Plastic Base Support Layout for Appliance Wireless Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication modules in domestic appliances are often shielded by metal parts, limiting their range and making installation in different variants complex, especially in built-in appliances where additional logistical costs and complexity arise.
Innovation Solution
A communication module is positioned within a plastic base support with minimal shielding, allowing for wide range wireless communication and easy installation across various appliance variants by being enclosed on all sides or positioned between a front wall and reinforcing rib, and optionally embedded in damping material for vibration isolation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the communication module is integrated into a front panel, then it can be installed in different variants, but it is shielded by metal parts which limits the range
Solution Approach 1:
The communication module is extracted from the front panel and relocated to the base support, removing it from the metal shielding environment while maintaining installation flexibility across different appliance variants
Solution Approach 2:
The base support acts as an intermediary structure that provides a non-metallic mounting location for the communication module, mediating between the need for versatile installation and the requirement for minimal electromagnetic shielding
2Object-affected harmful factors
If the communication module is relocated to avoid shielding, then the range is improved, but the installation complexity increases in built-in appliances
Solution Approach 1:
The base support is designed as a universal component present in all appliance variants, allowing the communication module to be installed in the same location across different models including built-in appliances, thereby reducing installation complexity while maintaining low shielding
3Object-affected harmful factors
If the base support is made of plastic, then the communication module is less shielded, but the structural strength may be reduced
Solution Approach 1:
The base support uses composite construction combining plastic material with integrated reinforcing ribs, achieving both electromagnetic permeability for the communication module and sufficient structural strength for supporting the appliance
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 provides a communication module with a wide range and simplified installation across different appliance variants, reducing logistical costs and enhancing service life through reduced shielding and vibration isolation.
Implementation Method 1
the base support is at least partially permeable to electromagnetic radiation, such that the communication module is only slightly shielded
Implementation Method 2
the communication module is disposed on or in a damping material. This means that the communication module can be isolated from vibrations of the domestic appliance

AI summary
A domestic appliance includes a housing, a base support configured to support the housing on a floor, and a communication module configured to send and/or receive data wirelessly. The communication module is disposed within the base support, with the base support being made of plastic, at least in an area adjacent to the communication module.
