Folding-Arm Food Preparation Appliance With Folded-Position Drive Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing household food preparation appliances are limited by offering only one working position and type of tool, which restricts their functionality and require adapters for optimal use, compromising ergonomics and efficiency.
Innovation Solution
A household food preparation appliance with a upper arm that folds over the lower arm, allowing multiple working positions, including vertical and horizontal configurations, and incorporating a speed reducer box to adapt the driver's speed for various accessories, along with a motor positioned for compactness and ease of use, enabling versatile operation with different tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the upper arm is fixed in a single position, then the device structure is simple, but the versatility and functionality are limited
Solution Approach 1:
The patent applies the dynamics principle by making the upper arm movable relative to the lower arm through a hinge connection. This allows the upper arm to transition between different positions (folded and unfolded states), enabling the device to accommodate multiple working positions and tool types without requiring a completely fixed rigid structure.
Solution Approach 2:
The patent divides the arm structure into two separate segments: a lower arm and an upper arm connected by a hinge. This segmentation allows each arm to be independently positioned and configured, providing versatility in working positions while maintaining structural simplicity through modular design.
2Volume of moving object
If the motor is positioned far from the driver, then the driver can be accessed easily, but the device size increases and compactness is reduced
Solution Approach 1:
The patent applies the nesting principle by placing the motor within a housing that forms a protrusion on the underside of the upper arm. The motor housing is inserted at least partially into a corresponding opening in the lower arm when the upper arm is in the folded position, allowing compact integration of the motor while maintaining accessibility to the driver through the opening.

AI summary
The invention relates to a household food preparation appliance comprising a base (1) intended to be placed flat on a work surface, a lower arm (2) borne by the base (1) and an upper arm (3) comprising a rear end connected to the lower arm (2) by a hinge means. The upper arm (3) comprises at least one drive mechanism (42) rotated by a motor (4) and intended to be coupled to a food processing accessory, said drive mechanism (42) opening at a lower face of the upper arm (3). The appliance is characterised in that the upper arm (3) can occupy a folded position, in which the upper arm (3) extends along the length of the lower arm (2) with the lower face of the upper arm (3) positioned facing the lower arm (2), and in that the lower arm (2) comprises a through-hole (21) providing access to the drive mechanism (42) when the upper arm (3) is in the folded position.
