Twist Lid Beverage Container Damping Lock Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beverage container lids lack an efficient and user-friendly unlatching mechanism that ensures secure closure and easy access, often requiring complex operations or compromising on sealing integrity.
Innovation Solution
A lid assembly featuring a twist ring with a damping member and a lock mechanism, allowing for easy rotation and secure latching/unlatching, with a damping member biasing the twist ring to its normal position for secure closure and user-friendly operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a twist ring mechanism is added to enable rotation for latching/unlatching, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The twist ring is rotationally connected around a portion of the lid base and integrates multiple functions including latching, unlatching, and sealing within a single component structure, reducing overall device complexity while maintaining ease of operation
Solution Approach 2:
The twist ring serves multiple purposes: it acts as a rotational mechanism for latching/unlatching, provides a grip for user operation, and works with the damping member to maintain secure closure, consolidating several functions into one component
2Reliability
If a damping member is added to maintain the twist ring in normal position, then reliability of secure closure is improved, but device complexity increases
Solution Approach 1:
The damping member automatically biases the twist ring to its normal position without requiring external intervention or complex control systems, providing self-regulating secure closure that maintains reliability while adding minimal complexity
Solution Approach 2:
The damping member acts as a counterbalancing element that offsets forces attempting to displace the twist ring from its normal position, ensuring reliable return to the closed state through a simple mechanical biasing mechanism
3Reliability
If a lock mechanism is added to prevent rotation when locked, then security of closure is improved, but ease of operation worsens
Solution Approach 1:
The lock mechanism transitions between locked and unlocked states through the rotational motion of the twist ring itself, using the same user operation to both secure and release the closure rather than requiring separate operations
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 mechanism provides a secure seal when closed and easy access when open, enhancing user convenience and durability by utilizing a damping member to maintain the twist ring in its normal position for secure closure.
Implementation Method 1
a damping member between a portion of the lid base and the twist ring, the damping member adapted to stop rotation of the twist ring and to bias the twist ring in an opposite direction

AI summary
A lid for a beverage container includes a lid cover, a lid base and a twist ring. The twist ring is rotationally secured to the lid base. The lid cover has a first latch member, the lid base has a first mating member, and the twist ring has a second latch member that mates with the first latch member and a second mating member that mates with the first mating member to allow the twist ring to rotate with respect to the lid base to disengage the second latch member from the first latch member.
