Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heat storage apparatuses are inefficient in completing the crystallization of heat storage materials within a short time, which limits their application in scenarios like urban automobile idling stops where quick cold storage is needed.
Innovation Solution
A heat storage apparatus with a stirrer and a projection that continuously contacts the inner surface of the casing, generating pressure fluctuations to rapidly produce and diffuse crystalline nuclei throughout the heat storage material, facilitating rapid crystallization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If conventional heat storage apparatus designs are used, then the structure is simple, but the crystallization time is long
Solution Approach 1:
The stirrer is segmented into multiple functional components: a rotation body for stirring the heat storage material, and multiple projections extending from it that contact the casing inner surface. This segmentation allows each component to perform a specific function - the rotation body provides stirring while the projections generate pressure fluctuations - thereby reducing crystallization time without creating an overly complex integrated structure.
Solution Approach 2:
The projections act as an intermediary element between the stirrer and the casing. By contacting the casing inner surface during rotation, the projections transmit mechanical energy to generate pressure fluctuations in the heat storage material, which promotes rapid crystallization. This intermediary mechanism solves the contradiction by adding a simple intermediate component rather than fundamentally redesigning the entire system.
2Productivity
If the stirrer rotates without contacting the casing, then the structure is simple, but the pressure fluctuation is insufficient for rapid crystallization
Solution Approach 1:
The stirrer configuration is made dynamic through the rotating projections that periodically contact the casing inner surface. This dynamic interaction generates time-varying pressure fluctuations in the heat storage material, which are essential for rapid crystallization. The dynamic design allows the system to achieve high productivity while maintaining relatively simple structure, as the complexity is introduced only during operation rather than in the static configuration.
3Productivity
If multiple nucleation devices are added, then the crystallization efficiency improves, but the device complexity increases significantly
Solution Approach 1:
The stirrer is designed with multi-functionality, serving both as a stirring device and as a pressure fluctuation generator through its projections. This single multi-functional component replaces what would otherwise require separate nucleation devices, thereby improving crystallization efficiency while avoiding significant increases in device complexity. The projections enable the stirrer to perform multiple functions that would traditionally require additional dedicated components.
