, with homeowners requiring minimal information and service personnel needing more detailed data for diagnosis and improvement.
Innovation Solution
An apparatus and method utilizing two memory buffers within the HVAC system to store and manage event information, with a first buffer providing less complex information for users and a second buffer storing more detailed data for authorized personnel, allowing controlled access and independent resetting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If detailed event information is stored and presented to all users, then servicemen can easily diagnose and service the system, but homeowners become confused and frustrated by too much information
Solution Approach 1:
The patent divides the single memory buffer into multiple memory buffers (first memory buffer for simplified information, second memory buffer for detailed information). This segmentation allows different user roles to access appropriately detailed information levels, resolving the contradiction between providing comprehensive data for servicing while maintaining simplicity for end users.
2Ease of operation
If minimal information is presented to homeowners, then user experience is enhanced, but servicemen lack sufficient data for diagnosis and improvement
Solution Approach 1:
The patent applies local quality by assigning different information characteristics to different memory buffers. The first memory buffer contains simplified, user-friendly information appropriate for homeowners, while the second memory buffer contains comprehensive, detailed information suitable for servicemen. This local differentiation of information quality resolves the contradiction between user experience and servicing needs.
3Adaptability or versatility
If a single memory buffer stores all event information, then all data is available for servicing, but the system cannot present differing levels of detail to different users
Solution Approach 1:
The patent segments the single memory buffer into multiple specialized buffers that preserve all event information while organizing it by detail level. This segmentation enables the system to adaptively present appropriate information levels to different users without losing any underlying data, thus resolving the contradiction between adaptability and information preservation.

AI summary
An apparatus for storing event information relating to operation of an HVAC system includes: (a) at least one memory controller coupled with the HVAC system for receiving the event information; and (b) at least one memory unit coupled with the at least one memory controller. A first memory unit of the at least one memory unit is configured for receiving first selected information of the event information for accessing by at least one of a first party and a second party. A second memory unit of the at least one memory unit is configured for receiving second selected information of the event information for accessing by the second party.
