Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional rollable water cups face challenges in heat preservation and portability, as they are often large and cumbersome, and lack effective heat retention and stability, leading to inconvenience and reduced lifespan due to water leakage.
Innovation Solution
A rollable heat preservation cup design featuring a two-layered cup body with a heat-preserving material layer between the inner and outer layers, a fixing ring, and a bottleneck that securely embeds the cup body, enhancing stability and heat retention through a multi-layered structure and secure fixation mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a large-sized cup body is designed to contain more water, then the water storage capacity is improved, but the portability and space occupation are worsened
Solution Approach 1:
The cup body is designed with dynamic flexibility, allowing it to be rolled up into a compact state for portability and expanded to a large capacity state for water storage. The flexible material enables the cup to transition between different volume states, resolving the contradiction between large water capacity and small portable volume.
2Ease of operation
If a soft material is used to enable the cup body to be rolled up, then the portability is improved, but the heat preservation capability is worsened
Solution Approach 1:
A vacuum insulation layer is nested between the inner cup body and outer cup body, creating a thermal barrier while maintaining the flexible, rollable structure. The multi-layer nested design provides heat preservation without compromising the soft material's ability to be rolled up for portability.
3Device complexity
If a single-layered cup body is used, then the device complexity is reduced, but the heat preservation and water leakage prevention are worsened
Solution Approach 1:
The cup adopts a nested multi-layered structure with inner cup body, vacuum insulation layer, and outer cup body. This nested design provides enhanced heat preservation and leakage prevention while maintaining relatively simple overall structure and manufacturing process.
4Reliability
If the upper end part of the cup body is firmly fixed, then the stability and reliability are improved, but the portability and rollability are worsened
Solution Approach 1:
The fixing structure is applied locally only to the upper end part of the cup body, where stability is needed, while the rest of the cup body remains flexible and rollable. This localized fixing approach maintains both stability during use and portability when needed.
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 multi-layered cup body significantly reduces heat transmission, prevents water leakage, and provides stable and reliable use, even under force, thereby improving user experience and product lifespan.
Implementation Method 1
A heat-preserving material layer is disposed between the inner-layer cup body and the outer-layer cup body
