Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing food presses are inefficient, difficult to operate, and hard to clean, with issues such as misalignment, material escape, wear, and ergonomic challenges, particularly in double-hinged designs.
Innovation Solution
A double-hinged food press system with a plunger unit, receiver unit, and grate, featuring rotatable components, rollers, and a plunger seal lip for a tight fit, allowing for easy operation and cleaning, and the ability to be used on support surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a double-hinged food press design is used, then the press can be operated on support surfaces with ergonomic support, but the device becomes more complex and difficult to operate due to misalignment and material escape issues
Solution Approach 1:
The press is divided into two separate hinged units: a plunger unit and a receiver unit, connected by a hinge. This segmentation allows each unit to be optimized independently while maintaining the overall double-hinged structure, reducing complexity through modular design
Solution Approach 2:
The double-hinged design introduces dynamic movement between the plunger unit and receiver unit, allowing the press to adapt to different support surfaces and operating positions, improving ergonomics while maintaining functional simplicity through controlled motion
2Ease of manufacture
If traditional food press designs are used, then the structure is simple, but the press is difficult to clean due to material escape and misalignment
Solution Approach 1:
The grate is made detachable from the receiver unit, allowing it to be easily removed for cleaning. This extraction of the grate component eliminates the difficulty of cleaning trapped material, while the simple hinge connection maintains structural simplicity
Solution Approach 2:
The design incorporates features that prevent material escape during operation, such as proper alignment guides and containment structures, so that cleaning is simplified afterward by preventing material buildup in the first place
3Reliability
If a tight-fitting plunger design is used, then material escape is reduced, but wear increases due to friction and contact
Solution Approach 1:
A flexible plunger seal lip is incorporated to create a tight seal between the plunger and receiver cup walls, preventing material escape. The flexibility of the seal lip allows it to conform to the cavity shape while reducing friction and wear compared to rigid tight-fitting designs
Solution Approach 2:
The plunger assembly uses composite construction with the plunger body made of durable material and the seal lip made of flexible, wear-resistant material, combining the advantages of structural integrity and low-friction sealing

AI summary
A double-hinged food press for extruding foodstuff through a grate and operational by hand while held aloft or placed on a work surface. An upward-curved plunger handle, combined with a receiver handle designed to rest on the surface, positions the press for the operation. Rollers enable the grate to be snapped smoothly over risers into and out of recesses in the receiver without undue wear and resulting loss of integrity. A raised lip of resilient material surrounding a plunger face further ensures a tight fit between the plunger and receiver cup. Resilient material between the plunger face and the hinge barrel of the grate ensures a tight fit between the two. Hinge pins may be removed by the user for replacement of the grate. Bosses can extend from the receiver unit for support on the surface to assist in operation of the press. An attachable paddle can be used to collect extruded material and to scrape it from the grate.
