Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drinking vessel lids with removable sealing mechanisms often face difficulties in installation, inadequate insulation of heated liquids, and contamination risks due to design obstructions at the drinking aperture.
Innovation Solution
A one-handed cam lid assembly with a removable sealing element, featuring a rotatable attachment collar and elastic sealing mechanism, which facilitates easy installation, effective insulation, and protection from contamination by allowing easy cleaning and alignment with the drinking aperture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If a removable sealing mechanism is provided for separate cleaning, then ease of cleaning is improved, but installation difficulty increases
Solution Approach 1:
The sealing mechanism is divided into separate components: a sealing element and a retaining housing that can be detached from each other. This segmentation allows the sealing element to be removed for cleaning while the retaining housing remains with the lid assembly, resolving the contradiction between ease of cleaning and installation difficulty.
Solution Approach 2:
The sealing element is extracted as a removable component from the lid assembly, allowing it to be separately cleaned. The retention mechanism includes features like an elastic member and cam action that enable easy insertion and removal of the sealing element without complex tools or procedures.
2Temperature
If insulation is provided for heated liquid, then heat retention is improved, but flow obstruction increases
Solution Approach 1:
Insulation is provided locally at the drinking aperture area where heat retention is most needed, rather than throughout the entire lid. The sealing element includes an insulating portion positioned at the aperture, while the cam mechanism and other functional areas remain unobstructed, allowing heat retention without flow obstruction.
Solution Approach 2:
The insulating portion is positioned vertically at the drinking aperture, extending into the opening without horizontally blocking the liquid flow path. This dimensional arrangement allows the insulation to retain heat while leaving the horizontal flow path clear for liquid to pass through to the user.
3Reliability
If the sealing element obstructs the flow, then sealing effectiveness is improved, but liquid flow to aperture is reduced
Solution Approach 1:
The sealing element includes a flexible lip or flange that can deform under liquid pressure. This flexible component maintains contact with the lid surface for effective sealing when the vessel is stationary, but yields to allow liquid flow when pressure is applied during drinking, resolving the contradiction between sealing effectiveness and liquid flow.
Solution Approach 2:
The sealing element transitions from a static sealing position to a dynamic state during use. The cam mechanism holds the sealing element in a sealed position during storage and transport, but allows it to move or deform when liquid flow is required, enabling both effective sealing and adequate liquid flow to the aperture.

AI summary
A lid assembly is provided comprising a lid main body and a lid valve subassembly removably attachable to the lid main body. The lid main body includes an upper portion having a drinking aperture and a first attachment element positioned below the upper portion in a lid cavity. The lid valve subassembly includes a subassembly main body, a sealing member, and an attachment collar rotatably attached to the subassembly main body. The attachment collar may be rotatable about an axis of rotation relative to the subassembly main body to selectively transition the lid assembly between an integrated configuration with the lid valve subassembly secured to the lid main body and a cleaning configuration with the lid valve subassembly separated from the lid main body. A second attachment element on the lid valve subassembly may engage with the first attachment element to releasable secure the lid assembly in the integrated configuration.
