Foldable pour over coffee dripper
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pour over coffee drippers are bulky and difficult to store or travel with due to their fixed shape and volume.
Innovation Solution
A foldable pour over coffee dripper design featuring a standing wall, a supporting frame, a basal plate, and a helical coil filter unit that can be compressed and folded for reduced volume, allowing easy storage and travel, with the filter unit's conical shape and single continuous strand construction enabling efficient compression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If conventional pour over coffee drippers are made of plastic, stainless steel, ceramic, or glass, then they maintain structural integrity and brewing functionality, but they occupy a certain volume and cannot be folded or stored easily
Solution Approach 1:
The dripper is divided into multiple segments: a standing wall, a supporting frame with first and second annular frames, a basal plate, and a filter unit. These segments can be folded relative to each other through pivot connections at the ear portions and concave grooves, enabling compact storage while maintaining structural integrity during use.
Solution Approach 2:
The supporting frame and basal plate are designed to be movable relative to the standing wall through pivot connections. The first base portion pivots at the first ear portions, and the second base portion pivots at the second ear portions, allowing the structure to transition between an extended brewing configuration and a folded storage configuration.
2Ease of operation
If conventional coffee drippers use a fixed shape design, then they maintain brewing performance, but they are difficult and inconvenient to travel with or carry outdoors
Solution Approach 1:
The dripper employs dynamic folding mechanisms where the supporting frame can pivot at the first ear portions and the basal plate can pivot at the second ear portions. This allows the structure to collapse into a compact form factor for travel while maintaining its functional shape during brewing operations.
Solution Approach 2:
When folded, the supporting frame and basal plate rest parallel to the standing wall, with the filter unit compressed within the circular hole of the supporting frame. This nested arrangement minimizes the overall volume for storage and transport.
3Volume of moving object
If the filter unit is made with a conical shape and single continuous strand construction, then it enables efficient compression for storage, but it requires precise manufacturing
Solution Approach 1:
The filter unit is formed with a conical shape created by a single continuous strand arranged in a helical coil pattern. This curved, tapered geometry naturally compresses along its axis, allowing the filter to be compacted into a small volume for storage while maintaining its filtering function when deployed.
