Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If detection data is transmitted using existing protocols like HTTP or MQTT, then the system can achieve broad compatibility and ease of operation, but the power consumption increases and battery life decreases

Engineering Contradiction:
ImprovecompatibilityVSAvoidpower consumption
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The patent changes the communication protocol from existing protocols (HTTP, MQTT) to a custom protocol optimized for IoT devices. This protocol uses binary format instead of text-based formats, implements selective data transmission based on event triggers, and optimizes packet structure to reduce transmission overhead, thereby significantly reducing power consumption while maintaining compatibility through standard TCP/IP transport

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent extracts and transmits only the essential detection data elements rather than complete datasets. It implements a filtering mechanism that identifies and transmits only relevant changes or events, removing redundant information transmission that consumes power, while still providing sufficient data for detection model execution

Inventive Principle:
Principle #2Taking out (Extraction)

2Measurement precision

If detection models are executed locally on acquisition devices, then real-time detection accuracy improves, but the device complexity and computational resource requirements increase

Engineering Contradiction:
Improvedetection accuracyVSAvoidcomputational resources
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent segments the detection system into two parts: lightweight feature extraction executed locally on acquisition devices with limited resources, and complex model execution performed on remote servers with充足 computational resources. This segmentation allows accurate detection while keeping local device complexity low

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces an intermediary communication layer that transmits processed detection data from acquisition devices to remote servers. This intermediary mechanism enables the system to leverage remote computational power for complex model execution while keeping local devices simple, maintaining detection accuracy without increasing local device complexity

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If transmission packets include complete detection data, then the receiver can execute detection models independently, but the data transmission volume and network bandwidth consumption increase

Engineering Contradiction:
Improveindependent execution capabilityVSAvoiddata transmission volume
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent extracts and transmits only essential detection data elements required for model execution, removing redundant or unnecessary data. This selective extraction reduces transmission volume while maintaining the receiver's ability to execute detection models independently by providing the minimum necessary data set

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

The invention relates to a method for transmitting type object detection data, the method comprising, after a detection process has been carried out on a captured image, the following steps: if, for the given image, a detection probability of between S and S' has been determined, wherein S' is predetermined to be strictly less than S and strictly positive, performing a step of transmitting at least one portion of the image comprising the detected type object associated with the data indicating at least one identifier of the detected type object, the detection probability of the object and a geographical position, and, before the transmission step is performed, selectively compressing the image portion according to the current state of the transmission link, regardless of whether the state meets the predefined threshold transmission conditions; after the compression step, transmitting the compressed image portion.
