Solution Overview
Problem
Existing household appliances lack flexibility in design and equipment positioning, and there is a need for improved protection against overvoltage and overcurrent issues, as well as effective management of plasma and ions emitted during component failures.
Innovation Solution
A household appliance device with a housing unit and an electronic unit, where a barrier unit is designed separately to delimit the electronic assembly from other components, providing protection through a conductor track assembly and overcurrent protection, and using materials like plastic for the barrier unit to manage plasma and ions, with fastening elements for secure connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the barrier unit is designed separately from the housing unit, then design flexibility and adaptability are improved, but device complexity increases due to additional separate components
Solution Approach 1:
The housing is divided into separate housing units and barrier units that can be independently designed and assembled. The barrier unit is a distinct component from the housing unit, allowing flexible positioning and configuration of electronic assemblies within the housing without requiring redesign of the entire housing structure.
2Reliability
If the barrier unit delimits the electronic assembly from other components, then protection against overvoltage and overcurrent is improved, but the space available for component arrangement is reduced
Solution Approach 1:
The barrier unit acts as an intermediary structure between the electronic assembly and other components. It provides electrical isolation and protection against overvoltage/overcurrent while being designed to minimize space consumption through optimized geometry and integration with the housing unit.
3Object-affected harmful factors
If the barrier unit provides a volume for plasma and ions to spread and dilute, then safety is improved by containing plasma emissions, but the housing space is further reduced
Solution Approach 1:
The barrier unit converts the harmful plasma and ion emissions from the electronic assembly into a contained volume where these emissions can safely spread and dilute. The barrier unit is designed to provide just enough volume for plasma containment while minimizing impact on overall housing space through efficient spatial arrangement.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enhances design flexibility, provides robust protection against overvoltage and overcurrent, effectively contains and dissipates plasma and ions, ensuring increased safety and security while reducing development costs.
Implementation Method 1
In particular, the deposition surface is intended to adsorb ions and/or plasma emitted by the electronic assembly, in particular in the event of a defect

AI summary
The device (12) has an electronic unit (20) arranged in a housing unit, and a barrier unit (50) for delimiting an electronics component e.g. protective component and strip conductor component, of the electronic unit against a major part of other electronic components of the electronic unit in a mounted state. The barrier unit and the housing unit are separately formed from each other. The barrier unit is designed as a partially opened casing in the mounted state and made of plastic. An attachment element i.e. locking element, connects the barrier element with the electronic unit.
