Cap and water-heating device including the same
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water-heating devices are inefficiently manufactured for either indoor or outdoor use, leading to malfunctions when installed in inappropriate environments and inefficient production and inventory management.
Innovation Solution
A cap with an exhaust duct made of high-heat-resistant material is designed to convert an indoor water-heating device for outdoor use, featuring an exhaust hole and air supply hole to facilitate air introduction and gas release, preventing foreign matter and ensuring compatibility with different installation environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If water-heating devices are separately manufactured for indoor use and outdoor use, then the device can be optimized for specific installation environments, but it leads to inefficient production and inventory management
Solution Approach 1:
The patent applies universality by designing a single water-heating device that can function in both indoor and outdoor environments through interchangeable caps. The device body remains universal while the cap adapts to different installation locations, eliminating the need for separate indoor and outdoor models and improving production efficiency.
Solution Approach 2:
The patent segments the water-heating device into a universal body and environment-specific caps. The cap is separated as an independent component that can be swapped depending on whether the device is installed indoors or outdoors, allowing the main device to be manufactured once while adapting to different environments through component interchangeability.
2Reliability
If an outdoor water-heating device is installed indoors, then the device structure is suitable for outdoor environment, but it becomes difficult to supply air and release exhaust gas
Solution Approach 1:
The patent applies dynamics by making the cap interchangeable rather than fixed. The cap can be dynamically changed from an indoor type to an outdoor type depending on the installation environment, allowing the device to adapt its air supply and exhaust characteristics to match the required environment rather than being static in its design.
3Reliability
If an indoor water-heating device is installed outdoors, then the device is designed for indoor use, but foreign matter is introduced through connecting adaptor, air supply tube, or exhaust tube causing malfunctions
Solution Approach 1:
The patent applies local quality by designing the cap with location-specific protective features. The outdoor cap includes structures specifically tailored for outdoor protection such as shields against foreign matter, while the indoor cap has features optimized for indoor environments. Each cap's local structure is optimized for its specific installation environment, preventing foreign matter intrusion in outdoor installations.
4Reliability
If the exhaust duct is made of material with higher heat resistance than the cover, then the exhaust duct can withstand high-temperature exhaust gas, but the device requires multiple material types increasing complexity
Solution Approach 1:
The patent applies local quality by using different materials in different locations where needed. The exhaust duct uses high-heat-resistant material only in the portion exposed to exhaust gas, while other parts of the device can use standard materials. This localized material selection provides necessary heat resistance without requiring all components to be made from high-temperature materials, thus controlling overall complexity.

Function Achieved in This Case
Enables a single water-heating device to be installed both indoors and outdoors, improving functionality and inventory management by preventing malfunctions and maintaining product integrity across environments.
Implementation Method 1
an exhaust duct that is received in the receiving space and coupled to the cover and that forms an exhaust channel that connects an exhaust tube included in the case and the exhaust hole and releases the exhaust gas, in which the exhaust duct is formed of a material different from a material of the cover, and the material of the exhaust duct has higher heat resistance than the material of the cover

AI summary
The present disclosure provides a cap and a water-heating device having the same. The cap for covering a top side of a case of the water-heating device includes a cover having a receiving space that is open at the bottom, the cover including an exhaust hole formed therein for releasing exhaust gas in the case to the outside, and an exhaust duct that is received in the receiving space and coupled to the cover and that forms an exhaust channel that connects an exhaust tube included in the case and the exhaust hole and releases the exhaust gas, in which the exhaust duct is formed of a material different from a material of the cover, and the material of the exhaust duct has higher heat resistance than the material of the cover.
