Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sports equipment, such as horizontal bars, occupy large spaces, are inconvenient to carry, and lack versatility for different exercises, particularly in household settings where they need to be firmly fixed between narrow surfaces.
Innovation Solution
A multifunctional training handle with a design featuring two pairs of hanging claws, adjustable ring structures, and a lock mechanism, allowing it to be easily mounted on door frames, adaptable to different thicknesses, and convertible for pull-ups, push-ups, and abdominal exercises.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional horizontal bar equipment is used, then exercise stability and safety are improved, but space occupation increases and portability deteriorates
Solution Approach 1:
The horizontal bar is divided into multiple independent components: a door frame mounting structure, a rotating ring assembly, and a handle assembly. These segments can be separately installed on door frames and easily assembled/disassembled, transforming the traditional fixed horizontal bar into a portable multi-functional training device that maintains exercise stability while reducing space occupation.
Solution Approach 2:
The training handle is designed with multiple functions: it can serve as a horizontal bar for pull-ups, as a push-up station, and as an abdominal wheel. The rotating ring assembly allows adjustment between different exercise modes, making a single device replace multiple pieces of equipment and reducing overall space occupation.
2Reliability
If traditional horizontal bar equipment is used, then exercise stability is improved, but portability deteriorates
Solution Approach 1:
The horizontal bar is divided into multiple independent components: a door frame mounting structure, a rotating ring assembly, and a handle assembly. These segments can be separately installed on door frames and easily assembled/disassembled, transforming the traditional fixed horizontal bar into a portable multi-functional training device that maintains exercise stability while reducing space occupation.
Solution Approach 2:
The rotating ring assembly enables dynamic adjustment of the handle position and angle, allowing the same structure to adapt to different exercise requirements. This dynamic capability enhances portability by eliminating the need for multiple fixed devices while maintaining exercise stability through adjustable positioning.
3Device complexity
If single-function horizontal bar equipment is used, then structural simplicity is maintained, but functional versatility deteriorates
Solution Approach 1:
The training handle is designed with multiple functions: it can serve as a horizontal bar for pull-ups, as a push-up station, and as an abdominal wheel. The rotating ring assembly allows adjustment between different exercise modes, making a single device replace multiple pieces of equipment and reducing overall space occupation.
Solution Approach 2:
The rotating ring assembly enables dynamic adjustment of the handle position and angle, allowing the same structure to adapt to different exercise requirements. This dynamic capability enhances portability by eliminating the need for multiple fixed devices while maintaining exercise stability through adjustable positioning.
4Reliability
If fixed horizontal bar equipment is used, then exercise safety is improved, but ease of assembly and storage deteriorates
Solution Approach 1:
The horizontal bar is divided into multiple independent components: a door frame mounting structure, a rotating ring assembly, and a handle assembly. These segments can be separately installed on door frames and easily assembled/disassembled, transforming the traditional fixed horizontal bar into a portable multi-functional training device that maintains exercise stability while reducing space occupation.

AI summary
The present invention relates to a multifunctional training handle, comprising: a first ring assembly, a second ring assembly, four hanging claw assemblies and a handle assembly; wherein the hanging claw assemblies each comprise a claw arm and a claw part that is fixed to a top end of the claw arm, and claw parts of the four hanging claw assemblies are configured to be hung in pairs on top edges of two sides of a door frame in a thickness direction; four hanging claw assemblies are respectively installed on the first ring assembly and the second ring assembly through connecting parts; the first ring assembly and the second ring assembly are assembled, and the second ring assembly has a degree of freedom of coaxial rotation relative to the first ring assembly; and the handle assembly is mounted with the first ring assembly and/or the second ring assembly. The handle can be hung on a door frame for use by using a structure of two pairs of four hanging claws, and is firmly fixed, convenient to disassemble and assemble, saves space, has a small volume and is convenient to carry; in addition, by means of two ring structures that can rotate relative to one another, a distance between the hanging claws may be rapidly adjusted so as to adapt to door frames of different thicknesses; therefore, the handle has abundant functions and high practicability.
