Integrated Handle Closure Device for Food Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging devices for food products face challenges in easy manipulation and transportation due to the need for additional handles, which increase manufacturing costs, weight, and storage constraints.
Innovation Solution
A closure device with an integrated handle and securing means, made from the same material as the cap, facilitates gripping and handling while reducing manufacturing costs and weight by using a film that can be cut and stretched for multiple applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an additional handle is added to the pot for easy handling and transportation, then the ease of operation is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent integrates the handle directly into the closure cap structure, merging two previously separate components (handle and cap) into a single unified structure. This eliminates the need for additional attachment steps and reduces overall device complexity while maintaining ease of handling.
Solution Approach 2:
The closure cap serves multiple functions: it seals the pot and simultaneously provides a handle for carrying. This multi-functionality reduces the number of separate components needed, simplifying the overall device structure while improving ease of operation.
2Ease of operation
If an additional handle is added to the pot for easy handling, then the ease of operation is improved, but the manufacturing cost increases
Solution Approach 1:
By combining the handle and cap into a single integrated component, the patent eliminates separate manufacturing and assembly steps for attaching a handle. This reduces manufacturing complexity and cost while maintaining the ease of handling benefit.
Solution Approach 2:
The integrated handle-cap structure is self-contained and requires no additional attachment processes. The handle is inherently part of the cap structure, eliminating the need for separate fastening operations and reducing manufacturing costs.
3Ease of manufacture
If the pot is made with an integrated handle during a single injection operation, then the ease of manufacture is improved, but the material consumption and weight increase
Solution Approach 1:
The patent separates the handle-cap assembly from the pot body, allowing each component to be optimized independently. The cap with integrated handle can be made from lightweight materials or thin-walled construction, reducing overall weight while maintaining ease of manufacturing.
Solution Approach 2:
The cap structure, including the integrated handle, can be designed with thin-walled construction or flexible material usage, reducing material consumption and weight while maintaining structural integrity and ease of manufacturing.
4Ease of operation
If a handle is added to the pot, then the ease of operation is improved, but the storage and transport capacity is reduced due to increased lateral extension
Solution Approach 1:
The handle is nested within or integrated into the cap structure rather than extending outward from the pot body. This allows the handle to occupy space that would otherwise be part of the cap volume, minimizing the increase in lateral extension and preserving storage capacity.
Solution Approach 2:
Instead of extending the handle laterally outward from the pot, the patent positions the handle in a different spatial arrangement - integrated into the cap's vertical or radial structure. This dimensional repositioning reduces the lateral footprint and preserves storage capacity while maintaining handling ease.
