Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slushy cups with integrated designs are prone to slipping and leakage, and soft material cups can contaminate drinks due to refrigeration fluid mixing and rim deformation during hand squeezing.
Innovation Solution
A detachable slushy maker cup with a hard sealing connection assembly between a soft outer cup body and inner core, featuring a sealing connection assembly with interference fits and threaded connections to prevent leakage and deformation, along with a convex rib structure for enhanced support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If an integrated design is used for the cup core and cup shell, then the structure is simple, but the cup body easily slips out of hands and the refrigerating fluid leaks
Solution Approach 1:
The cup body is divided into separate components: an inner cup core and an outer cup shell, connected through a sealing connection assembly. This segmentation allows the sealing connection assembly to be specifically designed for reliable connection and sealing, while maintaining overall structural simplicity.
2Ease of operation
If soft material is used for the outer cup body, then hand squeezing is enabled, but the cup rim deforms and drink overflows
Solution Approach 1:
Different parts of the cup structure have different material properties: the outer cup body uses soft material for flexibility and hand squeezing, while the sealing connection assembly and cup rim use hard materials to maintain structural stability and prevent deformation during operation.
3Temperature
If soft packaging is used for the refrigeration bag, then quick cooling is achieved, but the refrigeration fluid mixes with the drink
Solution Approach 1:
The sealing connection assembly acts as an intermediary barrier between the refrigerating fluid and the drink. It includes sealing rings that prevent the refrigerating fluid from the outer cup body from mixing with the drink in the inner cup core, while still allowing thermal energy transfer for cooling.
4Reliability
If a hard sealing connection assembly is used, then stable sealing is achieved, but the device complexity increases
Solution Approach 1:
The sealing connection assembly merges multiple functions into a single integrated component: it provides structural connection between the inner cup core and outer cup shell, ensures sealing through integrated sealing rings, and maintains positioning. This reduces the number of separate components while achieving reliable sealing.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution ensures a stable and sealed connection, preventing refrigeration fluid from mixing with drinks and maintaining cup integrity during use, while allowing efficient cooling and easy cleaning.
Implementation Method 1
the upper ring edge is in interference fit and sealed connection to the first annular groove; the flared ring edge enters the inside of the outer cup body from a top opening of the outer cup body and is in interference fit and sealed connection to the fourth annular groove
Implementation Method 2
the drinks in the inner core exchanges cold and heat with the refrigerating fluid in the outer cup body, and the temperature of the drinks in the inner core drops sharply
