Curved Plate Bottle Handle for Grip Strength at Lower Weight
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bottles with handles face difficulty in maintaining grip strength while reducing the weight of the handle by narrowing or thinning the holding portion.
Innovation Solution
The handle is designed with a curved, plate-shaped holding portion that projects forward in vertical and orthogonal cross-sections, featuring side plate portions protruding outward and constricted inward sections to enhance grip comfort and reduce weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the width of the holding portion is narrowed or the thickness is thinned to reduce handle weight, then the weight of the handle is reduced, but it becomes difficult to hold the holding portion
Solution Approach 1:
The holding portion is designed with a curved surface that projects forward, creating an ergonomic shape that naturally guides finger placement. This curvature allows the fingers to align with the front surface of the holding portion, improving grip comfort and ease of holding even when the overall dimensions are reduced for weight savings
Solution Approach 2:
The holding portion features a plate shape with specific curvature characteristics that concentrate grip-enhancing geometry at the gripping surface while maintaining thinner sections elsewhere. This localized quality optimization allows the critical gripping area to provide excellent finger alignment and comfort without requiring the entire handle to be thick or heavy
2Weight of moving object
If the holding portion is made thinner to reduce weight, then the weight is reduced, but the structural strength may be compromised
Solution Approach 1:
The curved surface design of the holding portion creates a more efficient stress distribution pattern compared to flat or angular designs. The curvature helps distribute applied forces more evenly across the plate structure, enhancing structural strength while allowing for reduced material thickness and weight
Solution Approach 2:
The holding portion utilizes a plate shape configuration that functions as a thin-walled structure optimized for strength-to-weight ratio. The plate geometry with curved surfaces provides adequate structural strength for handling purposes while maintaining minimal thickness to reduce overall handle weight

AI summary
The present invention provides a bottle with a handle in which a handle is attached to a body portion of a bottle having a center axis line extending in an upward-downward direction. The handle includes a fixed portion, a holding portion, an upper joint portion, and a lower joint portion. The holding portion is formed in a plate shape, front and rear surfaces of the holding portion being directed in a forward-rearward direction. The holding portion is curved so as to exhibit a curved shape projecting forward in a vertical cross-sectional view in the upward-downward direction and exhibit a curved shape projecting forward in a cross-sectional view orthogonal to the upward-downward direction.
