Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If software applications directly interface with diverse hardware APIs using different communication protocols, then compatibility with various hardware devices is achieved, but latency increases and code complexity increases

Engineering Contradiction:

Improvecompatibility with hardware APIsVSAvoidlatency

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent introduces a gateway service as an intermediary component between software applications and hardware APIs. This gateway translates communication protocols and standardizes interactions, eliminating the need for software applications to directly handle multiple different hardware protocols. The gateway acts as a mediator that converts diverse hardware API protocols into a unified communication interface, thereby reducing latency and code complexity while maintaining compatibility with various hardware devices.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system architecture is segmented into distinct layers: the hardware API layer, the gateway service layer, and the software application layer. This segmentation isolates protocol complexity to the gateway layer, allowing software applications to interact with a simplified interface. The gateway handles protocol translation and hardware-specific logic separately, reducing the computational overhead and latency experienced by applications when interfacing with diverse hardware APIs.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If software applications implement checks for each hardware API to identify communication protocols, then compatibility with various hardware devices is achieved, but code complexity increases

Engineering Contradiction:

Improvecompatibility with hardware APIsVSAvoidcode complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The gateway service serves as an intermediary that centralizes protocol identification and translation logic. Instead of software applications implementing checks for each hardware API, the gateway automatically identifies the required communication protocol and performs the necessary translations. This eliminates complex protocol-detection code from applications while maintaining support for multiple hardware APIs through a unified interface.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The gateway service provides a universal interface that works with multiple hardware APIs through a single standardized communication method. Rather than requiring separate implementation logic for each hardware protocol, the gateway handles multiple protocols through a unified mechanism, reducing code complexity in software applications while maintaining broad hardware compatibility.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of operation

If conventional API gateway services are used in cloud-based architecture, then resource management is simplified, but compatibility with hardware APIs in edge devices is reduced

Engineering Contradiction:

Improveresource managementVSAvoidcompatibility with hardware APIs

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The gateway service is adapted for edge device environments by implementing local resource management strategies suitable for constrained hardware. Rather than using cloud-based gateway services that assume abundant resources, the patent optimizes the gateway for edge deployment with limited computing power and memory. This local adaptation maintains ease of resource management while enhancing compatibility with hardware APIs specific to edge devices.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The gateway service parameters and configuration are optimized for edge device constraints, including adjusted resource allocation, memory management, and processing capabilities. By changing the operational parameters to suit edge environments rather than cloud environments, the system achieves both ease of operation in resource-constrained settings and compatibility with diverse hardware APIs deployed at the edge.

AI summary

A gateway service can be generated by a daemon to facilitate communication for application programming interfaces (APIs) in edge devices. For example, the daemon can monitor a database including one or more configuration files for an API. The daemon can detect an update to a configuration file of the one or more configuration files in the database. In response to detecting the update to the configuration file, the daemon can generate an instance of the gateway service configured to interface between a software application and the API.
