Thermos Cup Lid Segmentation for Quick Opening and Thorough Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional thermos cups have inconvenient lid operation and difficulty in cleaning the interior of the cup lid, leading to bacterial accumulation due to the threaded connection and inability to disassemble.
Innovation Solution
A cup design featuring a cup body with a connecting piece and a cup lid composed of an inner layer cylinder, sandwich cylinder, outer layer cylinder, first sealing ring, and sealing cap, allowing for easy opening and closing by rotating at a small angle and facilitating cleaning by detachable components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cup lid and cup body are connected by threads, then the connection is secure and reliable, but the operation becomes inconvenient requiring several rotations to open or close
Solution Approach 1:
The cup lid structure is segmented into multiple functional components: an outer layer cylinder for connection, a sandwich cylinder with sealing function, and an inner layer cylinder. This segmentation allows the connecting piece to engage with the connecting groove for reliable connection while the sealing cap can be independently rotated for quick opening/closing operation.
Solution Approach 2:
The patent introduces a dynamic sealing mechanism where the sealing cap can rotate relative to the sandwich cylinder. The sealing ring moves dynamically between compressed and relaxed states during opening/closing operations, enabling quick action without multiple rotations while maintaining connection reliability through the connecting piece and groove.
2Ease of manufacture
If the cup lid is designed as a unified structure, then the manufacturing is simple, but the interior cannot be cleaned thoroughly as it accumulates water and becomes a breeding ground for bacteria
Solution Approach 1:
The cup lid is divided into separable components including the sandwich cylinder, sealing cap, and inner layer cylinder. The sealing cap can be detached from the sandwich cylinder, allowing the interior surfaces to be accessed and cleaned thoroughly while preventing bacterial accumulation.
Solution Approach 2:
The sealing cap is extracted as a detachable component from the unified cup lid structure. This allows the interior of the sandwich cylinder to be emptied and cleaned, removing the water accumulation problem while maintaining the overall manufacturing simplicity through modular assembly.
3Ease of operation
If the cup lid components are made detachable for cleaning, then the cleaning convenience is improved, but the device complexity increases
Solution Approach 1:
The cup lid is segmented into a small number of essential components (sandwich cylinder, sealing cap, inner layer cylinder) that can be detached for cleaning. This limited segmentation provides cleaning convenience while avoiding excessive structural complexity.
Solution Approach 2:
The components are arranged in a nested configuration where the inner layer cylinder is placed within the sandwich cylinder, which is within the outer layer cylinder. This nesting arrangement simplifies the overall structure while allowing easy detachment of the sealing cap for cleaning purposes.
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
Enables effortless operation of the cup lid and thorough cleaning, preventing bacterial growth while enhancing the sealing of the cup lid when closed.
Implementation Method 1
a first sealing ring with elasticity sleeved on the lower portion of the sandwich cylinder... the sandwich cylinder drives the first sealing ring to move upward and squeezes the first sealing ring to bulge outward, and the first sealing ring is tightly attached to the inner wall of the cup body
