Solution Overview
Problem
Conventional temperature monitoring and control elements in heating systems experience slow response times due to improper mounting, which affects their ability to efficiently monitor and control temperatures, especially in applications like dishwashers and continuous-flow water heaters.
Innovation Solution
The temperature monitoring and control unit is directly fixed to the heating unit using a laser-welded seam, with a beveled edge of less than 90° to facilitate easier laser beam access and reduce the required laser power, ensuring a strong attachment and improved heat transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If temperature monitoring and control elements are fixed with screws to a mounting plate, then the mounting is simple, but the response time becomes too slow
Solution Approach 1:
The patent replaces the mechanical screw-fixing system with a laser-welding system. The temperature monitoring and control element is directly laser-welded to the heating unit, eliminating the mounting plate and screws. This substitution of mechanical fastening with thermal welding achieves both rapid response time (direct thermal contact) and permanent secure attachment.
Solution Approach 2:
The patent merges the temperature monitoring and control element directly with the heating unit through laser welding. By combining these two components into a single integrated assembly with direct thermal contact, the patent eliminates intermediate mounting structures and achieves instantaneous temperature sensing while maintaining structural integrity.
2Use of energy by stationary object
If a beveled edge with angle less than 90° is provided, then laser beam access is facilitated and laser power required is reduced, but the manufacturing complexity increases
Solution Approach 1:
The patent changes the geometric parameter of the mounting surface by providing a beveled edge with an angle less than 90°. This parameter modification allows the laser beam to access the welding area more effectively, reducing the laser power required for welding while enabling direct thermal contact between the temperature monitoring element and heating unit.
