Solution Overview
Problem
Cosmetic items in portable storage units often suffer damage due to elevated temperatures, as there is no known solution to maintain stable temperatures within these units, leading to melting and rendering the products useless.
Innovation Solution
A portable storage unit with a thermal liner made of heat-resistant fabrics, including non-woven materials and phase change materials, to maintain stable temperatures and prevent damage from heat and moisture exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a portable storage unit is made from conventional materials, then it is lightweight and inexpensive, but the interior temperature becomes elevated causing cosmetic damage
Solution Approach 1:
The patent applies composite materials by combining multiple fabric layers with different functional properties: an outer shell fabric for structural integrity, a thermal liner fabric with insulating properties, and an inner lining fabric for cosmetic contact. This multi-layer composite structure provides thermal protection while maintaining portability and aesthetic appearance.
Solution Approach 2:
The patent applies local quality by providing thermal protection specifically where needed - the thermal liner is positioned directly around the cosmetic storage compartment to provide localized insulation. The outer shell and inner lining maintain different properties optimized for their specific functions (structural integrity and cosmetic contact respectively).
2Reliability
If no thermal protection is added, then the storage unit remains simple and affordable, but cosmetics melt and are damaged
Solution Approach 1:
The patent uses composite materials consisting of multiple fabric layers including a thermal liner with insulating properties sandwiched between an outer shell and inner lining. This composite fabric construction provides reliable thermal protection for cosmetics while remaining compatible with standard textile manufacturing processes.
Solution Approach 2:
The patent applies parameter changes by selecting fabrics with specific thermal properties - the thermal liner fabric has higher thermal resistance compared to conventional single-layer fabrics. This parameter change in material selection provides protective functionality without fundamentally altering the manufacturing approach.
3Object-affected harmful factors
If heat-resistant materials are used, then temperature stability is improved, but the storage unit becomes more complex
Solution Approach 1:
The patent applies local quality by concentrating thermal protection functionality in a specific layer - the thermal liner - while other layers (outer shell and inner lining) maintain their respective functions for structure and cosmetic contact. This localized approach provides heat resistance without requiring all components to be complex heat-resistant materials.
Solution Approach 2:
The patent uses composite materials to combine the heat-resistant thermal liner with conventional outer shell and inner lining fabrics. This composite construction provides necessary thermal protection while using simpler, more conventional materials for the structural and cosmetic-contact portions.
