Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multifunctional fitness equipment, which combines dumbbells, kettlebells, and barbells, faces issues with inconvenient installation of threaded sleeves and incomplete gas release during the solidification process of filling solutions, leading to assembly difficulties and potential safety risks.
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 wedge block mechanism for secure assembly, enabling easy installation and complete ventilation.
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 assembly process becomes inconvenient and gas may not be completely released
Solution Approach 1:
The patent divides the weight box into two main parts: an outer box and an inner box that can be separated. The threaded sleeve is installed on the outer box before filling, while the inner box is filled separately. This segmentation allows the threaded sleeve installation and filling solution solidification to occur independently, eliminating the conflict between these two processes and making the assembly more convenient.
Solution Approach 2:
The threaded sleeve is pre-installed on the outer box before the filling solution is poured into the inner box. This preliminary action ensures that the threaded sleeve is in place before solidification begins, allowing gas to escape during the filling process without interfering with the sleeve installation, thus resolving the assembly inconvenience issue.
2Reliability
If the filling solution is in liquid state during threaded sleeve installation, then ventilation is needed for solidification, but the filling solution may not be fully infilled and gas may not be completely released
Solution Approach 1:
The patent segments the weight box into an outer box and an inner box, allowing the filling solution to be poured into the inner box which is then inserted into the outer box. This segmentation creates a controlled environment for solidification with built-in ventilation pathways through the box walls and gaps, ensuring complete gas release while simplifying the overall assembly process by separating the filling operation from the sleeve installation.
Solution Approach 2:
The inner box acts as an intermediary container during the filling process. It allows the filling solution to be poured and solidified in a controlled manner with adequate ventilation, then inserted as a complete unit into the outer box. This intermediary structure ensures complete gas release during solidification while simplifying the final assembly, reducing the complexity of the overall process.
3Adaptability or versatility
If different fitness equipment are assembled on dumbbells to superimpose functions, then multifunction is achieved, but users cannot experience solely using kettlebells or barbells
Solution Approach 1:
The patent uses a separable design where the inner box containing the filling solution can be removed from the outer box. This allows users to use the outer box as a kettlebell by itself, or insert the inner box to transform it into a dumbbell or barbell. The segmentation enables complete kettlebell experience when the inner box is removed, while still providing multifunctionality when components are combined.
Solution Approach 2:
The patent implements a dynamic, reconfigurable structure where the inner box can be inserted or removed from the outer box based on user needs. This dynamic design allows the equipment to transform between different fitness modes (kettlebell, dumbbell, barbell), providing both complete kettlebell experience and multifunctional capabilities without compromising either aspect.

AI summary
The present disclosure provides a multifunctional fitness equipment, including a weight box, a connection hole provided on one end of the weight box and detachably connected with a holding rod, and a handle provided on a side surface of the weight box or on an end surface away from the connection hole of the weight box. The present disclosure provides a simple structure and is convenient to use. By using the kettlebell as the foundation fitness equipment, the users can obtain complete fitness experience when performing kettlebell fitness training. In addition, by choosing various holding rods to assemble, the functions of the fitness equipment can be changed. It will not interfere the assembled equipment but reserve complete experience when performing the fitness activities of kettlebells, dumbbells, and barbells respectively, therefore has a good experience effect.
