Cooking Hob Housing With Integral Electric Terminal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing induction cooking hobs face challenges in electrical safety and efficient manufacturing, particularly with separate electric terminals and fastening elements that can increase the risk of electrical hazards and complexity in assembly.
Innovation Solution
The integration of electric terminals and double-walled sections within the housing of the cooking hob, which simplifies the assembly of electrical components, enhances electrical safety by isolating fastening elements and reducing the number of parts required, and provides a secure connection for the mains supply cable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate electric terminals are used in the housing, then electrical connections can be made, but the number of parts increases and assembly complexity increases
Solution Approach 1:
The electric terminal is merged with the housing structure itself, forming an integral part of the housing. The housing includes a housing body and an electric terminal that is formed as one piece, eliminating the need for separate electric terminals and reducing the number of parts that need to be assembled together.
2Reliability
If separate electric terminals are used, then electrical connections are possible, but assembly time and manufacturing complexity increase
Solution Approach 1:
The electric terminal is integrated into the housing structure, allowing both components to be manufactured as a single unit. This merging eliminates multiple assembly steps and reduces production time while maintaining electrical safety through the integrated design.
3Ease of manufacture
If fastening elements are not electrically isolated, then assembly is simpler, but electrical safety is compromised
Solution Approach 1:
A non-conductive partition wall is introduced as an intermediary element between the fastening element and the electric terminal. This partition wall electrically isolates the fastening element from the electric terminal, preventing electrical hazards while allowing the fastening element to perform its mechanical function without requiring additional electrical isolation measures.
4Ease of manufacture
If the housing is made fully from plastic material, then manufacturing is simpler and cost-effective, but electrical safety becomes more challenging
Solution Approach 1:
The electric terminal is merged with the plastic housing structure as an integral component. This allows the housing to maintain its fully plastic construction for manufacturing simplicity and cost-effectiveness, while the integrated electric terminal provides the necessary electrical connection functionality with proper safety isolation through the partition wall.
