Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle heater devices inefficiently utilize heat quantity as radiant heat from one surface is often wasted due to obstruction by the back of the front seat, and the lower body of the user is difficult to warm effectively.
Innovation Solution
A heater device with a planar heating element having a first heat radiation surface at a higher temperature for non-contact warming and a second heat radiation surface at a lower temperature for contact warming, integrated with a slide rail mechanism and blowout port for adjustable positioning and air conditioning, allowing efficient heat distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If radiant heat is emitted from one surface of the heating element, then the user's upper body can be warmed, but heat is wasted due to obstruction by the back of the front seat and the lower body cannot be warmed effectively
Solution Approach 1:
The heating element is divided into two independent heat radiation surfaces (first and second surfaces) that can emit heat in opposite directions. This segmentation allows the first surface to warm the upper body while the second surface warms the lower body, eliminating heat waste and expanding warming coverage to the entire body.
Solution Approach 2:
The heating element utilizes both surfaces (front and back) for heat radiation, transitioning from single-sided to double-sided heating. This dimensional change enables heat emission in two opposite directions, allowing simultaneous warming of upper and lower body areas that were previously inaccessible.
2Loss of energy
If a single heat radiation surface is used, then the device structure is simple, but heat distribution efficiency is low
Solution Approach 1:
The heater panel is segmented into two functional surfaces: the first heat radiation surface for primary heating and the second heat radiation surface for supplementary heating and lower body warming. This segmentation improves heat distribution efficiency by utilizing both surfaces of the heating element, while the overall panel structure remains relatively simple.

AI summary
A heater device for warming a user has a heater panel including a planar heating element which generates heat by energization, a first heat radiation surface formed on one surface side of the heating element, and a second heat radiation surface formed on the other surface side of the heating element. The temperature of the first heat radiation surface is higher than the temperature of the second heat radiation surface. In the heater panel, the first heat radiation surface is configured as a non-contact heater that warms the user in a non-contact manner, and the second heat radiation surface is configured as a contact heater that warms the user in a contact manner.
