Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for detachably fastening elements to walls or panels face challenges when incorporating electrically operable components, requiring complex electrical connections and having high installation depths, making them difficult to assemble and disassemble, especially for non-specialists and in applications like shopfitting where aesthetics are important.
Innovation Solution
The device features electrical connection points on the button plate and mating electrical connection points on the rod plate, which automatically align and contact when coupled, allowing for easy power supply to electrically operable components without the need for complex assembly, and can be designed with a low installation depth and attractive appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional electrical connections (cables or plugs) are used for electrically operable components, then power supply is reliable, but assembly is time-consuming and requires specialized knowledge
Solution Approach 1:
The patent combines the mechanical coupling function and electrical connection function into a single integrated fastening device. The coupling means includes both mechanical coupling elements and electrical connection points that are positioned to engage simultaneously when the rod plate is attached to the button plate, eliminating the need for separate cable connections or plug-in operations.
Solution Approach 2:
The device enables automatic electrical connection through its own structure. When the rod plate is mechanically coupled to the button plate using the coupling means, the electrical connection points and counter-connection points are automatically brought into contact, allowing the fastening operation itself to provide both mechanical support and electrical power without requiring additional actions by the operator.
2Ease of operation
If insertion openings are provided for electrical connections, then power supply is achieved, but installation depth becomes large and appearance is compromised
Solution Approach 1:
The patent merges the electrical connection function with the surface-mounted button plate structure. The electrical connection points are positioned on or near the front surface of the button plate, allowing electrical contact to be made at the same location where mechanical coupling occurs, thereby eliminating the need for deep insertion openings behind the panel.
3Ease of operation
If electrical connection points are integrated into the fastening device, then assembly is simplified, but electrical safety risks increase
Solution Approach 1:
The patent introduces an adapter as an intermediary component between the electrical connection points and the rod plate. The adapter provides electrical insulation and safe interface for connection, mediating the electrical contact in a way that protects users from direct exposure to live electrical components while maintaining the simplified assembly process.

AI summary
The invention relates to a device (10) for releasably fastening an element (30) to a wall, to an item of furniture, a column, a wood or glass panel or the like. The device has a rod plate (31) which is disposed on or forms the element (30), wherein the rod plate (31) has at least two claws (32) which form at least one coupling means (33), wherein the claws (32) are designed in particular to be inclined relative to one another. Furthermore a coupling button (13) is provided which can be fastened to a wall and has a button plate (12) and one or more counterpart coupling means (14) which during assembly can be operatively connected to the coupling means (33) of the element (30). For this purpose the plate outline (17) of the button plate (12) has at least one narrowed section (20) which forms a counterpart coupling means (14). The narrowed section (20) divides the button plate (12) into a plate head piece (21) and a plate foot piece (22). According to the invention electrical connection points (40) which can be connected to a voltage source are provided on the button plate (12), in particular in the region of the narrowed section (20). For this purpose the rod plate (31) has counterpart electrical connection points (34) by which electrically operated components which can be mounted on the rod plate (31) can be connected. The electrical connection points (40) and the counterpart electrical connection points (34) are disposed so that in the case of coupling (11) same are brought automatically into a position for effective electrical contact.
