Lattice Egg Box with Resistance Barriers for Impact Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cardboard egg boxes are prone to humidity, leading to a short shelf life and egg damage during transport due to lack of resistance and ventilation, and require additional processes like stretch wrapping, limiting brand differentiation and increasing production costs.
Innovation Solution
A steel-constructed egg box with lattice structures and semi-elliptical cells for ventilation, resistance barriers, and a nesting lock system, eliminating the need for stretch wrapping and allowing easy opening and closing, while providing a carrying handle and stacking apparatus for secure transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If cardboard boxes are used for egg packaging, then production cost is low and ease of manufacture is high, but shelf life is short and resistance to humidity and impacts is poor
Solution Approach 1:
The egg box combines plastic base material with integrated lattice ventilation structures and resistance barriers, creating a composite packaging system that maintains the simplicity of single-material manufacturing while achieving superior mechanical strength, humidity resistance, and ventilation functionality simultaneously
Solution Approach 2:
The patent incorporates lattice structures with ventilation openings directly into the plastic body, creating a porous design that enables air circulation to extend shelf life while maintaining structural integrity and resistance to external pressures during transport
2Ease of manufacture
If cardboard boxes are used for egg packaging, then production cost is low, but shelf life is short due to lack of ventilation
Solution Approach 1:
The plastic egg box incorporates lattice structures with ventilation openings that allow continuous air circulation around the eggs, preventing moisture buildup and extending shelf life while maintaining a simple one-step injection molding manufacturing process that keeps production costs low
Solution Approach 2:
The ventilation lattice structures serve multiple functions simultaneously: they provide air circulation for extended shelf life, reduce condensation, maintain structural strength, and enable visual inspection of eggs, all within a single manufacturing process
3Strength
If stretch wrapping is used to secure eggs, then resistance to impacts is improved, but shelf life decreases due to prevented air circulation
Solution Approach 1:
The patent integrates resistance barriers and reinforced structural elements directly into the egg box design before the eggs are placed, providing built-in protection against impacts and stacking pressures while maintaining open lattice ventilation for continuous air circulation, eliminating the need for additional stretch wrapping
Solution Approach 2:
The design merges the protective function previously requiring separate stretch wrapping into the integral structure of the egg box itself, combining impact resistance, ventilation, and egg securing features into a single unified component that achieves both protection and air circulation
4Ease of manufacture
If cardboard boxes are used, then production cost is low, but brand differentiation is limited due to lack of visual appeal
Solution Approach 1:
The plastic egg box can be manufactured in various colors and visual forms through standard plastic coloring processes, allowing brands to differentiate their products while maintaining cost-effective single-step injection molding production without additional finishing processes
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

AI summary
The present invention relates to an egg box (1) which enables the eggs placed therein to be stored for a long time, to be carried and preserved. The inventive box (1) comprises cages (2) (3) which are resistant to impacts, have lattice structure with windows allowing air ventilation and prevent the eggs from being hit from the lower part. By means of the resistance barriers (6) provided in the lattice structure with windows, it prevents the eggs from being damaged by enabling the extra load on the lower boxes (1) to be absorbed when the egg boxes (1) are stacked on top of each other.
