Multifunctional Training Handle with Adjustable Door-Frame Claws
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sports equipment, such as horizontal bars, occupy large spaces, are inconvenient to carry, and have limited functionality, making them unsuitable for household use and requiring firm fixation to prevent accidents during pull-ups.
Innovation Solution
A multifunctional training handle with a design featuring two pairs of hanging claws that can be adjusted to fit different door frame thicknesses, allowing for pull-ups, push-ups, and abdominal wheel exercises, and includes a hollow circular tube for versatility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional horizontal bar equipment is used, then pull-up function is provided, but space occupation is large and portability is poor
Solution Approach 1:
The horizontal bar is divided into multiple segments that can be folded and collapsed. The bar consists of at least two bar sections that can be rotated relative to each other, allowing the structure to be compacted into a small volume for storage and transport, while still providing full functionality when deployed.
Solution Approach 2:
The bar sections are designed to nest within each other when collapsed, with inner bar sections fitting inside outer sections. This nesting arrangement minimizes the overall volume when the equipment is not in use, dramatically reducing space occupation while maintaining full bar length functionality when needed.
2Ease of operation
If traditional horizontal bar equipment is used, then pull-up function is provided, but device complexity for fixation is high
Solution Approach 1:
The bar incorporates dynamic adjustment mechanisms that allow the width and height of the bar to be easily changed by rotating sections relative to each other. This enables the equipment to adapt to different door frame dimensions without requiring complex fixation systems, as the bar can be configured to fit various openings using simple rotational movements.
Solution Approach 2:
The bar is designed with universal adaptability to fit different door frame sizes and configurations. By incorporating adjustable sections that can be rotated to various angles, the bar can accommodate a wide range of openings, eliminating the need for multiple specialized fixtures or complex installation procedures for different door sizes.
3Reliability
If fixed horizontal bar equipment is used, then safety during pull-up is ensured, but portability and space saving are compromised
Solution Approach 1:
The bar includes preliminary safety features such as locking mechanisms that automatically engage when the bar is properly installed. The rotational sections can be locked into position using simple latch mechanisms that provide secure fixation before use, ensuring safety is established in advance without requiring heavy permanent installation or complex assembly procedures.
