Solution Overview
Problem
Conventional drinking vessels lack a convenient and reliable mechanism for storing and retrieving a lid that prevents spillage and maintains the temperature of beverages, often resulting in lid loss or inefficient temperature retention.
Innovation Solution
A drinking vessel design that incorporates a cup and bottle with a lid that is elastically deformable, allowing it to reversibly engage with the cup and bottle, featuring a storage recess for the lid, which ensures secure retention and easy retrieval, and a configuration that allows the cup to overlie the bottle for enhanced thermal insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a lid is provided for the cup to prevent spillage and maintain temperature, then beverage protection is improved, but the lid may be lost or misplaced
Solution Approach 1:
The lid storage recess is integrated into the cup structure itself, with the recess formed by the cup base and recess wall. The lid nests within this recess when not in use, eliminating the need for separate storage containers or attachments.
Solution Approach 2:
The elastically deformable lid automatically engages with the cup wall free edge when inserted, and the recess structure automatically retains the lid through elastic deformation and geometric constraints, requiring no additional fastening mechanisms or user intervention for secure storage.
2Ease of operation
If the lid is made elastically deformable for easy engagement and storage, then ease of operation is improved, but structural complexity increases
Solution Approach 1:
The lid is constructed from an elastically deformable material that allows it to flex and conform during engagement with the cup. This flexibility enables the lid to be compressed for insertion into the recess and to automatically seal against the cup wall free edge without requiring complex mechanical fasteners or adjustment mechanisms.
3Temperature
If the cup is designed to overlie the bottle for thermal insulation, then temperature retention is improved, but the device complexity increases
Solution Approach 1:
The cup is designed to fit over the bottle in a nested configuration, with the cup base resting on the bottle base and the cup wall surrounding the bottle. This nesting arrangement creates an insulating air gap between the beverage container and the external environment, reducing heat transfer while maintaining a simple two-component structure.
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 effectively prevents spillage, maintains beverage temperature, and reduces lid loss through a simple and reliable mechanism, providing a comprehensive solution for storing and drinking beverages while ensuring thermal insulation.
Implementation Method 1
the cup lid is at least partially elastically deformable, and insertion and removal of the cup lid into/out of the lid storage recess requires elastic deformation of the at least part of the cup lid
Implementation Method 2
The cup is configured so that it can reversibly overlie the bottle base and at least a portion of the outer face of the lower portion of the bottle with the inner face of the cup wall in contact with or in close proximity to the outer face of the lower portion of the bottle

AI summary
A drinking vessel comprises a bottle, a cup, and a cup lid. The bottle has a bottle base, a bottle mouth, and a bottle wall extending between the bottle base and the bottle mouth, the cup comprises a cup base, a cup mouth, and a cup wall, a first face of the cup base and an inner face of the cup wall define a cup volume, the cup volume is suitable for holding a potable beverage, and the inner face of the cup wall extends from the cup base to a free edge of the cup wall which defines the cup mouth. The cup lid is configured to reversibly engage with one or both of the free edge of the cup wall and the portion of the cup wall adjacent the free edge, and the cup lid is configured to close the cup mouth. The cup base and cup wall are so configured that the bottle base and at least a portion of bottle wall fit into the cup volume with the inner face of the cup wall in close proximity to the portion of a bottle wall. The cup further comprises a lid storage recess in which the lid storage recess is defined by a second face of the cup base and an inner face of a recess wall, the second face of the cup base faces away from the cup volume, and the inner face of the recess wall extends from the second face of the cup base away from the cup volume to a recess wall free edge, the recess wall free edge defines a recess mouth. The cup lid comprises a cup wall engaging means, and drinking aperture, and the cup lid and lid storage recess are so configured that the cup lid reversibly engages with the cup lid storage recess so that the cup lid is reversibly retained in the lid storage recess.
