Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional fastening methods for server cabinets are inefficient, complex, and cumbersome, requiring welding and dedicated buckle accessories, making maintenance and disassembly difficult and unreliable.
Innovation Solution
A fastener comprising an upper limit member, fastening spring, and fastening pin rod with specific structural features such as limit holes, rotation grooves, and anti-rotation limiters, allowing for interference and clearance fits, enabling easy assembly and disassembly without dedicated buckles, and made from a combination of plastic and metal materials for improved wear resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fastening methods are used, then the fastening is stable and reliable, but the structure becomes complex and requires dedicated buckle accessories
Solution Approach 1:
The patent merges the fastening function and the buckle function into a single integrated fastener assembly. The pin rod with spring mechanism combines the fastening action with the locking/buckling action, eliminating the need for separate buckle accessories while maintaining fastening reliability
Solution Approach 2:
The fastener is designed as a universal component that can be used for multiple fastening applications without requiring dedicated buckles for each specific case. The spring-loaded pin mechanism provides both fastening and locking functions in a single universal device
2Strength
If traditional fastening methods are used, then the fastening is strong, but the disassembly and assembly become cumbersome
Solution Approach 1:
The fastener incorporates a dynamic spring mechanism that allows the pin rod to be easily inserted and locked into position. The spring provides automatic engagement and locking, making assembly simple while maintaining strong fastening. Disassembly is equally simple by applying force to release the spring-loaded locking mechanism
3Reliability
If welding or other manufacturing processes are used, then the fastening is reliable, but the manufacturing process becomes more complex
Solution Approach 1:
The fastener is divided into separate modular components: the pin rod, the spring, and the housing with limit members. These segmented parts can be manufactured independently using standard machining processes without requiring welding or complex manufacturing operations, then assembled together to form the complete fastening device
4Reliability
If large volume fasteners are used, then the fastening is reliable, but the fastener becomes unsuitable for narrow spaces
Solution Approach 1:
The spring mechanism is nested within the pin rod assembly, and the limit members are integrated into the housing structure. This nested arrangement allows the fastener to maintain its reliable spring-loaded locking mechanism while minimizing the overall volume, making it suitable for installation in narrow spaces
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The fastener is compact, reliable, and suitable for narrow spaces, allowing for quick and easy fastening or unfastening by rotating 90°, facilitating maintenance and replacement, and accommodating varying plate thicknesses due to the compression spring's action.
Implementation Method 1
a lower end of the fastening spring supports and touches a bottom inner end face of the lower limit member
Implementation Method 2
The pin head of the fastening pin rod is installed in the limit hole of the upper limit member to form an upper component through interference fit
