Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Induction hobs integrated into worktops face risks of mechanical and liquid stress due to thin worktops, potentially exposing sensitive electronics to damage from leaks or mechanical stress, compromising safe operation.
Innovation Solution
A fully integrated hob module with a carrier device designed as a liquid-tight separating device, where the induction device is above and the generator device is below, protected by a metal plate, with strain relief lines and cable bushings to prevent liquid ingress and mechanical stress, ensuring safe operation even if the worktop is defective.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the worktop is made thin to achieve a sleek integrated design, then the aesthetic appearance and integration are improved, but the worktop becomes more susceptible to defects and liquid penetration
Solution Approach 1:
The support structure is divided into a first support region (carrying induction units) and a second support region (carrying generator unit), separated by a liquid-tight separating device. This segmentation allows the thin worktop to maintain aesthetic integration while the separating device prevents liquid penetration to sensitive components below.
Solution Approach 2:
A liquid-tight separating device is introduced as an intermediary element between the induction units and the generator unit. This mediator prevents liquid that penetrates through the thin worktop from reaching the generator unit, thus protecting sensitive electronics while maintaining the overall integrated design.
2Device complexity
If the generator unit is placed directly below the worktop for compact integration, then space utilization is improved, but the sensitive electronics are exposed to liquid and mechanical stress
Solution Approach 1:
The support structure is segmented into distinct regions: a first support region directly below the worktop carrying induction units, and a second support region carrying the generator unit. The liquid-tight separating device creates a barrier between these regions, allowing compact vertical integration while protecting the generator unit from liquid exposure.
Solution Approach 2:
The liquid-tight separating device acts as an intermediary barrier between the worktop area (where liquids may penetrate) and the generator unit (sensitive electronics). This mediator enables compact placement of the generator unit below the worktop while preventing harmful liquid contact.
3Device complexity
If cables are routed directly from induction units to generator unit for simplicity, then connection complexity is reduced, but cables are exposed to mechanical stress and liquid ingress
Solution Approach 1:
Cables are routed through a cable guide structure that changes their spatial path, directing them away from areas of high mechanical stress and liquid exposure. The cable guide provides a protected pathway that maintains connection simplicity while enhancing cable durability through improved routing geometry.
