Ridge-Structured Blister Package for Drop Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional blister packages for personal care products lack sufficient protection against drops, load compression, and vibration, leading to potential damage and poor product visibility on point-of-sale displays, which affects consumer recognition and purchase decisions.
Innovation Solution
The package design incorporates a ridge and cavities for enhanced stability, a transparent rear blister for product information, and stacking and denesting lugs, using materials like polyethylene terephthalate (PETG) and recycled PETG, with a ridge that acts as a dampening element to absorb forces and improve structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional blister packages are used with clear plastic and card material, then product visibility is good, but protection against drops, load compression, and vibration is insufficient
Solution Approach 1:
The patent incorporates a ridge structure and cavities within the package body that act as cushioning elements before damage occurs. These features are designed to absorb and distribute impact forces from drops, compression loads, and vibration during shipping and handling, protecting the contents while maintaining package transparency for product visibility.
Solution Approach 2:
The package utilizes composite construction combining clear plastic blister material with reinforced structural elements. The ridge and cavity features create a composite structure that maintains the transparent aesthetic for visibility while adding structural integrity and protective characteristics against mechanical damage.
2Ease of manufacture
If the package structure is simplified for easy manufacturing, then manufacturing cost decreases, but structural support and protection capability are reduced
Solution Approach 1:
The package structure is segmented into distinct functional zones: a clear plastic blister section for visibility, a ridge section for structural reinforcement, and cavity sections for cushioning. This segmentation allows each component to be manufactured using standard processes while collectively providing enhanced protection and structural support.
Solution Approach 2:
The ridge and cavity features are strategically positioned in specific locations where mechanical stress is most likely to occur during handling and shipping. This local reinforcement approach provides maximum structural support and protection exactly where needed, rather than uniformly thickening the entire package, thus maintaining ease of manufacture while strengthening critical areas.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution significantly increases the force required to bend or flex the package, providing better protection against damage and enhancing consumer recognition of product features, resulting in improved sales and reduced packaging failures.

AI summary
A package includes a first member and a second member. The second member and the first member define a first cavity. A periphery of the first member is joined to a periphery of the second member to define a sealed portion, such that respective perimeters of the first member and the second member cooperate to define an outer edge of the sealed portion. The second member includes a ridge at least partially circumscribing the first cavity while remaining inward of the outer edge. The ridge includes an inner wall, an outer wall, and a rim. Both the inner wall and the outer wall extend rearward from and substantially perpendicularly relative to the first member and are connected by the rim. At least a portion of the rim, over a length of the ridge, is substantially parallel to the first member.
