Integrally Molded Handle on Packaging Container
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging containers with handles are complex and labor-intensive to manufacture due to the need for separate production and assembly of the container body and handle.
Innovation Solution
A one-piece packaging container design where the handle is molded onto the container body using a deep-drawing process, with the handle articulated via a film hinge, allowing for easy folding and secure attachment, and optionally featuring a connecting device and grip surface for enhanced stability and ergonomic handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the container and handle are produced separately and then assembled, then the handle can be securely attached to the container body, but the manufacturing process becomes complex and labor-intensive
Solution Approach 1:
The patent merges the container body and handle into a single integrated component manufactured in one piece. The handle is formed as an integral part of the container body through injection molding, eliminating the need for separate production and assembly operations while maintaining secure attachment through the monolithic structure
2Ease of manufacture
If the handle is molded onto the container body in one piece, then the manufacturing process is simplified, but the handle must be securely attached without separate assembly steps
Solution Approach 1:
The container body and handle are merged into a single molded part, simplifying manufacturing to one operation while ensuring secure attachment through the integral structure where the handle is formed as part of the container body itself
Solution Approach 2:
The handle incorporates a hinge mechanism with material thinning that allows the handle to fold between storage and carrying positions. This dynamic design maintains secure attachment through the hinged connection while enabling the handle to assume different functional configurations
3Ease of operation
If the handle is hinged via material thinning designed as a film hinge, then the handle can be easily folded into carrying position, but the attachment point must be structurally sound
Solution Approach 1:
The material thinning is applied locally only at the hinge region where folding is required, while the surrounding attachment areas maintain full material thickness and structural integrity. This localized modification enables easy folding at the hinge point without compromising the strength of the overall attachment
