Wallbox Dimmer Structure for Modular Buttons and Stable Wireless Range
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless wallbox dimmers have non-interchangeable components, requiring different button configurations and internal components, which limits versatility and increases manufacturing complexity. Additionally, these dimmers are prone to yoke warping during installation, causing button malfunction, and typically can only house one or two semiconductor power devices.
Innovation Solution
A load control device with a universal structure that accommodates multiple button configurations and a variable number of semiconductor power devices, featuring a metal yoke with a cradle that supports the button assembly independently, and a two-loop antenna for enhanced wireless communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different button configurations are used in wallbox dimmers, then diverse functionality is achieved, but device complexity and manufacturing complexity increase due to non-interchangeable internal components
Solution Approach 1:
The patent implements a universal internal component design where a single yoke, antenna, and circuit board assembly can support multiple button configurations (single button, dual button, rotary dial, touch interface). The standardized mounting structures and spatial arrangements allow these components to work with various button assemblies without modification, enabling one internal component set to serve multiple functional configurations.
Solution Approach 2:
The patent separates the button assembly from the internal components, allowing the button interface to be independently configured while the core internal components (yoke, antenna, circuit board) remain standardized. This segmentation enables different button configurations to be implemented as separate, interchangeable modules that interface with the same underlying hardware platform.
2Device complexity
If button assembly is directly supported by the yoke, then structural simplicity is achieved, but reliability decreases due to yoke warping during installation
Solution Approach 1:
The patent introduces a dedicated button assembly support structure that acts as an intermediary between the button assembly and the yoke. This separate support structure bears the mechanical load of the button assembly, isolating it from the yoke's warping and distortion during installation and operation. The support structure may include mounting brackets, spacers, or reinforcement elements that provide stable attachment points for the button assembly independent of the yoke's structural integrity.
3Device complexity
If only one or two semiconductor power devices are housed in the dimmer, then device simplicity is maintained, but adaptability decreases for higher power applications
Solution Approach 1:
The patent implements a dynamic and scalable semiconductor device configuration where the number and arrangement of power devices can be adapted based on application requirements. The internal component layout, including heat sink arrangements and electrical connection points, is designed to accommodate one, two, or multiple semiconductor devices in series or parallel configurations, allowing the same physical platform to handle varying power levels from low-power residential to high-power commercial applications.

AI summary
A provided wireless wallbox dimmer may accommodate a plurality of button configurations. The dimmer may be configured to contain a variable number of controllably conductive devices. The dimmer may include a yoke that defines a first plane and an antenna that defines a second plane that is substantially parallel to and spaced apart from the first plane. The yoke may have a flange that is oriented angularly offset relative to the first plane and provides a plurality of mounting locations for controllably conductive devices. The antenna may provide the dimmer with a first wireless transmission range. The dimmer may include a faceplate that cooperates with the antenna to provide the dimmer with a second wireless transmission range that is broader than the first wireless transmission range. The dimmer may include a button assembly that is supported independently of the yoke.
