Solution Overview

Problem

Existing utility device controllers are difficult to position in accessible locations due to environmental conditions and require separate controllers for each device, leading to accessibility and degradation issues, as well as challenges in data communication and monitoring user interactions.

Innovation Solution

A universal controller with a multitasking operating system and native/external control applications that can monitor and control multiple utility devices simultaneously, featuring a robust design with moisture-resistant features and modular I/O boards for various operations, allowing simultaneous operation and monitoring of hospitality or healthcare devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If device-specific controllers are used for each utility device, then each device can be controlled independently, but the system complexity increases and accessibility becomes difficult

Engineering Contradiction:
Improvedevice control reliabilityVSAvoidcontroller system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements a universal controller that can control multiple different utility devices through a standardized interface and communication protocol. The controller includes a processor that can execute different control algorithms for various device types, and a user interface that adapts to display and control parameters for different devices. This eliminates the need for separate dedicated controllers for each utility device while maintaining independent control capability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent consolidates multiple device-specific control functions into a single integrated controller unit. The controller combines processing capabilities, communication interfaces, user interface elements, and environmental protection features into one unified device that can manage multiple utility devices, thereby reducing overall system complexity and improving accessibility.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of operation

If controllers are positioned close to utility devices for accessibility, then user access is improved, but environmental conditions cause controller degradation

Engineering Contradiction:
Improvecontroller accessibilityVSAvoidenvironmental degradation
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent employs a protective enclosure with sealed construction that acts as a barrier between the controller electronics and the harsh environmental conditions. The enclosure includes gaskets, seals, and protective coatings that prevent moisture and steam ingress while allowing the controller to be mounted in accessible locations near utility devices such as water heaters and furnaces.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The controller enclosure creates a protected internal environment that isolates sensitive electronic components from harmful external conditions including moisture, steam, and temperature extremes. This allows the controller to operate reliably in locations that provide good user accessibility while maintaining component integrity.

Inventive Principle:
Principle #39Inert atmosphere (Inert environment)

3Loss of information

If wired connection points are provided for data communication, then data transfer capability is enabled, but moisture can enter and degrade controller components

Engineering Contradiction:
Improvedata communication capabilityVSAvoidcontroller component reliability
Core Design Contradiction:
Loss of informationVSReliability

Solution Approach 1:

The patent replaces wired physical connection points with wireless communication interfaces (such as WiFi, Bluetooth, or other wireless protocols) for data transfer between the controller and external devices. This eliminates openings in the controller enclosure that could allow moisture ingress, while maintaining full bidirectional data communication capability for configuration, monitoring, and control functions.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent uses wireless communication signals as an intermediary medium to transfer data between the controller and external devices without requiring physical connection points. This allows the controller enclosure to remain fully sealed against environmental moisture while enabling complete data exchange functionality through electromagnetic wave transmission.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A controlling and monitoring control application associated with one or more work operations of one or more utility devices is disclosed. The controller is programmed for controlling one or more external work operations associated with one or more utility devices. An I/O board is connected in communication with the primary controller having a module with a plurality of device-specific control applications associated with one or more device-specific work operations. The housing of the controller includes one or more cable access points for plugging a cable into the controller. The cable access points are sealed to prevent water from entering into the housing. A mounting bracket assembly provides flexibility for mounting the controller at various orientations and/or positions. The controller also includes a DC control circuit for controlling backlight luminance over the entire dimming ratio.
