Solution Overview
Problem
Conventional exercise apparatus are often large, cumbersome, and space-consuming, making them unsuitable for modern homes where space is limited, and require maintenance, which is inconvenient.
Innovation Solution
A compact, lightweight hand-held exercise apparatus made of glass-filled nylon with thermoplastic elastomer handles, featuring a rigid frame with rotating sleeves for comfortable grip and easy assembly, designed to strengthen upper body muscles without the need for maintenance or extensive space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If conventional exercise apparatus are used, then exercise effectiveness is achieved, but the apparatus become large, cumbersome and space-consuming
Solution Approach 1:
The apparatus is divided into five separate struts (three first struts and two second struts) that can be independently manufactured and assembled. This segmentation allows each component to be optimized for minimal size while maintaining the overall structural integrity needed for effective exercise, resolving the contradiction between compact size and exercise effectiveness.
Solution Approach 2:
The patent employs composite materials including glass-filled nylon for the rigid frame struts and thermoplastic elastomer for the rotating sleeves. This composite approach enables the apparatus to achieve both compact dimensions and sufficient structural strength for effective muscle strengthening, addressing the volume-effectiveness contradiction.
2Ease of operation
If conventional exercise apparatus are used, then exercise effectiveness is achieved, but maintenance requirements increase
Solution Approach 1:
The apparatus is designed as a self-contained unit with no external power sources, motors, or complex mechanical systems that would require maintenance. The simple strut-based structure with rotating sleeves requires no maintenance, aligning with the self-service principle and eliminating maintenance requirements while preserving exercise effectiveness.
3Ease of operation
If conventional exercise apparatus are used, then muscle strengthening is achieved, but space occupation increases
Solution Approach 1:
The apparatus transitions from traditional three-dimensional bulky structures to a two-dimensional flat configuration when not in use. The struts are arranged in a planar geometry that can be collapsed or stored in a compact form, occupying minimal space while maintaining the three-dimensional exercise capabilities needed for muscle strengthening during use.
4Strength
If rigid handles are used, then grip strength is improved, but comfort of grip decreases
Solution Approach 1:
The handles are designed as rotating sleeves made from thermoplastic elastomer that can rotate freely on the rigid strut spindles. This dynamic rotation allows the handle to adapt to the user's hand shape and provide comfortable grip, while the inner rigid spindle maintains structural strength for effective exercise, resolving the contradiction between grip comfort and strength.
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
Enables effective upper body exercises in a small area without cluttering living or gym spaces, providing a durable and efficient training solution for muscle strengthening with minimal space requirements.
Implementation Method 1
The two outer vertical struts are covered with a rotatable sleeve each. These sleeves are molded from a thermoplastic elastomer, providing the user with a comfortable feeling of softness on their outside, but still keeping shape as to not interfere with the rotatable nature of the grip.
Implementation Method 2
The apparatus is molded in glass filled nylon and the handles are made from thermoplastic elastomers. The main body is rigid
