Lightweight Container Handle Attachment via Neck Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Lightweight containers are not strong enough to withstand the force required for applying conventional handles, limiting their weight reduction potential.
Innovation Solution
A method and apparatus for attaching a handle to a container using the container's neck as support, involving a neck guide rail, handle applicator, and application chuck to secure the handle without collapsing the container, optionally with compressed gas for increased rigidity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If conventional handles are applied to containers by pressing them over the mouth, then the handle attachment is simple, but lightweight containers collapse under the application force
Solution Approach 1:
The patent introduces an intermediary support system consisting of support plates and guide rails that temporarily support the container during handle application. This mediator absorbs the application force, preventing the lightweight container from collapsing while the handle is being attached to the neck.
Solution Approach 2:
The patent performs preliminary support preparation by positioning support plates and guide rails before the handle application force is applied. The container is pre-supported in a controlled manner, allowing the subsequent handle application to proceed without causing structural failure.
2Loss of substance
If container weight is reduced to meet environmental demands, then material usage decreases, but the container cannot withstand the force required for handle application
Solution Approach 1:
The support plates and guide rails act as intermediaries that bridge the gap between the handle application force and the lightweight container structure. They provide the necessary mechanical support during the critical attachment phase, enabling the use of reduced material quantities without compromising the handle application process.
Solution Approach 2:
The patent changes the mechanical parameters of the container system by introducing external support structures that alter the force distribution. The support plates distribute the application force across multiple contact points, effectively increasing the container's load-bearing capacity during handle attachment without adding permanent structural weight.
3Strength
If support structures are added to prevent container collapse, then container strength during application increases, but device complexity increases
Solution Approach 1:
The support system is segmented into distinct functional components: support plates for vertical support, guide rails for lateral positioning, and application chucks for handle attachment. This segmentation allows each component to perform its specific function efficiently and enables easy adjustment or removal of individual elements based on container requirements.
Solution Approach 2:
The guide rails and support plates are designed to serve multiple functions: they provide structural support, guide the handle application process, and can accommodate different container sizes and shapes. This multi-functionality reduces the need for specialized components for each container type, thereby managing device complexity while maintaining versatility.

AI summary
A method for applying a handle to a container, including placing the handle on the neck of the container, supporting the container to prevent the container from collapsing, and moving the handle toward an end of the neck that contacts a body of the container. The neck includes a supporting rib to fix the handle to the container.
