Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical/electronic installation devices are complicated to handle for installation and removal due to their complex structure, requiring tools and multiple steps for fixing and unfixing.
Innovation Solution
The device features automatic locking with window-like openings and latching springs, allowing tool-free installation and easy removal by actuating a single latching mechanism, utilizing a compensating insert for plaster leveling and secure fixation without tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex support assembly with multiple locking mechanisms is used, then the device can be securely fixed in the mounting housing, but the installation and removal process becomes complicated and time-consuming
Solution Approach 1:
The locking mechanism is divided into two independent parts: a first locking device with window-like openings and a second locking device with locking springs. This segmentation allows each component to perform its specific function simply, while together they provide secure fixation. The first locking device prevents lateral displacement and the second prevents removal, achieving reliable fixation through divided functions.
Solution Approach 2:
The locking mechanism is designed to automatically engage when the support assembly is inserted into the mounting housing. The window-like openings and locking springs self-lock without requiring tools or manual intervention, making the installation process simple while maintaining secure fixation. The system serves itself by automatically establishing the locked state upon insertion.
2Strength
If traditional fastening devices like expansion claws or screw connections are used, then the device can be firmly mounted, but tools are required and installation becomes more complex
Solution Approach 1:
The patent replaces traditional mechanical fastening systems (screws, expansion claws) with a spring-based locking mechanism. The locking springs engage with the window-like openings to provide firm mounting without requiring threaded connections or expansion forces. This substitution maintains mounting strength while dramatically simplifying the fastening mechanism.
Solution Approach 2:
The patent extracts the essential locking function from complex fastening systems and implements it through a minimal set of components: window-like openings and locking springs. By taking out only the necessary elements for secure mounting and removing unnecessary complexity, the system achieves firm mounting with a simple device structure.
3Reliability
If multiple locking mechanisms are used to prevent accidental dislodgement, then the device is securely fixed, but the removal process requires multiple steps and actuations
Solution Approach 1:
The two locking devices have asymmetric functions: the first locking device with window-like openings prevents lateral displacement and accidental dislodgement, while the second locking device with locking springs controls the removal process. This asymmetric design provides different levels of restraint for different directions of force, securing the device against accidents while allowing controlled removal through a single actuation of the second locking device.
