Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the ceiling embedded-type air conditioner uses fixed angle deflectors, then the structure is simple and easy to manufacture, but it cannot automatically adjust the direction of guiding airflow according to the position of the human

Engineering Contradiction:
Improveairflow direction adjustment capabilityVSAvoiddeflector control system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies the dynamics principle by transforming the fixed deflector structure into a dynamically adjustable one. The deflector angle is no longer fixed but can be dynamically changed based on real-time human position detection. The control system calculates the optimal deflector angle according to the detected human position parameters (distance, angle, height) and adjusts the deflector accordingly, enabling the airflow direction to adapt dynamically to human movement.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements feedback by using a millimeter wave human sense module to continuously detect human position and feed this information back to the control system. The control system processes the detected position data, calculates the appropriate deflector adjustment angle, and sends control signals to adjust the deflector. This closed-loop feedback mechanism enables automatic airflow direction adjustment according to human position.

Inventive Principle:
Principle #23Feedback

2Adaptability or versatility

If the ceiling embedded-type air conditioner adds automatic airflow adjustment capability, then it can meet various actual needs, but the device complexity increases

Engineering Contradiction:
Improvehuman position-based airflow controlVSAvoidcontrol system structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical adjustment mechanisms with a combination of millimeter wave detection and electronic control. Instead of using complex mechanical linkages or motors for deflector adjustment, the system uses millimeter wave radar for non-contact human position detection and electronic control signals to adjust the deflector angle, significantly reducing mechanical complexity while achieving precise airflow control.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the control parameter from fixed mechanical settings to dynamically adjustable angular parameters based on detected human position. The system detects human position parameters (distance, angle, height) and transforms these into deflector adjustment parameters, enabling flexible airflow direction control without complex mechanical reconfiguration mechanisms.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If the ceiling embedded-type air conditioner uses fixed blowing angles, then the manufacturing cost is low, but it cannot track and follow human movement

Engineering Contradiction:
Improveautomatic airflow trackingVSAvoiddetection and control system
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent applies self-service by enabling the air conditioner to automatically detect human position and adjust its own airflow direction without external control. The millimeter wave human sense module continuously monitors human position, and the control system automatically calculates and adjusts the deflector angle to track human movement, making the system self-regulating and eliminating the need for manual intervention.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent introduces a millimeter wave human sense module as an intermediary to detect human position non-invasively. This intermediary device enables the air conditioner to感知 human presence and position without direct contact or complex interaction mechanisms, serving as a bridge between the user and the control system while keeping the overall device complexity manageable.

Inventive Principle:
Principle #24Intermediary (Mediator)
