Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional soup cups suffer from poor sealing properties, leading to soup leakage and safety hazards due to aging and deformation of plastic or rubber materials used in the cover and cover edge, especially under high temperatures or long-term use.
Innovation Solution
A soup cup design featuring a cup body with a compartment, an upper cover with a vertical wall and sealing rubber film, an oil seal spring, a sealing device, and a return device, along with a thermostatic device for heat insulation, which provides multiple layers of sealing to prevent leakage and maintain heat retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If plastic or rubber materials are used for manufacturing the cover and cover edge, then the sealing design is improved, but the cover is prone to aging and deformation after high temperature or long-term use
Solution Approach 1:
The sealing system is divided into multiple independent sealing components: a sealing ring at the cover edge and a sealing film at the bottom of the cover. This segmentation allows each component to be optimized separately and replaced independently if needed, improving overall reliability without compromising service life.
Solution Approach 2:
The patent uses different materials for different sealing components - the sealing ring is made of elastic material (rubber or silicone) while the sealing film is made of heat-resistant material. This composite material approach allows each component to perform its specific function optimally, with the heat-resistant film preventing degradation from high temperatures.
2Device complexity
If the cover and cup body are simply engaged, then the device complexity is reduced, but soup leakage occurs during movement or storage
Solution Approach 1:
The sealing ring and sealing film are pre-installed on the cover and cup body respectively before use. The sealing ring is fitted on the cover edge and the sealing film is attached to the bottom of the cover, so that when the cover is engaged with the cup body, sealing is immediately effective without requiring additional actions.
Solution Approach 2:
The patent employs a flexible sealing ring made of elastic material that can deform to conform to the cup body opening, and a heat-resistant sealing film at the bottom of the cover. These flexible elements ensure reliable sealing even with simple engagement, preventing leakage during movement or storage.
3Reliability
If the sealing rubber film is made tight against the cup body, then the sealing property is improved, but heat loss and liquid overflow occur due to gaps when attachment is unfirm
Solution Approach 1:
The sealing film is designed to be dynamically adjustable in its sealing pressure. During normal use, the sealing film maintains firm contact with the cup body to prevent heat loss and leakage. When the cover is opened or closed, the sealing film can flex and adjust its position, allowing for firm attachment during storage and transport while accommodating the opening/closing movements without creating harmful gaps.
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 design achieves primary, secondary, and tertiary sealing, preventing unfirm attachment and heat loss, ensuring a high heat retention effect and user safety by maintaining the soup's temperature and preventing liquid overflow.
Implementation Method 1
the oil seal spring expands to drive the sealing rubber film to deform, so as to be closely attached to the inner wall of the cup body to achieve tertiary sealing
Implementation Method 2
a thermostatic device arranged in the cup body and configured to reduce heat transfer of the soup stored in the compartment

AI summary
The present disclosure relates to a soup cup for maintaining a high sealing property. The soup cup includes a cup body; a compartment; an upper cover; a vertical wall; and an oil seal spring. When the upper cover is clamped to the cup body, primary sealing of the soup in the cup body can be completed, and then the sealing rubber film at the bottom of the upper cover can perform secondary sealing on the cup body; and moreover, the oil seal spring is embedded inside the sealing rubber film, and the oil seal spring expands to achieve tertiary sealing, thereby effectively preventing unfirm attachment between the upper cover and the cup body from caused by excessively long time, eliminating heat loss and liquid overflow caused by existence of various gaps, maintaining a high heat retention effect, and simultaneously creating a desirable use feeling for a holder.
