Nested Cook-Set Design for Compact Brewing and Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable cook sets for brewing coffee require multiple separate items, including a cook pot, press pot, and insulated storage container, which occupy significant space, making them impractical for backpacking and camping where storage space is limited.
Innovation Solution
A nested cook-set design that integrates a cook pot, a press-pot piston, and a vacuum bottle in a compact, coaxial arrangement, allowing for brewing, filtering, and storage in a single unit, with the press-pot piston capable of receiving the vacuum bottle and cook pot, enabling efficient use and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional separate items (cook pot, press-pot, insulated storage container) are used for brewing coffee, then brewing functionality is achieved, but storage space is significantly occupied
Solution Approach 1:
The patent implements nesting by placing the vacuum bottle inside the press-pot, and the press-pot inside the cook pot. This nested arrangement allows all three separate items to occupy the same spatial envelope, dramatically reducing the storage volume required while maintaining all brewing and storage functionalities.
Solution Approach 2:
The patent combines multiple separate brewing and storage items into a single integrated nested system. The cook pot, press-pot, and vacuum bottle are merged into one compact unit that can be stored together, eliminating the need to carry multiple separate items while preserving all their individual functions.
2Adaptability or versatility
If multiple separate items are carried for cooking and storage, then functionality is complete, but device complexity increases
Solution Approach 1:
The nested system provides multi-functionality where the same set of components serves multiple purposes: the cook pot for heating, the press-pot for brewing and filtering, and the vacuum bottle for insulated storage. This universal design reduces the number of specialized items needed while maintaining complete cooking and storage functionality.
3Ease of operation
If conventional cook pot with plunger-style press is used, then coffee brewing is achieved, but space efficiency is reduced
Solution Approach 1:
The press-pot with its plunger-style press mechanism is nested inside the cook pot, and the vacuum bottle is nested inside the press-pot. This nesting arrangement allows the brewing device to maintain its full functionality while occupying minimal storage space when not in use.
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 nested cook-set allows for efficient brewing and storage of coffee while minimizing space requirements, as it can be disassembled and reassembled for convenient transportation and storage, providing a compact solution for outdoor activities.
Implementation Method 1
A vacuum bottle is an insulating storage vessel that greatly lengthens the time over which its contents remain hotter or cooler than the vacuum bottle's surroundings. The gap between the outer body and inner liner is partially evacuated of air, creating a near-vacuum which significantly reduces heat transfer by conduction or convection.

AI summary
A portable nested cook-set includes a cook pot having a pot sidewall with a retention projection and defining an upwardly opening pot interior chamber, a press-pot piston having a piston sidewall and a lower end portion defining an upwardly opening piston interior chamber, and a storage container having an exterior portion and a selectively sealable interior storage chamber. The piston sidewall has a sidewall opening and a retention notch positioned to removably receive the retention projection therein. The press-pot piston sidewall is dimensioned to be selectively storable at least partially within the cook pot. The storage container having an exterior portion with a lower portion dimensioned to be selectively storable at least partially within the piston interior chamber. The storage container and the press-pot piston being releasably threaded together.
