Detachable Pulley Buckle Assembly for Compact Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wheel designs for household products are predominantly fixed, limiting versatility and efficiency in packaging and transportation due to their non-detachable nature.
Innovation Solution
A portable detachable pulley system is introduced, featuring a gasket with a buckle assembly and a pulley assembly that can be easily assembled and disassembled without tools, allowing for both wheeled and non-wheeled configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If fixed wheel designs are used, then structural stability is improved, but versatility and packaging efficiency deteriorate
Solution Approach 1:
The pulley system is divided into separate detachable components: a gasket with buckle assembly and a pulley assembly with connecting piece. This segmentation allows the pulley to be attached or removed based on usage needs, providing versatility while maintaining structural stability when assembled.
Solution Approach 2:
The design transitions from a static fixed wheel to a dynamic detachable system. The buckle assembly and connecting piece enable the pulley to be easily attached and detached, allowing the system to adapt between wheeled and non-wheeled configurations based on operational requirements.
2Stability of the object's composition
If fixed wheel designs are used, then structural stability is improved, but packaging efficiency and transportation costs worsen
Solution Approach 1:
By segmenting the pulley into detachable components (gasket with buckle assembly and pulley assembly), the system can be packaged in a compact state when the pulley is removed, significantly improving packaging efficiency and reducing transportation costs while maintaining structural stability during use.
Solution Approach 2:
The pulley assembly can be extracted from the gasket when not needed, allowing the main product to be packaged in a more compact form. This extraction capability improves packaging efficiency without compromising the structural stability of the assembled product when the pulley is attached.
3Reliability
If multiple heavy components are used to secure wheels, then reliability of wheel attachment is improved, but overall weight increases
Solution Approach 1:
The traditional heavy mechanical fastening system is replaced with a simplified buckle assembly and connecting piece design. This substitution maintains reliable attachment through the buckle mechanism while significantly reducing the overall weight of the pulley system.
Solution Approach 2:
The attachment mechanism uses a buckle system that achieves reliable wheel attachment with lighter materials and simpler construction. The buckle assembly and connecting piece are designed to provide sufficient attachment reliability without requiring multiple heavy components, thus reducing overall weight.
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 detachable pulley system enhances packaging efficiency, reduces overall weight, and decreases distribution costs by allowing for a more compact design and easy assembly/disassembly.
Implementation Method 1
The upper and lower end faces of the are groove and the upper and lower end faces where the shift block and the are groove are engaged are respectively fixedly embedded with a magnetic insert, and two magnetic inserts distributed facing each other are magnetically attracted to each other. The magnetic insert enhances the stability of the shift block, ensuring its secure positioning at either the upper or lower end of the are groove.

AI summary
A portable detachable pulley is provided, which includes a gasket, and a buckle assembly is provided on the lower end face of the gasket. The buckle assembly includes two symmetrically distributed first buckles fixedly mounted on the lower end face of the gasket, and a second buckle is provided between the two first buckles. The second buckle is located at an end portion of one side of the two first buckles, and a fastening component is provided at the other end portion of the two first buckles. A connecting piece is movably mounted between the first buckle and the second buckle, and a pulley assembly for rolling is provided beneath the connecting piece. The pulley is designed for use both with and without the pulley assembly, depending on circumstances, such that the processes of assembly and disassembly are highly user-friendly and do not necessitate the use of any tools.
