Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable cases lack effective inserts that can securely store and transport articles of varying shapes and sizes without damage, and existing solutions often require pre-cut inserts that may not fit perfectly or provide adequate protection.
Innovation Solution
A portable case with a cavity that uses liquid dispersed memory foam inserts, which are formed to conform to the surface profile of the article, providing a secure and customizable fit, and can include elastomeric layers for added protection and graphic features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If pre-formed and trimmed inserts are used to approximate article surface contours, then the insert can be manufactured with standard dimensions, but the fit may not be perfect and protection may be inadequate
Solution Approach 1:
The patent applies parameter changes by transitioning from solid foam to liquid dispersed memory foam, which changes the physical state and properties of the material. This allows the insert to flow and conform to the cavity shape during manufacturing, then rebound to provide precise fit and protection, resolving the contradiction between ease of manufacture and fit precision.
Solution Approach 2:
The patent uses composite materials by combining liquid dispersed memory foam with elastomeric layers. The memory foam provides shock absorption and conformability, while the elastomeric layers add durability and can be patterned for graphics. This composite approach achieves both ease of manufacture and high precision fit.
2Manufacturing precision
If liquid dispersed memory foam is used to conform to cavity surface profile, then a secure and customizable fit is achieved, but the manufacturing process becomes more complex
Solution Approach 1:
The liquid dispersed memory foam is self-servicing in that it automatically conforms to the cavity shape without requiring complex tooling or manual trimming. The material flows into the cavity, takes the desired shape, and then rebounds to provide the secure fit, simplifying the manufacturing process while achieving high precision.
Solution Approach 2:
By changing the material from solid to liquid dispersed state, the patent enables the foam to flow and conform to the cavity during manufacturing, then rebound to provide the secure fit. This parameter change simplifies the manufacturing process while achieving high precision conformability.
3Strength
If elastomeric layers are added to the insert, then durability and graphic features are enhanced, but the insert structure becomes more complex
Solution Approach 1:
The patent combines liquid dispersed memory foam with elastomeric layers to create a composite insert structure. The memory foam provides shock absorption and conformability, while the elastomeric layers add durability and can be patterned for graphics. This composite approach enhances strength without requiring complex structural elements.
Solution Approach 2:
The elastomeric layers are applied locally to specific areas of the insert where durability and graphic features are needed. This localized application enhances strength and aesthetic appeal without requiring the entire insert structure to be complex, maintaining simplicity where possible.
