Cooking Hob Chassis Assembly Using Segmented Bracket Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooking devices require large and material-intensive connecting elements to fix the cooking hob to the chassis, leading to inefficiencies in design and material consumption.
Innovation Solution
The cooking device employs a simplified structure with L-shaped brackets that include lower, upper, and horizontal taps, as well as vertical front taps, to securely attach the hob frame, control panel, and protection box, using fewer and more compact connecting elements, allowing for efficient fixation and reduced material usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional connecting elements are used to fix the cooking hob to the chassis, then the connection is stable and secure, but the connecting elements are large in size and consume much material
Solution Approach 1:
The connecting element is divided into multiple functional parts: a bracket with L-shaped profile section that attaches to the side wall, front fixing elements for the hob frame, and rear fixing elements. This segmentation allows each part to be optimized for its specific function while using minimal material, replacing traditional large monolithic connecting elements.
Solution Approach 2:
The bracket serves multiple functions: it provides structural support for the cooking hob, acts as a mounting platform for front and rear fixing elements, and enables both mechanical attachment and positioning. This multi-functionality eliminates the need for separate supporting structures, reducing overall material consumption while maintaining connection stability.
2Loss of substance
If fewer connecting elements are used to reduce material consumption, then material usage is optimized, but the connection stability and security may be compromised
Solution Approach 1:
The bracket is designed with an L-shaped profile section that provides localized structural strength at critical attachment points. The vertical and horizontal sections are positioned to distribute loads efficiently, ensuring connection stability is maintained at the most stressed locations while using minimal material overall.
Solution Approach 2:
The bracket is pre-attached to the side wall of the chassis before the hob is installed. This preliminary action creates a stable foundation that distributes connection forces across multiple attachment points, ensuring that when the hob is secured, the connection is stable and secure without requiring excessive material in the final assembly.

AI summary
The present invention relates to a cooking device with at least one chassis (10) and at least one cooking hob (36, 38, 40). The chassis (10) includes two side walls (12), a front wall or front frame (14) and rear wall (16) or rear frame. Each the side wall (12) comprises an upper border (18) formed as flange. A hinge bracket (20) is detachably fixed or fixable on a front portion of each upper border (18). A control panel (30) is detachably fixed or fixable at the hinge brackets (20). A protection box (36) forms a lower part of the cooking hob and is detachably arranged or arrangeable on the chassis (10). The protection box (36) is clamped or clampable between the hinge brackets (20) and the rear wall (16) or rear frame. At least two front fixing elements (32) are detachably fixed or fixable on the hinge brackets (20). At least two rear fixing elements (34) are detachably fixed or fixable on the rear portions of the upper border (18). A hob frame (40) is detachably arranged or arrangeable on the front fixing elements (32) and on the rear fixing elements (34).
