Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional boilers with varying coil diameters for different heating powers incur high production and storage costs due to non-standardized components, and assembly is time-consuming and complex.
Innovation Solution
A boiler design featuring a single frame with a constant outer diameter and adjustable components, allowing for the use of coils with different inner diameters to achieve various heating powers while maintaining standardized production and easy assembly, using a single cylindrical tubular body and adjustable end plate to accommodate different coils.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If coils with different outer diameters are used to achieve different heating powers, then the heat exchanging surface and heating power increase, but the production costs and storage costs increase due to non-standardized components
Solution Approach 1:
The patent applies universality by designing a single standardized boiler body that can accommodate multiple coil configurations with different inner diameters. The boiler body serves multiple functions: containing different sized coils, supporting various heating power outputs, and maintaining structural integrity across different configurations. This eliminates the need for manufacturers to create different boiler bodies for different heating powers, thereby reducing production costs while maintaining the ability to generate various heating powers through coil selection.
2Power
If coils with different outer diameters are used to achieve different heating powers, then the heat exchanging surface increases, but the storage costs increase due to varying boiler dimensions
Solution Approach 1:
The standardized boiler body design allows a single storage space to accommodate boilers of different heating powers. Since the outer dimensions of the boiler body remain constant regardless of the coil configuration inside, the same storage facility can hold boilers designed for different heating applications, thereby reducing storage costs and space requirements.
3Power
If traditional boilers with varying coil diameters are manufactured, then different heating powers are achieved, but the assembly time and complexity increase
Solution Approach 1:
The universal boiler body design with standardized mounting features and opening positions enables rapid assembly for different heating power configurations. Workers can simply select the appropriate coil based on the desired heating power and install it in the pre-designed space, eliminating the need for complex customization or adaptation work. This significantly reduces assembly time and complexity while maintaining the ability to provide different heating powers.

Function Achieved in This Case
Enables the generation of multiple heating powers with reduced production costs and simplified assembly, allowing manufacturers to standardize production and quickly adapt to market needs while optimizing heating efficiency and emissions control.
Implementation Method 1
The water that flows through the latter is heated by the flame generated by the burner and/or by the smokes that generate in the boiler (or better, in a combustion chamber thereof which contains the coil and the burner) as a result of the operation of the burner

AI summary
A boiler for heating rooms and producing sanitary water, said boiler comprising a tubular cylindrical body or ferrule (26), end closing elements coupled with opposite ends of such body and a heat exchanger (2, 3) through which a fluid flows and placed inside the assembly formed of such body or ferrule (26) and end elements, internally to said heat exchanger (2, 3) a gas burner (21) being present, suitable for heating said fluid flowing through the heat exchanger (2, 3), at least one of said end elements comprising a frame (1) which said heat exchanger rests on. The frame (1) has a predetermined outer diameter (K) so as to define an end element with constant dimensions associated with a body also having a fixed outer diameter, the frame (1) co-operating alternatively with at least two heat exchangers (2, 3) having different heat exchanging surfaces.
