Building Device Control Using Reusable Validation Tokens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing building control systems experience slow and repetitive control processes when adjusting building devices remotely, lacking efficient validation and authorization mechanisms.
Innovation Solution
A method and system that utilize a token-based validation process, where a user device receives a token from a previous action request, validates it within the building device, and adjusts the device only when validated, with optional acknowledgement and alarm features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a token-based validation process is implemented, then control speed and efficiency improve, but system complexity increases
Solution Approach 1:
The system performs preliminary actions by generating and storing tokens during previous action requests. These tokens are then reused for subsequent control operations, eliminating the need for repeated full authentication processes and thereby improving control speed while managing system complexity through pre-computed validation data.
Solution Approach 2:
The invention uses token copies from previous action requests to validate and execute subsequent building device adjustments. Instead of re-transmitting or re-validating the entire authorization data, the system creates and validates simplified token copies, significantly improving control efficiency while reducing the computational burden on the system.
2Ease of operation
If remote control of building devices is enabled, then user convenience improves, but control process becomes slow and repetitive
Solution Approach 1:
The system performs preliminary authentication and generates tokens in advance during the first action request. Subsequent remote control operations simply need to present these pre-generated tokens for validation, eliminating repeated authentication steps and reducing the time required for each control action while maintaining user convenience.
Solution Approach 2:
The token-based system enables continuous rapid control operations once the initial authentication is complete. The validated tokens can be reused for multiple sequential adjustments of building devices, maintaining uninterrupted control flow and eliminating the repetitive delays that would otherwise occur with repeated full authentication cycles.
3Reliability
If token validation is required for each adjustment, then security improves, but control process becomes repetitive
Solution Approach 1:
The system creates simplified token copies from the original authentication data. These token copies contain sufficient validation information to maintain security but are much lighter and faster to process than full authentication credentials. This allows rapid validation of multiple control requests while preserving security through the token verification mechanism.
Solution Approach 2:
The invention transforms the authentication parameter from full credential verification to simplified token validation. By changing the validation parameter from comprehensive authentication data to condensed token representations, the system maintains security requirements while dramatically improving control efficiency and reducing the repetitiveness of the validation process.

AI summary
A method of controlling a building system is provided. The method comprising: receiving an action request to adjust a building device from a user device; obtaining a token from a previous action request from the user device to adjust the building device when a token exists from a previous action request; transmitting the token for validation within the building device; and adjusting the building device when the token has been validated.
