Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging for fragile goods is costly, cumbersome, environmentally unsustainable, prone to fatigue and breakage, and insufficiently thermally insulating, making it difficult to manufacture and dispose of.
Innovation Solution
A flat-pack packaging design featuring a base and rotatable cover made from sustainable materials like recycled cardboard, with inner and outer walls and tabs for secure item holding, allowing assembly by machine and providing thermal insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional packaging (vacuum moulded, injection moulded, thermo-plastically moulded) is used to conform to the object shape, then protection is improved, but manufacturing cost and complexity increase
Solution Approach 1:
The packaging is divided into separate components: a base with sidewalls defining an internal volume, and a rotatable cover that closes the opening. This segmentation allows for simpler manufacturing of individual parts while maintaining protective functionality when assembled.
Solution Approach 2:
The invention transitions from complex moulded packaging to flat-pack cardboard construction, changing the physical state and assembly parameters. The flat-pack design can be easily manufactured and stored, then assembled into a protective structure when needed.
2Reliability
If conventional protective packaging is used, then protection is improved, but weight and bulk increase
Solution Approach 1:
The packaging uses thin cardboard walls and flaps to create a protective structure, replacing heavy rigid materials. The rotatable cover and inner base wall create protective chambers using minimal material thickness while maintaining strength.
Solution Approach 2:
The design creates three-dimensional protective volume from two-dimensional flat-pack materials through folding and rotating operations. The rotatable cover transitions from a flat state to a closed position, creating protective enclosure without adding significant weight.
3Reliability
If conventional protective packaging is used, then protection is improved, but environmental sustainability deteriorates
Solution Approach 1:
The invention changes the material parameter from conventional plastics and foams to cardboard and paper-based materials. This parameter change enables the packaging to be recyclable and biodegradable while maintaining protective functionality through clever structural design.
Solution Approach 2:
The packaging design facilitates recovery and recycling of cardboard materials. The rotatable cover and modular construction allow for easy disassembly and material recovery, reducing environmental impact compared to traditional single-use plastic packaging.
4Ease of manufacture
If flat-pack packaging is used to reduce weight and cost, then manufacturing cost decreases, but structural strength and thermal insulation deteriorate
Solution Approach 1:
The design employs nested structures with an inner base wall spaced apart from the outer base wall, and an inner cover wall spaced apart from the outer cover wall. These nested chambers create protective zones that enhance structural strength while using minimal material.
Solution Approach 2:
The spaced inner walls create air gaps that act as cushioning elements before impact reaches the packaged item. This beforehand cushioning protects the contents while using simple flat-pack construction.
5Ease of manufacture
If flat-pack packaging is used to reduce weight and cost, then manufacturing cost decreases, but thermal insulation deteriorates
Solution Approach 1:
The nested inner base wall and inner cover wall create multiple air-filled chambers that provide thermal insulation. These air gaps act as thermal barriers, keeping perishable goods at stable temperatures while using inexpensive cardboard construction.
Solution Approach 2:
The thin cardboard walls and air gaps create a thermal barrier similar to flexible insulation layers. This passive thermal insulation protects perishable items during transport without requiring active cooling systems.

AI summary
Protective packaging is described that includes a base having an outer and an inner base wall. A plurality of sidewalls extends from the outer base wall to define an internal volume and an opening. The internal volume is opposite the outer base wall. The inner base wall is disposed within the internal volume spaced apart from the outer base wall. A cover includes an outer cover wall and an inner cover wall. The cover is rotatably attached to at least one sidewall. The cover is rotatable between a closed position in which the cover closes the opening and an open position in which the cover does not close the opening. In the closed position, the inner cover wall is within the internal volume and spaced apart from the outer cover wall and the inner base wall. The inner base wall and the inner cover wall receive or house an item.
