Quick Assembly Knife With Segmented Blade And Handle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional knives with integrated blades and handles incur high transportation costs due to their large size, making them inefficient for export.
Innovation Solution
A knife design that allows for quick assembly and disassembly, featuring a blade with a knife rod and a handle connected via a connection assembly, including a knife clip, knife disc, handle ring, and tie, enabling the blade and handle to be separated during transport and reassembled at the destination, with options for fixation using a tail fixing ring and link rod.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the blade and handle are designed as one piece, then the structural stability is improved, but the transportation cost increases due to large size
Solution Approach 1:
The knife is divided into separate blade and handle components that can be disassembled for transportation. The blade includes a blade body and blade handle, while the full handle is separate, allowing them to be transported independently and assembled at the destination, thereby reducing transportation volume while maintaining structural integrity during use.
2Volume of moving object
If the blade and handle are separated into multiple parts, then the transportation cost is reduced, but the assembly complexity increases
Solution Approach 1:
The knife is segmented into modular components (blade body, blade handle, full handle) that can be easily separated and reassembled.
Solution Approach 2:
The blade handle and full handle are designed to combine through a simple connection structure involving a through hole and fixing mechanism, merging the separate components into a unified functional whole without requiring complex assembly procedures.
3Productivity
If the blade and handle are separated, then the transportation efficiency is improved, but the connection reliability during use may deteriorate
Solution Approach 1:
The knife structure is segmented into separable components for efficient transportation, with the blade and handle designed as distinct modules that can be easily detached and reattached.
Solution Approach 2:
The connection structure utilizes a through hole with a snap-fit mechanism that provides a secure, reliable connection when assembled, ensuring the blade and handle remain firmly connected during use while allowing easy separation for transportation.
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
This design significantly reduces transportation costs and enhances market competitiveness by allowing for easy disassembly and reassembly, while ensuring stability and secure connection of the blade to the handle.
Implementation Method 1
the tie after passing through the rod hole is bound and fixed to the bar
Implementation Method 2
the tail fixing ring is fixed by snap fit at an end of the handle sleeve far away from the built-in sleeve

AI summary
A knife that can be quickly assembled and disassembled comprises a blade and a handle that are removably connected to each other through a connection assembly, and further comprises a knife clip, a knife disc and a handle ring. The left end of the blade is provided with a knife rod. A step is provided at the connection between a main body of the blade and the knife rod. A knife clip is sleeved outside of the step. The handle ring and the knife disc are provided parallel on the left and right sides respectively, and are respectively sleeved outside of the knife rod. The handle comprises a handle sleeve and a built-in sleeve that is fixed at the right end of the inner hole of the handle sleeve.
