Personal heating ventilation and air conditioning system in aircraft seat
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aircraft cabin climate control systems lack personalized control, often resulting in passengers experiencing discomfort due to inadequate air flow and temperature distribution, particularly affecting the back and other pressure points during flights.
Innovation Solution
A personal heating ventilation and air conditioning (HVAC) system for aircraft seats, featuring a heating/cooling device with multiple branches and sub-branches that provide adjustable air flow paths, controlled by a controller or mobile devices, integrated into seat components like cushions, back supports, and headrests, with outlets or holes for air expulsion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cabin-wide temperature control is used, then energy consumption is reduced and system complexity is lowered, but personalized comfort control is insufficient
Solution Approach 1:
The cabin climate control system is segmented into individual seat-level units, each with its own heating/cooling device, branches, and sub-branches. This allows personalized climate control for each passenger while maintaining manageable system complexity through modular design.
Solution Approach 2:
The system transitions from traditional cabin-wide (macro) temperature control to seat-level (micro) personalized control by adding a new dimension of control granularity. The multi-level branching structure enables air distribution across different spatial dimensions within each seat.
2Area of stationary object
If traditional gaspers are used, then the system structure is simple, but air flow coverage is insufficient and cannot reach back and pressure points
Solution Approach 1:
The air distribution system is divided into multiple branches and sub-branches that extend to different body areas (back, pressure points, head). This segmented approach enables comprehensive coverage of the entire seating area rather than concentrating flow at a single gasper location.
Solution Approach 2:
Different branches and sub-branches are directed to provide air flow to specific local areas of the passenger body (backrest, cushion, headrest). Each zone receives tailored air flow to address local comfort needs, creating localized climate zones throughout the seat.
3Stability of the object's composition
If single-point temperature control is used, then control device complexity is low, but temperature distribution uniformity is poor
Solution Approach 1:
The temperature control system is segmented into multiple independent heating/cooling devices, each serving specific zones through dedicated branches and sub-branches. This enables uniform temperature distribution across different body areas by allowing independent control of each zone rather than relying on a single control point.
