Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Many existing device mount solutions for electrical installation devices on cable routing ducts require complex assembly processes or tools, often necessitating additional screwing for a firm hold, which is unsatisfactory.
Innovation Solution
A device carrier with a base part, side parts, and mounting columns, featuring a closure element with a base plate, guide tongues, and a rear strip forming a guide slot for quick-release fastening, allowing one-handed assembly without additional tools, and optionally including fastening pins and screw columns for additional security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional fastening methods (screws, snap fasteners) are used to attach electrical installation devices to device mounts, then firm holding strength is achieved, but assembly complexity increases and tools are required
Solution Approach 1:
The patent replaces traditional mechanical fastening systems (screws, snap fasteners requiring tools) with a friction-based mechanical insertion system. The electrical installation device is secured through friction between the device and the mounting structure, eliminating the need for additional fastening components and tools while maintaining firm holding strength.
Solution Approach 2:
The patent extracts and eliminates unnecessary fastening components (screws, snap fasteners, additional mounting elements) from the assembly system. By removing these extra components and relying on the inherent friction of the insertion-fit design, the patent simplifies the overall device structure and assembly process while achieving adequate holding strength.
2Reliability
If additional screw connections are used to ensure firm fastening, then reliability of attachment is improved, but assembly time and process complexity increase
Solution Approach 1:
The patent substitutes multi-step mechanical fastening operations (drilling, screwing, tightening) with a single friction-based insertion operation. The friction between the inserted device and mounting structure provides sufficient attachment reliability without requiring additional time-consuming screw connections.
Solution Approach 2:
The mounting structure utilizes the friction generated during the insertion process itself to achieve secure attachment. The act of inserting the device creates the friction force needed for reliable fastening, eliminating the need for separate fastening steps and reducing assembly time.
3Reliability
If multiple fastening components and tools are required for assembly, then secure fastening is achieved, but ease of operation deteriorates
Solution Approach 1:
The patent replaces complex multi-component fastening systems requiring various tools with a simple friction-based insertion mechanism. This allows secure fastening to be achieved through a single hand operation without requiring additional tools or multiple fastening components.
Solution Approach 2:
The patent removes unnecessary fastening components (multiple screws, snap fasteners, mounting brackets) and tools from the assembly process. By relying on friction alone, the system achieves secure fastening with minimal components, dramatically improving ease of operation.

AI summary
The carrier has a base part (2) receiving an electrical installation device. Closure elements (10) fasten the device or a mounting part of the device at the base part in quick-release manner. The closure elements include a base plate (12) and a rear strip (16), which defines a guide slot (15) together with the plate for receiving the device or the mounting part. Fastening pins (11) are designed at lower side of the plate and engaged with openings (6) of mounting columns (5) of the base part in mounting condition, and fix the closure elements at the base part.
