Automobile Seat Sweat Sensor Comfort Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automobile seats with climate control systems rely on ambient temperature and humidity sensors, leading to complex control mechanisms and reduced comfort independence from external conditions.
Innovation Solution
A vehicle seat with sweat sensors that measure biomarkers to control localized climate control and massage functions, providing independent comfort management based on occupant-specific data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ambient temperature and humidity sensors are used to control climate control means, then the control system can function, but the control becomes complex and dependent on exterior parameters
Solution Approach 1:
The patent extracts the control system from dependence on ambient parameters by removing the requirement for ambient temperature and humidity sensors. Instead, it uses only sensors placed in the seat to measure occupant-related parameters (temperature, humidity, presence), thereby simplifying the control system while improving reliability by making comfort control independent of exterior conditions.
Solution Approach 2:
The seat system serves itself by using sensors integrated directly into the seat to measure occupant parameters. The control means are driven based on measurements from these seat-integrated sensors, allowing the system to autonomously regulate comfort without external reference measurements, thus reducing complexity while maintaining reliability.
2Measurement precision
If ambient sensors are required for comparison with seat sensors, then reference measurements can be obtained, but the control mechanism becomes more complex
Solution Approach 1:
The patent removes the requirement for ambient sensors entirely, extracting the reference measurement function from the external environment. Instead of comparing seat sensor readings with ambient sensor readings, the system uses the seat sensors themselves to directly measure occupant parameters, eliminating the need for complex comparison logic and reducing overall system complexity.
Solution Approach 2:
The patent introduces the seat itself as an intermediary between the occupant and the measurement system. By placing sensors directly in the seat in contact with or near the occupant, the seat acts as a mediator that provides direct access to occupant parameters without requiring external ambient measurements for reference.
3Adaptability or versatility
If climate control is based on ambient parameters, then the system can operate, but comfort independence from external conditions is reduced
Solution Approach 1:
The system achieves comfort independence by serving itself through direct measurement of occupant parameters via seat-integrated sensors. The control means are driven based on these direct measurements without requiring ambient parameter data, allowing the system to adapt to occupant needs independently of external conditions and optimize energy consumption by acting only when and where needed.
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
Enhances comfort reliability by using sweat sensors to drive individualized climate control and massage actions, minimizing energy consumption and optimizing comfort regardless of ambient conditions.
Implementation Method 1
the measurement of the sweat from the occupant of the seat is done with at least one sweat sensor disposed in the seat
Data Source
AI summary
A vehicle seat has at least one occupant comfort actuator suited for acting on a part of the body of an occupant of the seat. The actuator is driven based on at least one measurement of one sensor of sweat from the occupant of the seat.
