Drink Bottle Lid Hinge and Spout Cover to Prevent Pinching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drink bottles with removable lids and spouts often suffer from breakage and inconvenience in use due to the design of the hinge and bail handle mechanisms, which can lead to pinching and difficulty in reattachment.
Innovation Solution
A beverage bottle design featuring a removable lid with an inner lid, a push-button mechanism, and a pivotable outer lid that can be locked and unlocked to cover the spout, along with a bail handle that can be easily deployed and stowed, all designed to resist breakage and facilitate reattachment, with a hinge structure that prevents finger pinching and a tunnel-enclosed locking mechanism for protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the lid components are made permanently fixed, then structural strength is improved, but ease of cleaning and maintenance deteriorates
Solution Approach 1:
The lid is divided into separable components including an outer lid, inner lid, and spout assembly that can be detached from one another. The hinge mechanism enables controlled separation while maintaining structural integrity during use. This segmentation allows each component to be individually cleaned or replaced without compromising the overall structural strength when assembled.
2Ease of repair
If the lid components are made easily removable, then ease of cleaning is improved, but reliability deteriorates
Solution Approach 1:
The hinge mechanism is pre-configured with interlocking features and engagement points that ensure components connect securely before use. The design includes predetermined attachment paths and alignment features that guide proper assembly, ensuring reliable reattachment after cleaning without requiring complex assembly procedures or compromising connection strength.
3Ease of operation
If the hinge structure includes open openings for movement, then ease of operation is improved, but harmful factors increase due to pinching risk
Solution Approach 1:
The hinge incorporates flexible sealing elements and thin film structures that cover moving openings while permitting necessary mechanical movement. These flexible barriers prevent fingers or foreign objects from entering hazardous zones during hinge operation, maintaining ease of operation while eliminating pinching risks through the use of compliant protective layers.
4Ease of operation
If the push button mechanism is exposed for easy access, then ease of operation is improved, but reliability deteriorates due to exposure to elements
Solution Approach 1:
The push button mechanism is nested within a protective housing or tunnel structure that is integrated into the lid assembly. This nested configuration allows the button to remain accessible for operation while being physically enclosed and protected from environmental elements such as moisture, dust, and contamination, thereby maintaining both ease of operation and reliability.

AI summary
A drink bottle with a removable lid includes an inner lid attached to the mouth of the bottle and an outer lid or cover pivotably mounted on said inner lid. A drink spout extends from the inner lid. The outer lid or cover may be locked into a closed position covering the drink spout. A push button release is activated to unlock the outer lid and permit the outer lid to pivot to a position exposing the drink spout for access by a user. The outer lid may be snapped of the inner lid by moving the outer lid beyond an open position. A bail handle on the outer lid is retained in a stowed position in a recess in the outer lid or is moved to a deployed position. The bail handle disconnects from the outer lid when moved beyond the deployed position. The push button for releasing the closed outer lid is enclosed within a tunnel in the inner lid.
