Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If wired charging is used, then charging function is provided, but manual intervention is required during calls and charging line needs to be unplugged

Engineering Contradiction:

Improvecharging operation convenienceVSAvoidtime for unplugging and plugging charging line

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The terminal support system automatically detects call states and adjusts terminal positioning without user intervention. The control module receives detection signals about call states and automatically controls the force generation module to adjust terminal position, eliminating the need for manual unplugging and plugging of charging lines.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The detection module continuously monitors terminal states including call states and charging states, sending detection signals to the control module which then automatically adjusts the terminal position based on the detected state, creating a closed-loop feedback system that automates the charging process.

Inventive Principle:

Principle #23Feedback

2Ease of operation

If wireless charging is used, then charging function is provided, but terminal needs to be picked up and accurately placed back

Engineering Contradiction:

Improvecharging operation convenienceVSAvoidplacement accuracy on charging area

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The terminal support system automatically detects when a call is incoming and adjusts the terminal position to an appropriate state without requiring the user to pick up and manually reposition the terminal, eliminating the need for accurate manual placement.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system replaces manual mechanical placement with automatic force generation using electromagnets. The force generation module applies magnetic forces to automatically position the terminal on the placing surface, substituting the need for manual mechanical placement with automated electromagnetic actuation.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Loss of information

If manual screen checking is used, then charging completion can be known, but user experience is not humanized

Engineering Contradiction:

Improvecharging progress informationVSAvoiduser interaction convenience

Core Design Contradiction:

Loss of informationVSEase of operation

Solution Approach 1:

The system uses different colored lights to indicate charging states and progress. The detection module detects charging completion and the control module controls indicators to display visual feedback, allowing users to know charging status without manually checking the screen.

Inventive Principle:

Principle #32Color changes

Solution Approach 2:

The system provides automatic visual feedback about charging progress and completion status through indicators controlled by the control module based on detection signals from the detection module, eliminating the need for manual screen checking and providing intuitive user feedback.

Inventive Principle:

Principle #23Feedback
