Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air conditioning systems require exclusive human detection sensors or lenses for each outlet area, leading to increased costs and limitations in adapting to different configurations, such as systems with varying numbers of outlet areas.
Innovation Solution
The configuration includes a plurality of human detection sensors installed in a decorative panel of an indoor air conditioner unit, each paired with a lens to detect specific ranges, using general-purpose sensors and lenses to cover multiple ranges, with infrared shielding and transmission covers to optimize detection within desired areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If exclusive human detection sensors or lenses are used for each outlet area, then detection precision for each outlet area is improved, but device complexity and cost increase
Solution Approach 1:
The patent applies universality by using a single human detection sensor that can detect multiple outlet areas through different detection ranges. Instead of requiring exclusive sensors for each outlet area, one sensor with multiple detection ranges (achieved through lens configurations) serves all outlet areas, reducing device complexity while maintaining detection precision
Solution Approach 2:
The patent segments the detection function by dividing the detection space into multiple ranges corresponding to different outlet areas. A single sensor is divided into multiple detection zones through optical elements, allowing each zone to independently monitor a specific outlet area without requiring separate physical sensors
2Area of stationary object
If exclusive human detection sensors are used for each outlet area, then detection coverage for each outlet area is improved, but adaptability to different air conditioning systems deteriorates
Solution Approach 1:
The patent creates a universal detection system where a single human detection sensor with multiple detection ranges can be applied to various air conditioning system configurations. The system adapts to different numbers and arrangements of outlet areas by adjusting which detection ranges are activated, rather than requiring exclusive sensors for each configuration
Solution Approach 2:
The patent introduces dynamics by making the detection system configurable and adaptable. The human detection sensor can dynamically adjust its effective detection coverage by activating or deactivating specific detection ranges based on the actual outlet area configuration, enabling the same sensor to serve different system layouts
