Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a plug-socket connection is used between power module and application module, then electrical connection is established, but contact protection is insufficient and installation is complex
Solution Approach 1:
The patent replaces the mechanical plug-socket connection system with a wireless communication interface. The power module and application module communicate via wireless signals, eliminating the need for physical electrical connections between components. This substitution resolves the contradiction by providing complete contact protection (improving reliability) while simplifying installation procedures (reducing device complexity).
Solution Approach 2:
The patent introduces a wireless communication interface as an intermediary between the power module and application module. This intermediary enables energy and data transmission without direct electrical contact, thereby ensuring contact protection while maintaining functional connectivity. The wireless interface acts as a mediator that eliminates the need for complex electrical wiring and plug-socket connections.
2Reliability
If application module is connected via wireless interface, then contact protection is improved, but energy transmission requires additional components
Solution Approach 1:
The wireless communication interface in the patent serves multiple functions simultaneously: it provides contact protection by eliminating electrical contacts, enables data communication between modules, and facilitates energy transmission from the power module to the application module. This multi-functionality resolves the contradiction by avoiding the need for separate components for each function, thereby maintaining contact protection while avoiding additional complexity.
3Adaptability or versatility
If modular design is implemented, then function changes are simplified, but replacement process remains complex
Solution Approach 1:
The patent divides the installation device into separate functional modules: a power module that remains installed in the wall and an application module that can be easily replaced. The application module contains all user-interface components and can be detached and replaced without affecting the power module or requiring electrical work. This segmentation enables simple function changes while maintaining ease of replacement, resolving the contradiction between adaptability and ease of operation.
4Ease of operation
If battery is used in application module, then portability is improved, but maintenance requirements increase
Solution Approach 1:
The patent implements a wireless power transmission system where the power module continuously supplies energy to the application module through the wireless interface. This eliminates the need for a battery in the application module, as the module is self-powered through wireless energy transfer. The system provides continuous power without requiring battery replacement or maintenance, resolving the contradiction between portability and ease of repair.

AI summary
A power module of a modular wall-mounted device has a housing containing one or more electrical connections for connection to the electrical wiring of an electrical installation. The housing also contains electrical and electronic components that can be configured to perform at least one of at least two different functions of a wall-mounted device within an electrical installation. The power module housing also includes a first wireless interface, which is designed to supply an application module, located at a predetermined maximum distance from the power module, with the energy required for its operation. This first wireless interface is also configured for communication between the application module and the power module.The power module is configured to receive control commands from the application module, which configure or parameterize the electrical and electronic components of the power module to implement a function defined by the application module, and control the configured or parameterized function.
