Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Building automation systems require significant calculation resources and on-site reprogramming to adjust to environmental changes, making them inefficient and requiring frequent updates.
Innovation Solution
A method to create a reference data structure that combines setpoint parameters for actuators, allowing for centralized calculation and storage of setpoint values, which are then applied to actuators through a computer system, reducing the need for on-site recalculations and updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If control laws are determined by internal programs in actuators, then actuators can autonomously control building equipment, but calculation resources are consumed and on-site reprogramming is required for environmental modifications
Solution Approach 1:
The patent extracts the control law calculation function from the actuator's internal program and relocates it to an external server. The server generates control laws based on environmental data and transmits them to actuators, eliminating the need for on-site reprogramming while maintaining autonomous control capability.
Solution Approach 2:
The patent introduces a server as an intermediary between environmental sensors and actuator controllers. This mediator receives environmental data, calculates optimal control laws, and transmits them to actuators, resolving the contradiction between autonomous control and reprogramming requirements.
2Ease of operation
If control laws are determined by internal programs, then actuators can operate independently, but frequent environmental changes require repeated on-site reprogramming
Solution Approach 1:
The patent implements preliminary action by having the server continuously monitor environmental data and pre-calculate control laws before they are needed. When environmental conditions change, the server already has updated control laws ready for immediate transmission to actuators, eliminating reprogramming wait time.
Solution Approach 2:
The patent establishes a feedback loop where actuators transmit operational status and environmental sensors provide real-time data to the server. This continuous feedback enables the server to dynamically update control laws without interrupting actuator operation, maintaining independence while adapting to changes.
3Adaptability or versatility
If setpoint parameters are calculated locally at each actuator, then each actuator can adapt to its specific conditions, but significant calculation resources are required at the actuator level
Solution Approach 1:
The patent extracts the computationally intensive setpoint calculation function from individual actuators and relocates it to a server with superior processing capabilities. This allows each actuator to maintain local adaptation while consuming minimal energy, as the server handles the heavy computational load.
Solution Approach 2:
The patent merges the calculation resources of multiple actuators into a centralized server. Instead of each actuator having its own full calculation capacity, the system combines processing power at the server level while maintaining individual actuator adaptability through customized control law transmission.
