Beverage Container Lid Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beverage container lids lack effective insulation, suffer from excessive condensation, and have inadequate sealing and venting features, which affect the performance and usability of the containers.
Innovation Solution
The design incorporates a lid assembly with a rotational axis, helical threading, and a cover that provides thermal insulation through air pockets, improved sealing with a gasket, and venting apertures, allowing the lid to actuate between open and closed positions for fluid communication and sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a lid assembly is added to a beverage container, then sealing and insulation performance are improved, but device complexity increases
Solution Approach 1:
The lid assembly is divided into multiple functional components: a lid body with threading for attachment, a gasket for sealing, and a cover with insulation chambers. This segmentation allows each component to perform its specific function effectively while maintaining overall system reliability without excessive complexity.
Solution Approach 2:
The gasket is positioned within the lid body structure, and the cover with insulation chambers is nested over the lid body. This nesting arrangement integrates multiple functions (sealing, insulation, attachment) into a compact assembly, improving sealing performance without proportionally increasing complexity.
2Temperature
If insulation chambers are added to the cover, then thermal insulation is improved, but device complexity increases
Solution Approach 1:
The cover incorporates insulation chambers that create air-filled porous spaces between the inner and outer walls. These chambers trap air, which is a poor thermal conductor, thereby providing effective thermal insulation while maintaining a relatively simple overall cover structure.
Solution Approach 2:
The cover functions as a composite structure combining solid wall material with air-filled insulation chambers. This composite approach provides enhanced thermal insulation performance without requiring complex additional components, as the insulation is integrated into the cover's basic structure.
3Reliability
If a gasket is added to improve sealing, then sealing performance is improved, but ease of manufacture decreases
Solution Approach 1:
The gasket is combined with the lid body in an integrated assembly where the gasket is positioned within a groove or channel of the lid body. This merging of components ensures proper sealing performance while simplifying manufacturing, as the gasket and lid body can be assembled together in a single operation rather than requiring separate complex fastening procedures.
4Ease of operation
If helical threading is added for detachable engagement, then ease of operation is improved, but device complexity increases
Solution Approach 1:
Instead of adding complex locking mechanisms to secure the lid to the container, the design uses helical threading that relies on the natural screw-thread engagement principle. The threading is formed directly on the lid body, allowing simple rotational attachment and detachment without additional components, thus improving ease of operation while minimizing complexity.

AI summary
One or more beverage container lid assemblies are provided that is configured to enclose a beverage within a beverage container. The lid assemblies selectively actuate between closed and open positions. In the open position the beverage within the beverage container is accessible, and in the closed position the beverage is enclosed within the beverage container.
