Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Instantaneous heating apparatuses face frequent deformation of heating passages, leading to local overheating and water splashing, which can cause user accidents like burns during water discharge.
Innovation Solution
The apparatus includes a passage forming member and a close-pressing part with a pressing member to securely form a heating passage between the heating part and the passage forming member, reducing deformation and overheating, and utilizing a silicon passage forming member with a spiral groove to maintain a stable heating passage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the heating passage is formed by combining various members in a fitting fashion to increase heating time and prevent local overheating, then the heating effectiveness is improved, but the heating passage deforms frequently during formation and use, leading to local overheating and water splashing
Solution Approach 1:
The heating passage is formed by nesting the passage forming member inside the heating part, creating a concentric structure where the passage forming member fits within the heating part to define the heating passage space. This nested configuration improves structural stability while preventing deformation during formation and use.
Solution Approach 2:
The discharge member acts as an intermediary component that connects the heating passage to the external environment. It is inserted through the passage forming member and heating part, providing structural support and sealing functionality that prevents deformation and maintains heating passage integrity.
2Temperature
If the heating passage has a predetermined volume to prevent local overheating, then water heating uniformity is improved, but the heating passage deforms and loses its predetermined volume, causing local overheating
Solution Approach 1:
The passage forming member is nested inside the heating part to precisely define and maintain the heating passage volume. This nested structure ensures the heating passage retains its predetermined volume during formation and use, preventing deformation that would cause local overheating.
Solution Approach 2:
The heating passage is pre-formed with a predetermined volume and shape before water heating occurs. The passage forming member is pre-positioned inside the heating part to establish the correct geometric configuration, ensuring uniform water heating from the beginning of operation.
3Manufacturing precision
If the heating passage is formed by inserting one member inside another member, then the heating passage maintains predetermined volume and prevents local overheating, but the heating passage deforms during formation and use
Solution Approach 1:
The discharge member serves as an intermediary structural element that is inserted through the passage forming member and heating part. This intermediary component provides reinforcement and sealing, preventing deformation of the heating passage while maintaining the predetermined volume established by the nested structure.
Solution Approach 2:
The multi-level nested structure consisting of the passage forming member inside the heating part, with the discharge member passing through both, creates a reinforced configuration. This nested arrangement with multiple interacting members improves deformation resistance while maintaining precise volume control.
