Packaging Handle Compensation Mechanism for Gapless Lifting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Packaging for heavy or large products often struggles with maintaining structural integrity and aesthetic appeal, particularly when lifting, as existing designs may create gaps between components, leading to instability and user discomfort, while also facing challenges in being eco-friendly and cost-effective.
Innovation Solution
A split box design with a handle compensation mechanism, where the upper lid and lower base box are connected via a detachable strap, allowing the handle to move vertically and absorb slack, maintaining a gapless interface during lifting, and using cellulose-based materials for eco-friendliness and recyclability, along with additional support walls and cushioning elements for enhanced stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a traditional rigid connection between upper lid and lower base box is used, then structural stability is maintained, but the packaging creates gaps and loses aesthetic appeal during lifting
Solution Approach 1:
The patent applies the dynamics principle by transitioning from a rigid fixed connection to a dynamic flexible connection using a strap. The strap can flex and extend during lifting operations, allowing the upper lid and lower base box to move independently while maintaining connection. This dynamic connection prevents gap formation and maintains aesthetic appearance while preserving structural stability during the lifting process.
2Shape
If a flexible connection is used between upper lid and lower base box, then aesthetic appeal is maintained during lifting, but lifting force is insufficient for heavy products
Solution Approach 1:
The patent applies the composite materials principle by creating a hybrid connection system that combines properties of both rigid and flexible elements. The strap serves as a flexible component that maintains aesthetic appeal, while the detachable rigid connection mechanism (such as clips or fasteners) provides the necessary lifting force for heavy products. This composite approach integrates the advantages of both connection types to resolve the contradiction between aesthetics and lifting capability.
3Object-affected harmful factors
If packaging is designed to be environmentally friendly using recyclable materials, then eco-friendliness is improved, but structural strength may be reduced
Solution Approach 1:
The patent applies the parameter changes principle by optimizing the physical and mechanical parameters of recyclable materials to achieve the required structural strength. This includes selecting recyclable materials with appropriate thickness, density, and structural design (such as corrugated patterns or reinforced walls) that maintain sufficient strength while remaining environmentally friendly. The parameter optimization allows the packaging to meet both eco-friendliness and structural strength requirements.

AI summary
Packaging is provided including an upper lid having a handle disposed within a channel of a surface of the upper lid and vertically movable within the channel. A lower base box is coupled to the handle via a strap, such that a lifting force imparted to the handle lifts the lower base box when the strap becomes taut. The vertical movement of the handle within the channel overcomes any slack in the strap such that the handle does not contact an upper vertical surface in the upper lid, but a gapless interface between the upper lid and lower base box is maintained during lifting of the packaging. The strap is detachable from the handle and from the base box, such that it may be removed in order to open packaging by lifting the lid off of the base box.
