Toggle-Based Beverage Lid Assembly for Circumferential Drinking Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable beverage container lids are complex and costly due to their reliance on spring-driven ratchet and tooth mechanisms, which complicate manufacturing and assembly, limiting user access to drink from multiple points along the lid's circumference.
Innovation Solution
A toggle mechanism-based lid assembly without biasing elements or ratchet mechanisms, featuring a valve and actuation element linked by a linkage element, allowing users to drink from any point on the lid's circumference while maintaining spill prevention, with a simpler design for easier and cheaper manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a spring-driven ratchet and tooth mechanism is used to allow drinking from multiple points along the lid's circumference, then user convenience is improved, but device complexity and manufacturing cost increase significantly
Solution Approach 1:
The patent removes the complex spring-driven ratchet and tooth mechanism from the lid assembly, retaining only the essential valve and actuation elements. This extraction of unnecessary components directly reduces device complexity while preserving the core functionality of allowing users to drink from multiple points along the circumference.
Solution Approach 2:
Instead of using a complex mechanism to enable multi-point drinking, the patent inverts the approach by designing a simple valve system that can be positioned at various locations around the lid's circumference. The simplicity of the valve and actuation element allows them to be distributed around the perimeter, providing multiple drinking access points without requiring complex interconnecting mechanisms.
2Ease of operation
If a spring-driven ratchet and tooth mechanism is used to achieve multi-point drinking access, then user convenience is improved, but manufacturing cost increases
Solution Approach 1:
By removing the expensive spring-driven ratchet and tooth mechanism, the patent significantly reduces manufacturing costs. The remaining components (valve, actuation element, housing) are simpler to manufacture and assemble, directly addressing the cost issue while maintaining the ability to drink from multiple points.
Solution Approach 2:
The patent employs simple, inexpensive valve and actuation element designs that can be easily manufactured and replaced if needed. These simplified components are far cheaper than complex spring-driven mechanisms, making the overall lid assembly more cost-effective while achieving the same user convenience.
3Adaptability or versatility
If a spring-driven ratchet and tooth mechanism is used to allow drinking from multiple points, then versatility is improved, but manufacturing complexity increases
Solution Approach 1:
The patent divides the lid assembly into multiple independent valve units, each with its own actuation element. These segmented valves can be positioned at different locations around the circumference, providing versatile drinking access without requiring a complex interconnected mechanism. Each valve-unit combination is simple and can be independently manufactured and assembled.
Solution Approach 2:
The patent designs a universal valve and actuation element assembly that can be replicated and positioned at multiple locations around the lid's circumference. This universal design provides versatility for drinking from any point while maintaining simplicity in each individual component, avoiding the need for complex specialized mechanisms.

AI summary
A portable beverage container includes a base adapted to contain a liquid and a lid assembly that is removably coupled to the base. The lid assembly is reconfigurable between an open position, whereby a user can drink the liquid from the base at any portion along the circumference of the top of the lid assembly, and a closed position, whereby the liquid is substantially prevented from exiting the base, such that the lid assembly prevents accidental spilling or splashing.
