Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If previously known fixation devices are used to secure electrical devices in installation ducts, then the electrical devices can be fixed in place, but extensive work is required to install and remove the fixation device, and tools are needed for installation
Solution Approach 1:
The fixation device uses a resilient element that can be dynamically compressed to release clamping force, allowing the clamping elements to be easily moved from a clamped state to a released state. This dynamic mechanism enables tool-free installation and removal by simply pressing the resilient element to release the clamps, eliminating the need for extensive manual work and saving time
Solution Approach 2:
The resilient element acts as an intermediary between the user's manual pressure and the clamping elements. By compressing the resilient element, the user indirectly controls the release of multiple clamping elements simultaneously, simplifying the operation and reducing the time required for installation and removal compared to directly manipulating each clamp individually
2Reliability
If previously known fixation devices are used, then the installation duct can be secured, but sufficient friction cannot be achieved to prevent electrical devices from sliding along the opening upon loading
Solution Approach 1:
The fixation device divides the clamping function into multiple independent clamping elements distributed at different locations. Each clamping element independently contacts the installation duct edges, creating multiple friction points. This segmentation of the clamping function increases the total friction force available to prevent sliding, as the combined friction from multiple contact points exceeds that of a single contact point
Solution Approach 2:
The clamping elements are designed with specific local properties including contact surface geometry and material characteristics optimized for friction. Each clamping element has a contact surface configured to maximize frictional resistance at its specific location on the installation duct edge, ensuring reliable prevention of sliding under load
3Reliability
If fixation devices are attached with screws in the installation duct, then secure attachment can be achieved, but some type of tool is required to install the fixation device
Solution Approach 1:
The invention replaces the screw-threaded mechanical fastening system with a direct spring-loaded clamping system. Instead of using screws that require rotational motion and tools, the resilient element provides direct linear compression to engage the clamping elements with the installation duct edges. This substitution eliminates the need for tools while maintaining secure attachment through elastic clamping force
Solution Approach 2:
The resilient element automatically generates and maintains the clamping force without requiring external tools or additional components. The elastic properties of the resilient element enable it to self-generate the necessary force to secure the fixation device to the installation duct, eliminating the need for screw fasteners and tools while ensuring reliable attachment
