Solution Overview
Problem
Existing automobile seats with both heating and ventilation systems face interference issues during assembly and result in higher costs due to the need for two independent temperature control systems.
Innovation Solution
An integrated temperature adjusting system comprising a convertible cooling module and a heating module connected in series, utilizing a semiconductor cooler and a heater, respectively, with a fan to control airflow for both heating and cooling functions, eliminating the need for separate heating and ventilation devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a heating pad and a separate ventilation device are installed in the seat, then both heating and cooling functions are achieved, but device complexity and assembly interference increase
Solution Approach 1:
The patent combines the heating pad and ventilation device into a single integrated temperature adjusting system. The heating module (containing heating element and insulating layer) and cooling module (containing airflow passage and breathable layer) are merged into one unified structure that can provide both heating and cooling functions through a single device assembly, eliminating the need for separate independent systems.
Solution Approach 2:
The integrated temperature adjusting system is designed to perform multiple functions: heating through the heating module, cooling through the cooling module with airflow passage, and insulation through the insulating layer. This universal system replaces what would traditionally require separate dedicated devices for each function, achieving multi-functionality within a single structural framework.
2Adaptability or versatility
If two independent temperature control systems (heating and ventilation) are provided, then comprehensive temperature adjustment is achieved, but manufacturing cost increases
Solution Approach 1:
By merging the heating and ventilation systems into a single integrated temperature adjusting system with shared structural components (seat cushion integration, unified housing, combined airflow and heating pathways), the manufacturing process is simplified. This reduces the number of separate assemblies required, lowers material costs, and decreases assembly steps compared to producing and installing two independent systems.
3Adaptability or versatility
If separate heating and ventilation devices are installed, then complete temperature control is achieved, but assembly interference occurs
Solution Approach 1:
The integration of heating and ventilation functions into a single temperature adjusting system eliminates assembly interference by reducing the number of separate components that need to be installed. The unified structure with pre-coordinated airflow passages, heating elements, and breathable layers allows for streamlined installation as one complete assembly rather than multiple separate devices that would interfere with each other during installation.

AI summary
An automobile seat and an automobile are provided. The automobile seat comprises a seat cushion and a backrest, and at least one of the seat cushion and the backrest is provided with a temperature adjusting system comprising a temperature adjusting device and a fan (300). In the automobile seat, the traditional heating pad and ventilation device are replaced by providing, in a temperature adjusting system, a fan (300) and a temperature adjusting device formed by serially-connected devices wherein a convertible cooling module (100) and a heating module (200) are connected, thereby achieving the integrated design of ventilation heating and cooling, avoiding the interference between the two sets of devices, thus reduces manufacturing and processing costs.
