Heatable Food Processor Lid Venting for Cool, Dry Handle Grip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing food processors face issues with uncontrolled steam escape during cooking, leading to high temperatures and impaired handling due to steam condensation on handles and potential dripping of condensate onto surfaces.
Innovation Solution
A design where a support edge on the lid of the food processor creates a predetermined steam path between the handle and the lid edge, guiding steam away from the handle and preventing condensation, with the handle connected only over a partial area and positioned laterally to the connection point, allowing steam to escape in a controlled manner without additional seals or special materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If the lid is placed directly on the cooking vessel with steam escape openings, then steam can escape during cooking, but the steam escapes in an uncontrolled manner causing high temperatures and impaired handling
Solution Approach 1:
The patent applies local quality by creating a specific localized path for steam escape between the handle and lid edge, rather than uniform steam distribution. The support edge structure concentrates steam flow into a defined channel, giving different regions of the lid different functions: the handle area remains steam-free for safe handling, while the steam path area allows controlled escape.
Solution Approach 2:
The support edge acts as an intermediary element that mediates between the steam generation area and the handle area. It creates a controlled interface that allows steam to pass through a predetermined path while blocking steam from reaching the handle, thus protecting the handle from heat and condensation.
2Ease of operation
If additional means such as seals or special surface structures are used to prevent condensation on the handle, then the handle remains dry, but the device complexity increases
Solution Approach 1:
The patent implements self-service by allowing the lid structure itself to prevent condensation on the handle through its geometric design. The support edge and handle arrangement automatically create a steam escape path that prevents condensation without requiring additional active components, seals, or special surface treatments.
Solution Approach 2:
The lid is segmented into different functional zones by the support edge structure. The handle connection area is separated from the main lid body, creating a distinct region where steam can escape laterally. This segmentation allows the handle to remain in a dry, cool zone while the steam escapes through the designated path.
3Strength
If the handle is connected to the lid edge over the full width, then the handle is securely attached, but steam condenses on the handle and causes dripping
Solution Approach 1:
The handle connection is applied locally rather than across the full width of the handle. The support edge creates a localized attachment point that provides sufficient mechanical strength while leaving the majority of the handle width open for steam escape. This local connection strategy maintains structural integrity while preventing condensation.
4Adaptability or versatility
If the lid is designed with overhanging handles for secure placement, then the lid can serve as a coaster, but steam escape paths are blocked
Solution Approach 1:
The patent resolves the conflict by utilizing a different spatial dimension for steam escape. Instead of trying to escape steam horizontally from under the overhanging handle, the design allows steam to escape laterally at the connection area between the handle and lid edge. This vertical-to-lateral dimension change enables both the coaster function and steam escape.
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
This solution ensures the handle remains cool and dry, preventing condensation and dripping, while allowing the lid to function as a coaster for the vessel in upside-down positions, maintaining a safe touch temperature and improving handling safety.
Implementation Method 1
steam can escape, for example during the course of a cooking process
Implementation Method 2
prevents the steam from condensing on the handle

AI summary
The invention relates to a food processor (1) having a heatable vessel in the lower region thereof, particularly a mixing vessel (3), wherein the vessel (3) is covered by a cover (17), and the cover (17) can be handled by means of at least one handle (22) laterally protruding over the vessel (3), wherein steam produced in the vessel (3) can escape between the cover (17) and a vessel wall. In order to further improve a food processor of the type mentioned above particularly in terms of handling, the invention provides that a path (25) is predetermined for the steam in the region of the handle (22) between the handle (22) and a cover edge (20).
