Bottle-Shaped Container Asymmetric Grip Recesses for Stable Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bottle designs with side grips may not be comfortable or easy to use, leading to potential loss of control and risk of spillage or damage, especially when filled with liquids.
Innovation Solution
A bottle design featuring symmetrically positioned recesses on the side walls, with one recess sized for the thumb and the other for up to four fingers, aligned at the center, providing a ergonomic grip configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a side grip is formed by rectangular recesses on the rear portion of each side wall, then the container can be lifted and handled, but the grip may not always be comfortable and easy to use depending on container fill and user characteristics
Solution Approach 1:
The patent applies asymmetry by creating recesses of different sizes on opposite sides of the container. One recess is larger to accommodate fingers while the other is smaller for the thumb, matching the natural asymmetric configuration of a human hand. This asymmetric design improves grip comfort and adaptability across different user characteristics and container fills.
Solution Approach 2:
The patent applies local quality by providing different recess configurations at different locations on the container body. The larger recess is positioned for finger placement while the smaller recess is positioned for thumb placement, creating localized functional zones that optimize the overall gripping experience.
2Reliability
If the container is grasped in areas not adapted for gripping, then the user may lose control and drop the container, but this causes damage to the container and spillage of contents
Solution Approach 1:
The asymmetric recess design guides users to grasp the container in the correct orientation by providing distinct tactile feedback through the differently sized recesses. This prevents improper gripping that would lead to loss of control, container damage, or spillage.
Solution Approach 2:
The recess configuration is designed to be self-guiding, where the natural fit of the hand against the asymmetric recesses automatically positions the container correctly for safe handling, eliminating the need for user instruction or awareness.

AI summary
A bottle-shaped container including a neck portion, a body portion, a first recess having a first longitudinal length, and a second recess having a second longitudinal length. A center of the first longitudinal length is aligned with a center of the second longitudinal length. The recesses of the side walls together defining a side grip to allow a user to grasp the container. One side wall is for a thumb of the user, and the other side wall is for up to four fingers, which exclude the thumb, to grasp the bottle in the way that lends itself to the shape of the bottle.
