Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heating elements are expensive and inefficient in terms of material usage, as they require larger sizes to achieve effective heating without increasing material costs.
Innovation Solution
Incorporating a movable heating element system, where the heating element is attached to or embedded in a machine such as a fan, actuator, or conveyor, allowing it to move behind a heat radiating wall made of conductive materials, thereby distributing heat more evenly across the wall.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the heating element size is increased to improve heating effectiveness, then the heating effectiveness is improved, but the material cost and device complexity increase
Solution Approach 1:
The heating element is made movable rather than stationary, allowing it to dynamically reposition and distribute heat to multiple areas of the wall over time. This dynamic approach enables a smaller heating element to achieve the same overall heating effectiveness that would require a much larger stationary element.
Solution Approach 2:
The heating element operates in the time dimension by moving sequentially across different wall areas, rather than attempting to heat all areas simultaneously. This temporal dimension allows a compact element to cover a large spatial area through sequential heating cycles.
2Reliability
If the heating element size is increased to improve heating effectiveness, then the heating effectiveness is improved, but the material usage increases
Solution Approach 1:
The movable heating element concentrates expensive heating materials in a small component that travels to multiple locations, rather than distributing expensive materials across a large stationary structure. This dynamic concentration of materials achieves comprehensive heating coverage with minimal material consumption.
Solution Approach 2:
The heating element serves multiple wall areas sequentially through its movement, with each position contributing to the overall heating task. This self-service approach allows a single small element to perform the work that would otherwise require many larger elements distributed across the wall.
3Device complexity
If a stationary heating element is used, then the device complexity is low, but the heat distribution uniformity is poor
Solution Approach 1:
The heating element's movement creates dynamic heat distribution across the wall, ensuring uniform heating over time. By sequentially exposing different wall areas to the heat source, the system achieves uniform temperature distribution without requiring a complex array of simultaneous heating elements.
Solution Approach 2:
The heating element follows a periodic motion pattern, systematically visiting different wall areas in sequence. This periodic action ensures that all regions receive consistent heating over time, achieving uniform heat distribution through repeated cycles rather than simultaneous multi-point heating.

Function Achieved in This Case
This approach enhances the effectiveness of heating elements without increasing their size or material usage, ensuring even heat distribution and improved efficiency in heating applications.
Implementation Method 1
A heating element converts electrical energy into heat through Joule heating. Heating of the element occurs from electric current passing through the element and encountering resistance within the element.
Implementation Method 2
The heat radiating wall includes a heat conductive material such as stainless steel, heat-dried clay, glass, or the like, or a combination thereof

AI summary
A heating element can be moved by a machine, such as a machine including a fan, an actuator, or a conveyor. The heating element can be attached to or embedded in a fan or an actuator. Or, the heating element can be attached to or embedded in a conveyor belt of a conveyor. A combination of a heating element and a mover machine can be further combined with a heat radiating wall. The heating element and the machine can be arranged behind the wall. And, when the heating element and the machine are powered on, the heating element converts electrical energy into heat, which increases the temperature of the wall, and the machine moves the heating element to be next to different areas of the wall. This allows for heat to be distributed more evenly to the wall than it would be if the heating element did not move.
