Vehicle Seat Neck Temperature Control Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing neck temperature control devices in vehicles often fail to coordinate the operation of air conveying and temperature control devices, leading to uncomfortable temperatures, air flow issues, and excessive noise, which reduces user comfort.
Innovation Solution
A control device automatically coordinates the operation of the air conveying and temperature control devices, including preheat, start-up, and continuous operating modes, to ensure optimal temperature control and air flow, using features like deactivation of the air conveying device during preheat to prevent uncomfortable temperature sensations and reduce power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the air conveying device and temperature control device are operated independently, then each device can function with simple control logic, but the temperature control in the neck region becomes unsuitable and user comfort is reduced
Solution Approach 1:
The control logic for the air conveying device and temperature control device is merged into a unified control system that coordinates their operation. The control unit integrates control signals for both devices, ensuring they work together harmoniously to provide suitable neck region temperature control while managing overall system complexity.
Solution Approach 2:
The system performs preliminary temperature control of the air before it is conveyed to the neck region. The temperature control device pre-adjusts the air temperature according to predetermined criteria, ensuring that when the air is subsequently conveyed by the air conveying device, the neck region receives air at the appropriate temperature, thereby preventing uncomfortable sensations.
2Speed
If the air conveying device conveys air immediately upon activation, then the response time is fast, but the air temperature is unsuitable causing uncomfortable sensations
Solution Approach 1:
The system performs preliminary temperature control of the air before it is conveyed to the neck region. The temperature control device pre-adjusts the air temperature according to predetermined criteria, ensuring that when the air is subsequently conveyed by the air conveying device, the neck region receives air at the appropriate temperature, thereby preventing uncomfortable sensations.
Solution Approach 2:
The control system dynamically adjusts the operation of the temperature control device and air conveying device based on real-time conditions. The control unit modulates the temperature control intensity and air conveyance timing to ensure that air is only conveyed when it has reached the suitable temperature, balancing rapid response with temperature appropriateness.
3Productivity
If both devices are activated simultaneously at high power, then the temperature control effect is achieved quickly, but strong current peaks occur and power consumption increases
Solution Approach 1:
The control system employs periodic or staged activation of the temperature control device and air conveying device rather than simultaneous full-power activation. By controlling the devices in sequence or with modulated power levels, the system achieves the required temperature control effect while avoiding strong current peaks and reducing overall power consumption.
Solution Approach 2:
The control system dynamically adjusts the operation of the temperature control device and air conveying device based on real-time conditions. The control unit modulates the temperature control intensity and air conveyance timing to ensure that air is only conveyed when it has reached the suitable temperature, balancing rapid response with temperature appropriateness.
4Ease of operation
If the air conveying device operates without coordination, then the air flow is continuous and simple to control, but excessive noise is generated reducing comfort
Solution Approach 1:
The control system incorporates feedback mechanisms that monitor the operation of the air conveying device and adjust its operation accordingly. By receiving feedback on air flow conditions and coordinating with the temperature control device status, the control unit can modulate the air conveying operation to reduce noise generation while maintaining adequate air flow for temperature control.
Solution Approach 2:
The control system dynamically adjusts the operation of the temperature control device and air conveying device based on real-time conditions. The control unit modulates the temperature control intensity and air conveyance timing to ensure that air is only conveyed when it has reached the suitable temperature, balancing rapid response with temperature appropriateness.
