Heated Interior Lining for Rapid Vehicle Cabin Warm-Up
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heating systems in vehicles and aircraft are inefficient at quickly warming the interior, especially at low temperatures, and can produce harmful waste gases when using auxiliary heaters, and are not effective for electric vehicles which lack sufficient engine heat.
Innovation Solution
An interior lining system comprising a carrier, a heating layer, and an upper layer, where the heating layer is integrated between the carrier and the upper layer, forming a layer composite that uses thermal radiation to rapidly heat the vehicle interior, with a heating wire embedded in a non-woven fabric and optionally surrounded by a foam layer for enhanced heat distribution and retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If auxiliary heaters are used to pre-heat vehicles, then the vehicle interior can be heated quickly, but harmful waste gases are produced that contaminate the ambient air
Solution Approach 1:
The harmful combustion process is extracted and removed from the vehicle interior heating system. Instead of using combustion-based auxiliary heaters that produce waste gases, the patent employs electric heating elements that generate heat without combustion, thereby eliminating the production of harmful exhaust gases while maintaining effective interior heating capability
Solution Approach 2:
The mechanical/chemical combustion system is replaced with an electrical heating system. The patent substitutes the combustion-based auxiliary heater with electric heating elements integrated into the seat and steering wheel, replacing the chemical energy conversion process with direct electrical resistance heating that produces no exhaust gases
2Temperature
If ventilation heaters are used to heat the vehicle interior, then the interior can be warmed, but a considerable length of time passes before the engine releases sufficient heat
Solution Approach 1:
Heating action is performed in advance and directly at the points of contact rather than waiting for engine heat. The patent integrates heating elements into the seat and steering wheel that can be activated immediately, providing preliminary heating action directly where needed without waiting for the engine to generate sufficient heat
Solution Approach 2:
Electric heating elements serve as an intermediary between the power source and the operator's body. Instead of relying on the engine as an intermediate heat source that takes time to warm up, direct electric heating elements are introduced as intermediaries that convert electrical energy to thermal energy instantly at the contact points
3Temperature
If electric heating devices are installed in the ventilation duct, then heating can be provided in electric vehicles, but the heating effect is limited and does not warm the entire interior quickly
Solution Approach 1:
Heating is applied locally at the most critical contact points rather than attempting to heat the entire interior uniformly. The patent places heating elements specifically in the seat and steering wheel where the operator has direct contact, concentrating heating power where it is most needed and perceived, thereby achieving effective heating with lower overall power requirements
Solution Approach 2:
The heating system is segmented into multiple independent heating zones rather than using a single centralized heater. The patent divides the heating function into separate heating elements in the seat, steering wheel, and potentially other contact points, allowing each segment to operate independently and efficiently heat its specific zone
