Solution Overview

Problem

Existing container lids face challenges in providing a secure, air-tight seal while also being easy to open and close, often requiring a trade-off between leakage prevention and user convenience.

Innovation Solution

A container lid design featuring a push button with a latch mechanism and a bias member that selectively engages and disengages from the container top, allowing for easy operation and a secure seal through a combination of friction, interference, and a resilient member to maintain the closure position.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a latch mechanism is used to secure the closure, then the seal reliability is improved, but the device complexity increases

Engineering Contradiction:
Improveseal reliabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The latch mechanism is divided into separate functional components: a latch member with engagement and disengagement positions, a push button for actuation, and a bias member for automatic resetting. This segmentation allows each component to perform its specific function efficiently while maintaining overall system reliability without excessive complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The latch mechanism transitions from a static locked position to a dynamic state where it can be easily switched between engaged and disengaged positions through push button actuation. The bias member provides automatic dynamic resetting to the engaged position, ensuring reliable sealing while allowing quick opening when needed.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If a push button with latch mechanism is implemented, then the ease of operation is improved, but the device complexity increases

Engineering Contradiction:
Improveease of operationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The bias member automatically returns the latch mechanism to the engaged position after opening, eliminating the need for manual resetting. The system serves itself by automatically re-latching when the push button is released, improving ease of operation while keeping the mechanism simple.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The push button combines multiple functions: it actuates the latch to disengage, allows the closure to open, and when released, triggers the automatic resetting through the bias member. This merging of functions into a single simple component improves ease of operation without proportionally increasing complexity.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If the push button is substantially enclosed by the closure, then the reliability is improved, but the ease of operation may be worsened

Engineering Contradiction:
ImprovereliabilityVSAvoidease of operation
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The closure structure provides substantial enclosure of the push button mechanism to protect it, but includes a strategically positioned access region that allows easy reaching and actuation. This local differentiation ensures both reliability through protection and ease of operation through accessible positioning.

Inventive Principle:
Principle #3Local quality

AI summary

A container lid including a container top and a closure coupled to the container top. The container top defines a lid opening. The closure is rotatable about a closure rotation axis between a closed position in which the lid opening is closed and an open position in which the lid opening is open. The closure has a proximal end positioned at the closure rotation axis and a distal end positioned away from the axis. A push button is movably coupled to the closure and is movable between first and second push button positions. In the first push button position, the closure is retained in the closed position. In the second push button position, the closure is not retained in the closed position. The push button is positioned at the proximal end of the closure. The push button is rotatable about the closure rotation axis.
