Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional heated clothing is used, then heating function is provided, but heating time is long and heating efficiency is low due to controller inability to quickly identify quick charge source

Engineering Contradiction:

Improveheating efficiencyVSAvoidheating time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The controller implements a quick charge identification circuit that continuously monitors the charging interface to detect whether a quick charge source is connected. The controller receives feedback signals from the charging interface and automatically adjusts charging parameters based on the detected quick charge source type, enabling rapid charging and reducing heating time

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent replaces manual charging operation with an automated controller that automatically identifies the quick charge source through electrical signal detection. The controller autonomously determines the charging source type and adjusts charging parameters without user intervention, substituting mechanical/manual charging processes with electronic automation to improve heating efficiency

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If conventional heated clothing with simple structure is used, then manufacturing is easier, but multi-directional heating and infrared physical therapy functions are not provided

Engineering Contradiction:

Improvemulti-directional heating functionVSAvoidgarment structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The heating garment is divided into multiple independent heating zones with separate heating elements positioned at different locations (chest, abdomen, back, limbs). Each heating zone can be independently controlled through separate control circuits, allowing multi-directional heating of different body parts simultaneously or separately, thereby providing versatile heating functions while maintaining manageable structural complexity

Inventive Principle:

Principle #1Segmentation

3Productivity

If quick charge source works for a period of time, then charging is provided, but quick charge source enters sleep mode and outputs no current

Engineering Contradiction:

Improvecharging outputVSAvoidquick charge source working duration

Core Design Contradiction:

ProductivityVSDuration of action of stationary object

Solution Approach 1:

The controller continuously monitors the charging interface and detects the presence of a quick charge source before the quick charge source enters sleep mode. Upon detecting that the quick charge source is about to enter sleep mode or has entered sleep mode, the controller performs preliminary actions by sending wake-up signals to reactivate the quick charge source, ensuring continuous charging output without interruption

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The controller implements continuous monitoring of the charging interface to detect the operational state of the quick charge source. When the quick charge source enters sleep mode, the monitoring circuit detects this state change and provides feedback to the controller, which then sends wake-up signals to restore the quick charge source to active state, maintaining continuous charging capability

Inventive Principle:

Principle #23Feedback
