Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid container lids fail to effectively enable liquid pooling and heat transfer from lid-compartmentalized liquid prior to liquid egression, leading to inefficiencies in cooling and potential leakage during consumption.
Innovation Solution
The development of a liquid container lid construction with a damming insert and specific sealing mechanisms that create a dual-seal interface between the lid and container, allowing for liquid pooling and heat transfer through a primary outlet, while maintaining a secure fit during thermal expansion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single-seal interface is used between lid and container, then the device complexity is reduced, but the reliability of sealing during thermal expansion deteriorates
Solution Approach 1:
The sealing interface is segmented into two distinct seals: a first seal between the container rim and lid, and a second seal between the container rim and the damming insert. This segmentation allows each seal to handle specific aspects of the thermal expansion problem, with the first seal maintaining overall lid attachment and the second seal preventing liquid leakage during expansion.
Solution Approach 2:
The damming insert acts as an intermediary element between the container and lid, creating a dual-seal system. This intermediary structure enables the first seal to maintain lid attachment while the second seal specifically addresses liquid containment during thermal expansion, resolving the contradiction between simplicity and reliability.
2Temperature
If liquid pooling compartmentalization is added to the lid, then cooling efficiency is improved, but the device complexity increases
Solution Approach 1:
The cooling compartmentalization function is merged with the sealing function by integrating the damming insert into the lid structure. The insert creates liquid pooling compartments that enhance cooling while simultaneously forming part of the dual-seal system, thus achieving cooling improvement without proportionally increasing overall device complexity.
Solution Approach 2:
The damming insert serves multiple functions: it creates liquid pooling compartments for enhanced cooling, forms a second seal to prevent leakage during thermal expansion, and structurally connects to the lid. This multi-functionality allows cooling efficiency improvement while minimizing the increase in device complexity.
3Reliability
If a secure fit during thermal expansion is maintained, then leakage prevention is improved, but the ease of manufacture deteriorates
Solution Approach 1:
Different sealing qualities are applied at different locations: the first seal uses a configuration optimized for maintaining lid attachment during thermal expansion, while the second seal uses a configuration specifically optimized for preventing liquid leakage. This local differentiation of sealing qualities achieves reliable leakage prevention while using straightforward manufacturing approaches for each seal type.

AI summary
A preferred low-profile liquid container lid assembly enables a user to outfit particularized liquid containers for enabling lid-based liquid-pooling or compartmentalization and heat transfer from lid-pooled or lid-compartmentalized liquid prior to liquid egression from a lid-outfitted liquid container prior to liquid consumption. All embodiments provide liquid re-directing or damming structures that operate to control the delivery of hot liquid for promoting heat loss from re-directed liquid flows. Certain structures cooperate with existing art to minimize leakage problems associated therewith. Other structures operate to particularly shape parceled liquid volumes for effecting rapid heat transfers therefrom. Still other structures harness material-philic properties of liquids for further effecting rapid heat transfers and liquid directional control mechanisms. Combinations of the various structural features here noted are also contemplated throughout the following specifications.
