Solution Overview

Problem

Emergency response vehicles face challenges in distinguishing and addressing multiple instances of the same peripheral devices in serial networks, as traditional methods like mechanical dip switches and dedicated ports are prone to failure or costly, and cannot accommodate varying quantities of peripherals effectively.

Innovation Solution

A system and method for configuring and controlling multiple serial devices in emergency response vehicles, where each peripheral device receives and stores a selectable address, allowing a controller to transmit addressable commands, and a computer-readable storage medium with program instructions detects and configures devices, enabling user selection and assignment of unique addresses for each device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If mechanical dip switches are used to address multiple instances of the same peripheral, then individual device identification is enabled, but reliability deteriorates due to susceptibility to failure in rugged environments

Engineering Contradiction:
Improvedevice identificationVSAvoidswitch failure resistance
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent replaces mechanical dip switches with electronic addressing through software configuration. Each peripheral device is assigned a unique address via software, eliminating mechanical components that are prone to failure in rugged emergency vehicle environments. This substitution maintains the ability to individually identify devices while dramatically improving reliability.

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

2Ease of operation

If dedicated ports are provided for each instance of a peripheral, then individual device control is enabled, but device complexity and cost increase

Engineering Contradiction:
Improvedevice control capabilityVSAvoidnumber of ports
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent implements a universal serial communication bus that can address multiple instances of the same peripheral type through software configuration rather than requiring dedicated physical ports. A single controller can manage multiple lights, sirens, or other peripherals by assigning unique addresses to each device, allowing one controller to perform the function of what would traditionally require multiple dedicated port configurations.

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

Solution Approach 2:

The patent merges multiple dedicated port functions into a single serial communication bus. Instead of having separate physical ports for each peripheral instance, multiple devices share the same communication bus with unique addressing, reducing the number of physical connections and controller ports needed while maintaining individual device control capability.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of manufacture

If serial networks are used to control peripherals, then cost is reduced and installation is eased, but the ability to support multiple devices of the same type deteriorates

Engineering Contradiction:
Improveinstallation costVSAvoidmulti-device support capability
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent introduces dynamic software-based addressing to a serial network, allowing the system to adapt and support multiple instances of the same peripheral type. Rather than being limited by fixed hardware configurations, the serial network can dynamically assign and reassign addresses to multiple devices of the same type through software, making the system versatile while maintaining the cost benefits of serial communication.

Inventive Principle:
Principle #15Dynamics
