Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing juice extractors require manual emptying of the pulp container for proper function, adding additional steps and inefficiency in operation.
Innovation Solution
A juice extractor design featuring a frustroconical rotating sieve with a transparent pulp container that allows visual inspection of the pulp filling state from all viewing directions, enabling efficient monitoring and timely emptying without interrupting operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the pulp container is integrated into the juice extractor, then the device structure is compact and space-saving, but the pulp container requires manual emptying which adds operational steps and reduces efficiency
Solution Approach 1:
The transparent outer wall enables the pulp container to provide self-monitoring functionality, allowing users to visually inspect pulp filling levels without manual intervention or disassembly, thus maintaining compact structure while improving operational efficiency
2Shape
If the pulp container is made opaque for structural integrity and aesthetics, then the device appearance is clean and simple, but the user cannot visually inspect the pulp filling state without disassembling the device
Solution Approach 1:
The outer wall is made transparent specifically in the regions where visual inspection is needed, while maintaining the overall structural integrity and aesthetic design of the device, allowing selective transparency to fulfill both appearance and monitoring requirements
3Ease of operation
If the outer wall is made completely transparent for full visual inspection, then the pulp filling state is easily monitorable, but the structural integrity and aesthetic appearance may be compromised
Solution Approach 1:
The outer wall uses transparent material specifically where visual inspection is required, while maintaining sufficient structural integrity through appropriate material selection and design, balancing transparency needs with structural requirements
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
Enables continuous monitoring of pulp levels, optimizing juice production by allowing users to prepare multiple portions before manually emptying the pulp container, reducing operational interruptions and enhancing user convenience.
Implementation Method 1
By exerting centrifugal forces to the juice and pulp due to the rotation of the shredding or grating disc, the juice and pulp are provided to a sieve surrounding the disc
Implementation Method 2
The outer wall is circumferentially transparent at least such that a pulp container filling state is visually inspectable for an operator from outside in all viewing directions

AI summary
The present invention relates to a juice extractor. In order to provide an improved pulp handling, a juice extractor (10) comprises a grating disc (22) to grate food into juice and pulp, a feeding tube (20) to feed food to the grating disc, a rotating sieve (26) to separate juice and pulp, a juice collector (40), a pulp container (42) enclosing a pulp collection volume (44), an upper housing cover (50), and a base housing (52). The sieve is of a frustroconical form extending in diameter along the feeding direction from a top end (30) to a bottom end (32), such that the top end has a smaller diameter than the bottom end. During use, the juice is transported to the outside of the sieve, and the pulp is discharged to the pulp container arranged below the sieve. The juice collector is provided with a circumferential receptacle (48) connected to a discharge port (46), wherein the circumferential receptacle is provided such that juice transported to the outside of the sieve is collected. The upper housing cover is supported by the juice collector. Further, the pulp container comprises an outer wall (54), which outer wall is provided as a single-shell housing portion (56) resting on the base housing and supporting the juice collector. The outer wall encloses the pulp collection volume in a radial direction.
