1Productivity
If electric heating elements are used for efficient and clean heating, then heating efficiency is improved, but electromagnetic wave emissions increase causing health concerns
Solution Approach 1:
The patent applies the principle of converting harmful electromagnetic emissions into a beneficial outcome by using pairs of heating elements where the electromagnetic waves from one element cancel out the waves from the other element through opposite phase alternating current, thereby eliminating the harmful effect while preserving the heating function
Solution Approach 2:
The patent implements preliminary anti-action by pre-configuring the heating elements in opposite phase pairs before operation, so that the electromagnetic wave cancellation effect is already in place before the harmful emissions occur, preventing the health concerns associated with electromagnetic exposure
2Object-generated harmful factors
If pairs of heaters powered by opposite phase alternating current are used, then electromagnetic wave emissions are reduced, but device complexity increases
Solution Approach 1:
The patent merges two heating elements into a single functional unit where they work together as an integrated pair, sharing common support structures, insulation, and control, thereby reducing the overall complexity despite the increased number of components needed for electromagnetic cancellation
3Object-generated harmful factors
If EM radiation reduction devices with specific geometries are added, then electromagnetic radiation is mitigated, but manufacturing complexity increases
Solution Approach 1:
The patent employs thin film or shell-like EM radiation reduction devices with specific geometries that can be easily formed and integrated into the heater structure, simplifying the manufacturing process while maintaining the radiation mitigation function

AI summary
Systems may include a heater including a plurality of heating elements that may include a first heating element configured to generate heat based on a first current, and a second heating element configured to generate heat based on a second current. Systems may further include an electromagnetic (EM) radiation reducing device configured to cancel electromagnetic emissions from the heater. The EM radiation reducing device may include a first EM radiation reduction element positioned adjacent to a first side of the heater, and a second EM radiation reduction element positioned adjacent to a second side of the heater, where the first and second EM radiation reduction elements have geometries configured based, at least in part, on the heater.
