Modular Weight Box Assembly With Vented Threaded Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multifunctional fitness equipment, such as dumbbells, kettlebells, and barbells, face issues with inconvenient installation of threaded sleeves and incomplete ventilation during the solidification process of filling solutions, leading to potential security risks and incomplete assembly.
Innovation Solution
A multifunctional fitness equipment design featuring a weight box with a threaded connection hole, an inner sealing sleeve, and a ring gear structure that allows for gas release through gaps between teeth and grooves, along with a detachable wedge block for easy assembly and secure connection of holding rods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a threaded sleeve is installed into the weight box before the filling solution solidifies, then the multifunctional fitness requirements can be realized, but the filling solution may not be fully infilled and gas may not be completely released
Solution Approach 1:
The threaded sleeve is pre-installed into the weight box before the filling solution is poured in. This preliminary action allows the threaded sleeve to be positioned correctly before the filling solution solidifies, enabling subsequent assembly of holding rods while ensuring proper ventilation during the solidification process.
Solution Approach 2:
The threaded sleeve acts as an intermediary component that facilitates both the ventilation of gas during solidification and the subsequent assembly of holding rods. The threaded sleeve's hollow structure serves as a passage for gas to escape while providing a mounting interface for the holding rods.
2Adaptability or versatility
If the threaded sleeve is installed during the solidification process, then multifunctionality is achieved, but the assembly process becomes inconvenient and may create security risks
Solution Approach 1:
The threaded sleeve is installed in advance before the filling solution solidifies, making the assembly process more convenient. This preliminary installation allows workers to easily secure the threaded sleeve while the filling solution is still pliable, and subsequent assembly of holding rods becomes a simple threading operation rather than a complex installation process.
3Object-generated harmful factors
If ventilation is needed during solidification, then gas can be released, but the filling solution may not be fully infilled
Solution Approach 1:
The threaded sleeve serves as a dual-function intermediary: its hollow interior provides a ventilation passage for gas to escape during solidification, while its threaded structure and positioning ensure that the filling solution can still fully infill the weight box around it. The sleeve's design balances ventilation needs with filling completeness.
