Solution Overview

Problem

Existing spill-proof containers for children are prone to overflow and bulkiness, and traditional lids are noisy and fail to return to an upright position after being knocked over.

Innovation Solution

A portable drinking container with a weighted, rounded base and a cylindrical body that automatically returns to an upright position, featuring a thermally insulating layer, a sealing valve, and a removable lid assembly with a straw nozzle.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If an inner and outer cup design is used to prevent spills, then spill prevention is improved, but the container becomes bulky and holds inadequate liquid volume

Engineering Contradiction:
Improvespill preventionVSAvoidliquid capacity
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The container is divided into two functional segments: a rigid outer cup body for structural support and a flexible inner bladder for liquid containment. This segmentation allows the outer cup to be smaller and less bulky while the inner bladder provides spill-proof containment through its flexibility and seal mechanism.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The inner bladder is made of flexible material that can deform and seal, changing the physical state from rigid to flexible containment. This parameter change enables the bladder to conform to the outer cup and create a spill-proof seal without requiring a bulky rigid structure.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If an air tight lid assembly is used to prevent spills, then spill prevention is improved, but the container creates noise when placed onto a surface

Engineering Contradiction:
Improvespill preventionVSAvoidnoise
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The sealing function is extracted from the lid assembly and transferred to the flexible inner bladder that contacts the outer cup body. The lid assembly only needs to seal the bladder opening, eliminating the need for a bulky, noisy air-tight lid mechanism while maintaining spill prevention.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The inner bladder acts as a flexible shell that provides the primary seal against the outer cup body. This flexible membrane creates an effective spill-proof barrier without requiring a rigid, noisy lid assembly, as the bladder itself conforms and seals.

Inventive Principle:
Principle #30Flexible shells and thin films

3Stability of the object's composition

If traditional rigid containers are used, then structural stability is maintained, but the container does not automatically return to upright position when knocked over

Engineering Contradiction:
Improvestructural stabilityVSAvoidself-righting capability
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The container transitions from a static rigid structure to a dynamic system where the flexible inner bladder can deform and shift. When knocked over, the liquid and bladder movement creates a restoring force that helps the container return to its upright position, combining structural stability with self-righting capability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The container incorporates flexible material parameters that allow deformation and movement of the inner bladder. This flexibility enables the container to dynamically respond to external forces and automatically return to upright position while maintaining overall structural integrity through the rigid outer cup.

Inventive Principle:
Principle #35Parameter changes

AI summary

A portable drinking bottle having a tapered cylindrical body terminating in a rounded base with a lid assembly. The rounded base is weighted in such a manner that it creates a bobble effect upon impact and will revert to the upright position which prevents spillage. The rounded base also provides a distinctive ergonomic form as well as while the lid assembly further facilitates spill-resistant drinking and ease of transport.
