Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the communication module is designed inside the electrical device, then the device structure is compact, but the communication module is shielded by the metal shell and interfered by internal components

Engineering Contradiction:
Improvedevice structure compactnessVSAvoidcommunication module reliability
Core Design Contradiction:
Volume of moving objectVSReliability

Solution Approach 1:

The communication module is extracted from the electrical device and integrated into the power cord plug instead. This separates the communication module from the metal shell and internal components that cause shielding and interference, while maintaining overall system compactness by utilizing the power cord plug space.

Inventive Principle:
Principle #2Taking out (Extraction)

2Ease of operation

If the communication module is mounted on the shell of the electrical device, then the communication module is accessible, but the appearance consistency is affected and the overall size is increased

Engineering Contradiction:
Improvecommunication module accessibilityVSAvoidappearance consistency
Core Design Contradiction:
Ease of operationVSShape

Solution Approach 1:

The communication module is merged with the power cord plug structure, combining two functions (power supply and communication) into a single integrated component. This maintains accessibility while preserving the electrical device's appearance consistency and avoiding size increase.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If the antenna is led out separately and mounted outside the electrical device, then the antenna has good signal reception, but the device size is increased and the appearance consistency is affected

Engineering Contradiction:
Improveantenna signal receptionVSAvoiddevice size
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The antenna is nested within the power cord plug structure rather than being mounted externally on the electrical device. This allows the antenna to maintain its signal reception capabilities while being housed in a separate, dedicated space within the power cord plug, avoiding any increase in the electrical device's size or appearance inconsistency.

Inventive Principle:
Principle #7Nested doll (Nesting)

4Reliability

If the communication module is placed outside the electrical device, then the communication module is protected from interference, but additional space is required

Engineering Contradiction:
Improvecommunication module stabilityVSAvoidspace requirement
Core Design Contradiction:
ReliabilityVSArea of stationary object

Solution Approach 1:

The power cord plug is designed to serve multiple functions: power supply and communication. By integrating the communication module into the power cord plug, the patent utilizes the existing power cord plug space for dual purposes, avoiding additional space requirements while protecting the communication module from interference.

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