Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hob devices face challenges in accurately centering user interface elements relative to the user interface area, leading to assembly tolerances and manufacturing tolerances affecting the positioning.
Innovation Solution
A hob device with a centering unit that includes a centering element attached to the hob, which is connected via an adhesive element, ensuring precise centering of the user interface element along desired directions, thereby reducing assembly and manufacturing tolerances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional receptacles and centering pins are used to center the user interface element, then the assembly structure is simple, but the positional tolerance of the user interface element relative to the user interface area is large due to manufacturing tolerances of housing parts and holding units
Solution Approach 1:
A centering unit is introduced as an intermediary component between the hob plate and the user interface element. This centering unit includes a centering element with a centering protrusion that engages with a corresponding centering recess, providing a dedicated centering function that is separate from the housing and holding unit structures, thereby improving positional tolerance without significantly complicating the overall assembly
Solution Approach 2:
The centering function is segmented from the housing and holding unit structures. The centering unit is designed as a separate, dedicated component with specific centering features (protrusion and recess) that independently handle the centering task, allowing each component to be optimized for its specific function and reducing the cumulative effect of manufacturing tolerances
2Productivity
If multiple components (housing, holding unit, centering pins) are used for assembly, then the centering function is provided, but the assembly process is complex and time-consuming with multiple steps
Solution Approach 1:
The centering unit is designed to be integrated with the hob plate as a single assembly unit. The centering element is attached to the hob plate to form a pre-assembled centering unit, which reduces the number of separate components that need to be handled during assembly and simplifies the assembly process by combining the hob plate and centering function into one unit
Solution Approach 2:
The centering unit is pre-assembled and attached to the hob plate before the final assembly with the user interface element. This preliminary action ensures that the centering features are already in place and properly positioned, eliminating the need for complex alignment operations during the final assembly step and thereby improving assembly speed
