Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid control devices face issues with uneven liquid spreading and unstable vaporization due to non-uniform contact between the mesh-like body and the heat storage plate, leading to difficulties in attaching and detaching the mesh-like body and maintaining its integrity during use.
Innovation Solution
A liquid control device design featuring a mesh-like body with first and second holders attached to its outer edge portions, supported by a moving member biased by a spring to ensure uniform contact with the liquid-supplied surface, along with a lid member for sealing, which stabilizes the mesh and improves workability and cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mesh is pushed against the upper surface of the heat storage plate by the tips of a plurality of pins disposed at a predetermined pitch, then the mesh can be attached to the heat storage plate, but the degree of intimate contact of the mesh with the upper surface of the heat storage plate differs between the portion pushed by the pin tip and the portion not pushed, resulting in uneven liquid spreading and unstable vaporization
Solution Approach 1:
The patent employs a moving member that can dynamically adjust the position of the mesh-like body to ensure uniform contact with the liquid-supplied surface. The moving member is biased by a biasing member (spring) to apply consistent force across the entire mesh surface, eliminating the non-uniform contact caused by fixed pin positions while maintaining easy attachability through the movable mechanism.
Solution Approach 2:
The patent changes the contact mechanism from discrete point contact (pin tips) to continuous surface contact by introducing a moving member that presses the entire lower surface of the mesh-like body uniformly against the liquid-supplied surface. This parameter change from localized to distributed contact ensures uniform liquid spreading and stable vaporization while maintaining ease of operation through the movable design.
2Reliability
If the mesh-like body is held in tension to prevent looseness, then uniform contact with the liquid-supplied surface is achieved, but the complexity of the attachment mechanism increases
Solution Approach 1:
The patent segments the attachment mechanism into modular components: holders attached to the outer edge portions of the mesh-like body, a moving member for positional adjustment, and a biasing member for applying tension. This segmentation allows each component to perform its specific function efficiently while keeping the overall system manageable and not excessively complex.
Solution Approach 2:
The patent introduces a moving member as an intermediary between the fixed structure and the mesh-like body. This intermediary component facilitates the transmission of biasing force uniformly across the mesh while allowing for easy attachment and detachment, thereby achieving uniform contact without proportionally increasing system complexity.
3Ease of operation
If the mesh-like body is made easily attachable and detachable, then workability is improved, but the mesh may become loose or damaged during use
Solution Approach 1:
The moving member provides a dynamic attachment mechanism that allows easy attachment and detachment while maintaining mesh integrity during use. The biasing member ensures continuous tension on the mesh-like body, preventing looseness during operation. The combination of movable attachment with biased tension resolution the contradiction between ease of operation and structural integrity.
4Reliability
If the mesh-like body is brought into intimate contact with the liquid-supplied surface uniformly, then liquid spreading and vaporization are stabilized, but the difficulty in attaching and detaching the mesh increases
Solution Approach 1:
The patent uses a dynamic moving member that can be easily positioned and locked, allowing uniform contact to be achieved without excessive attachment difficulty. The biasing member automatically maintains the mesh-like body in intimate contact with the liquid-supplied surface throughout operation, ensuring stable liquid spreading and vaporization while the movable design keeps attachment straightforward.
