Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air conditioners for vehicle seats lack the ability to efficiently adjust airflow direction based on user preferences, ambient temperature, and seat surface temperature, leading to inconsistent climate control in both summer and winter.
Innovation Solution
An air conditioner with a switching device that allows for reversible airflow direction without altering the discharge direction of the air feeder, featuring an electronic or manual control system to adjust airflow depending on user choice, ambient temperature, and seat surface temperature, ensuring optimal climate control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If air conditioning systems use fixed airflow direction, then the system structure is simple, but the climate control consistency deteriorates
Solution Approach 1:
The patent implements a switching device with movable components (flaps, valves, or redirectors) that dynamically adjust airflow direction based on temperature sensor feedback. This dynamic adjustment mechanism allows the system to adapt between different airflow patterns (e.g., directed toward feet vs. upper body) to maintain consistent climate control across varying thermal conditions, resolving the contradiction between structural simplicity and climate control consistency.
2Adaptability or versatility
If air conditioning systems add switching devices for airflow direction control, then climate control adaptability improves, but device complexity increases
Solution Approach 1:
The patent employs temperature sensors positioned at multiple locations (seat, ambient air, exhaust air) that automatically detect thermal conditions and trigger appropriate airflow direction changes without user intervention. The system self-adjusts by comparing temperature readings and activating the switching device when temperature differences exceed predetermined thresholds, thereby improving climate control adaptability while minimizing the need for complex manual control interfaces.
Solution Approach 2:
The system incorporates a feedback loop where temperature sensors continuously monitor thermal conditions and provide signals to the control unit, which then adjusts airflow direction via the switching device. This closed-loop feedback mechanism enables the system to respond adaptively to changing thermal environments, improving climate control versatility while keeping the control logic relatively simple through threshold-based decision-making.
3Measurement precision
If air conditioning systems operate without directional control, then energy consumption is lower, but temperature management precision deteriorates
Solution Approach 1:
The patent implements a threshold-based control strategy where the switching device activates only when temperature differences between sensor locations exceed predetermined thresholds. This partial action approach means the system maintains precise temperature management by adjusting airflow direction only when necessary, rather than continuously, thereby improving temperature management precision while avoiding excessive energy consumption from constant switching operations.
