Knife Enclosure Single Fastener Assembly Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current blade enclosures require complex disassembly procedures, often necessitating tools and increasing the risk of accidental harm, especially when cleaning or repairing, due to the use of multiple screws and intricate assembly mechanisms.
Innovation Solution
A blade enclosure design featuring a single fastener with a threaded shaft and guide pins at a non-perpendicular angle, allowing for secure assembly and disassembly without the need for multiple screws, and incorporating a clip for easy blade extension and retraction, facilitating simplified maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple screws and intricate assembly mechanisms are used to secure the blade enclosure, then the enclosure provides strong structural integrity and secure blade storage, but the disassembly procedure becomes complex and time-consuming
Solution Approach 1:
The enclosure is divided into discrete components (first enclosure portion, second enclosure portion, blade) that can be easily separated. The shell is segmented into two portions that can be quickly detached from each other, eliminating the need for complex multi-screw assembly mechanisms while maintaining structural integrity through simple interlocking features.
Solution Approach 2:
The blade is completely extracted from the enclosure for cleaning and maintenance purposes. The design allows the blade to be fully removed from the blade cavity without requiring disassembly of the entire enclosure structure, enabling easy maintenance while the enclosure remains intact.
2Strength
If multiple screws and tools are required for disassembly, then the enclosure can be securely assembled, but the risk of accidental harm increases during maintenance
Solution Approach 1:
The enclosure components are designed to be manually assembled and disassembled without requiring external tools. The first and second enclosure portions can be joined and separated by hand, eliminating the need for screwdrivers or other tools that could cause accidental injury during maintenance operations.
Solution Approach 2:
The blade is completely extracted from the enclosure for cleaning and maintenance purposes. The design allows the blade to be fully removed from the blade cavity without requiring disassembly of the entire enclosure structure, enabling easy maintenance while the enclosure remains intact.
3Stability of the object's composition
If multiple small fasteners such as screws are used in the enclosure assembly, then the structural stability is enhanced, but the manufacturing complexity and assembly difficulty increase
Solution Approach 1:
Multiple fastening functions are merged into a single integrated enclosure structure. The first and second enclosure portions feature complementary joining surfaces that directly engage with each other, eliminating the need for multiple separate fasteners and simplifying both manufacturing and assembly processes while maintaining structural stability.

AI summary
A blade enclosure for selectively releasing and securing a first shell portion and a second shell portion of a shell together with a fastener. The blade enclosure comprises the shell, the fastener and a blade cavity. The shell comprises the first shell portion and the second shell portion. The blade cavity comprises a space between the first shell portion and the second shell portion. The blade enclosure comprises a centerline, a first end and a second end. The fastener is configured to selectively attach to the shell along the centerline. The fastener is configured to further comprise a threaded shaft, and the shell comprises a fastener socket. The fastener socket is partially in the second shell portion and partially in the first shell portion, such that when the shell is in an assembled configuration, the fastener socket is configured hold the first shell portion and the second shell portion together.
