Air conditioning seat
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air conditioning seat technologies fail to provide comprehensive warming or cooling of the legs, leaving them uncomfortable, as they primarily focus on cooling or partially warming only the parts of the legs that contact the ottoman.
Innovation Solution
An air conditioning seat design that includes a seat cushion, seat back, lateral members such as armrests or vertical wall members, and air ducts to direct temperature-adjusted air towards the knees and lower leg portions, ensuring overall warming or cooling of the legs by blowing air from strategically positioned outlets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If air is blown from conventional positions (neck, torso, feet) then cooling or partial warming is achieved, but the legs cannot be overall warmed or cooled
Solution Approach 1:
The patent introduces air outlets on the lateral side of the seat (armrest or side wall) to blow air horizontally towards the leg, adding a lateral dimension to the conventional vertical air flow. This enables the air to wrap around the leg from multiple directions, achieving overall leg temperature control that was not possible with conventional front-only air outlets.
2Temperature
If air outlets are positioned only at the front of the seat cushion then air reaches the feet, but the knees and lower leg portions remain uncovered
Solution Approach 1:
The patent divides the leg into multiple segments (knee, lower leg, foot) and provides dedicated air outlets for each segment. The lateral member air outlet targets the knee and lower leg, while the front cushion air outlet targets the foot, creating a segmented approach to comprehensive leg coverage.
Solution Approach 2:
By adding lateral air outlets at the armrest or side wall position, the patent creates a multi-directional air delivery system that wraps air around the leg from both lateral and front directions, significantly improving coverage of the knee and lower leg areas.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design effectively wraps the legs with temperature-adjusted air, enhancing comfort by ensuring comprehensive warming or cooling, particularly by positioning air outlets on the front side of the seat cushion to target the knees and lower leg portions.
Implementation Method 1
temperature-adjusted air whose temperature is adjusted by an air conditioning apparatus
Implementation Method 2
temperature-adjusted air whose temperature is adjusted by an air conditioning apparatus
Implementation Method 3
a first air duct which is provided in the lateral member and is configured to guide the temperature-adjusted air towards the seated person
Implementation Method 4
the temperature-adjusted air is configured to be directed and blown out towards at least one of a knee and a lower leg portion of a leg of the seated person

AI summary
An air conditioning seat configured to blow temperature-adjusted air and including: a seat including a seat cushion and a seat back; a lateral member which is provided along the seated person seated on the seat on a lateral side of the seated person; a first air duct which is provided in the lateral member and is configured to guide the temperature-adjusted air towards the seated person; and a first air outlet from which the temperature-adjusted air is configured to be blown out from first the air duct, wherein the temperature-adjusted air is configured to be directed and blown out towards at least one of a knee and a lower leg portion of a leg of the seated person through the first air outlet, the at least one of the knee and the lower leg portion being positioned on a front side than a front end of the seat cushion.
