Moulded Pulp Packaging with Counter-Embossed Label
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional packaging units for products like eggs are prone to damage from loads and forces during storage and transport, leading to loss of display properties and increased packaging costs, and the labels can become unreadable and less attractive.
Innovation Solution
A packaging unit with a moulded pulp bottom and cover part featuring a multi-sided embossed label with counter-embossing, which enhances strength, stability, and visual appeal, while reducing material usage and production costs, and includes a locking mechanism for secure closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional packaging units are provided with sufficient strength to prevent damage during storage and transport, then product protection is improved, but packaging material usage increases and costs rise
Solution Approach 1:
The patent applies local quality by adding embossments specifically at critical stress points and structural locations on the packaging unit, rather than uniformly thickening the entire structure. This localized reinforcement provides enhanced strength where needed while maintaining material efficiency elsewhere, directly resolving the contradiction between product protection and material usage.
Solution Approach 2:
The patent employs composite construction by combining moulded pulp material with strategically placed embossed reinforcement elements. This composite approach creates a packaging structure that achieves superior strength-to-weight ratio, protecting products during transport while minimizing overall material consumption compared to conventional uniform-thickness designs.
2Reliability
If conventional packaging units are provided with sufficient strength to prevent damage during storage and transport, then product protection is improved, but packaging costs increase
Solution Approach 1:
The patent merges the structural reinforcement function with the informational label function by integrating embossed elements that serve both purposes. The embossments provide structural strength while simultaneously creating raised relief areas for labels, reducing the need for separate reinforcement components and lowering overall manufacturing costs.
Solution Approach 2:
The patent utilizes parameter changes by varying the depth, shape, and distribution of embossments to optimize both protective performance and manufacturing efficiency. By adjusting these geometric parameters, the design achieves adequate product protection while maintaining cost-effectiveness through simplified production processes.
3Reliability
If loads and forces act on conventional packaging units during storage and transport, then product protection is maintained, but visual appearance and label readability deteriorate
Solution Approach 1:
The patent applies beforehand cushioning by incorporating pre-formed embossed structures that act as stress-absorbing elements. These embossments are designed to deform preferentially under load, absorbing impact forces before they can damage the packaging unit or distort the label, thereby maintaining visual appearance and readability while protecting the product.
Solution Approach 2:
The patent implements preliminary anti-action by creating embossed reinforcement features that counteract the deforming effects of transport loads. These pre-positioned structural elements resist shape changes and label distortion before they occur, preserving the packaging's visual appearance and information display under various loading conditions.
