Rotatable Resilient Handle Bottle for Limited-Dexterity Drinking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users with limited or reduced dexterity face difficulties in drinking from conventional drinking bottles, often requiring assistance due to challenges in gripping and lifting the bottle, leading to reduced hydration, especially in scenarios like wearing large gloves.
Innovation Solution
A drinking bottle with a rotatable handle coupled to the container via a resilient material and a coupling mechanism, allowing limited rotation between two positions, enabling easy lifting and tilting without direct grip on the container, suitable for users with reduced dexterity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional drinking bottle is used, then the bottle structure is simple, but users with limited dexterity cannot easily grip and lift the bottle
Solution Approach 1:
The bottle is segmented into a container body and a separate handle assembly. The handle is rotatably coupled to the container via a coupling mechanism, allowing the gripping function to be separated from the container body. This enables users to grip the handle instead of the container, solving the dexterity problem while keeping the container structure relatively simple.
Solution Approach 2:
The handle is designed to be rotatable relative to the container through a coupling mechanism that permits rotation within a predetermined range. This dynamic configuration allows the handle to move between an extended position (for gripping) and a retracted position (for drinking), providing adaptability without requiring complex mechanisms.
2Strength
If the handle is made resilient to maintain shape, then the handle can support the bottle weight, but the handle material must be sufficiently strong
Solution Approach 1:
The handle is made from a resilient material with specific mechanical properties that allow it to maintain its shape while supporting the bottle weight. The material parameters (resilience, strength-to-weight ratio) are selected to enable the handle to function as both a gripping surface and a structural support element without requiring overly complex reinforcement.
3Ease of operation
If the handle rotation is limited by coupling mechanism, then the handle position is controlled, but the coupling mechanism adds complexity
Solution Approach 1:
The coupling mechanism provides controlled rotation of the handle relative to the container, permitting movement within a predetermined angular range while preventing full rotation. This dynamic control allows the handle to transition between extended and retracted positions automatically based on user manipulation, providing position control without requiring complex actuation systems.
4Ease of operation
If the handle extends above the container for gripping, then the user can easily grip the handle, but the handle must be long enough to provide leverage
Solution Approach 1:
The handle length and rotation range are designed to provide sufficient leverage for lifting and tilting the bottle. The coupling mechanism allows the handle to extend above the container during the lifting phase, then rotate to a retracted position during the drinking phase, optimizing both grip accessibility and mechanical advantage without requiring the handle to remain extended throughout.

Function Achieved in This Case
Enables independent drinking by users with limited dexterity, facilitating hydration without needing assistance, even when wearing large gloves, through a handle that maintains its shape and orientation relative to the bottle.
Implementation Method 1
the handle is formed of a resilient material and is arranged to substantially maintain its shape during use so that the container depends from a distal end thereof

AI summary
A drinking bottle, a drinking system and a method of drinking are provided. The drinking bottle comprises: a container for containing liquid therein; a handle for lifting the container; and a coupling mechanism rotatably coupling the handle to the container; wherein the coupling mechanism is arranged to provide limited rotation of the handle relative to the container between a first position in which the handle extends above the container, and a second position in which the handle is rotated to extend out to the side of the container; and wherein the handle is formed of a resilient material and is arranged to substantially maintain its shape during use so that the container depends from a distal end thereof.
