Solution Overview

Problem

Open-air vehicles like motorcycles face challenges in providing effective cooling for seats due to the high temperature air generated by the engine, which is not suitable for cooling systems that draw air from under the seat.

Innovation Solution

A seat assembly with a heating and cooling module that includes a fan, heat exchanger, and ducts, where air is drawn in from the cooler side of the vehicle, allowing for independent control of heating and cooling, and the configuration of inlet and outlet ducts is optimized to accommodate the vehicle's geometry and heat distribution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If air is drawn from under the seat for cooling, then the cooling system is simple and compact, but the air temperature is too high due to engine heat to provide effective cooling

Engineering Contradiction:
Improveair temperatureVSAvoidcooling effectiveness
Core Design Contradiction:
TemperatureVSEase of operation

Solution Approach 1:

The patent extracts the air intake location from the conventional position (under the seat) to a new position (side of the vehicle). The inlet duct is configured to draw air from the side of the vehicle body, away from the engine compartment, thereby obtaining cooler air for the cooling system while maintaining system compactness.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces an intermediary structure (inlet duct with specific geometry) that mediates between the vehicle's external environment and the seat cooling system. The duct includes a inlet opening at the side of the vehicle body and directs air through a passage to the cooling module, filtering and temperature-regulating the air along the way.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the seat cooling system is designed for enclosed vehicles, then cooling is effective in cars, but the system does not work properly in open-air vehicles like motorcycles

Engineering Contradiction:
Improvevehicle type adaptabilityVSAvoidcooling performance
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent designs a universal seat cooling system that can adapt to different vehicle types (enclosed vehicles like cars and open-air vehicles like motorcycles). The system achieves this through configurable inlet and outlet ducts that can be positioned according to the specific vehicle's geometry and heat distribution characteristics, allowing the same basic cooling module to function reliably across different vehicle platforms.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent implements a dynamic adaptation approach where the duct configuration can be adjusted based on the vehicle type and operating conditions. The system can modify air intake locations, outlet positions, and duct routing to optimize performance for each specific vehicle application, transitioning from a static design to a dynamically adaptable system.

Inventive Principle:
Principle #15Dynamics

3Productivity

If inlet and outlet ducts are configured to optimize cooling, then cooling efficiency improves, but the system complexity increases

Engineering Contradiction:
Improvecooling efficiencyVSAvoidduct configuration complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent applies local quality optimization by configuring the inlet and outlet ducts with specific geometric characteristics suited to different locations in the vehicle. The inlet duct has a specific opening orientation and passage shape optimized for its location, while the outlet duct is configured to direct cooled air to the seat surface effectively. Each duct segment is designed with locally optimized properties rather than using a uniform design throughout.

Inventive Principle:
Principle #3Local quality

AI summary

A seat assembly for a vehicle having a longitudinal axis (30) includes a seat pan (60), a cover support 56 adjacent to the seat pan, and a seat cover (46) that has an upper surface, a first longitudinally extending side surface and a second longitudinally extending side surface. A heating and cooling module (70) is disposed at least partially within the cover support. The seat assembly further comprises a first air inlet (74) in communication with the heating and cooling module. The first air inlet communicates air from a first port in the seat cover to the heating and cooling module.
