Solution Overview
Problem
Current arm exercise equipment is inconvenient to carry, lacks adjustable strength, and poses a risk of injury due to potential dropping during use.
Innovation Solution
An arm exercise machine with a damping-adjustable hydraulic cylinder, upper arm, and forearm assemblies, along with a grip strength assembly and straps for secure fitting, allowing adjustable strength and secure wear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional arm exercise equipment (dumbbells, barbells) is used, then exercise function is provided, but portability is poor and risk of dropping/injury exists
Solution Approach 1:
The exercise equipment is divided into separate modular components including an upper arm component, forearm component, and wrist component that can be independently assembled and disassembled. This segmentation enables easy portability while maintaining exercise functionality, eliminating the need for heavy traditional equipment.
Solution Approach 2:
The patent replaces traditional mechanical weight-based resistance systems with an intelligent control system that uses motors and sensors to provide adjustable resistance. This substitution eliminates heavy weights while maintaining exercise effectiveness, improving portability without compromising reliability.
2Adaptability or versatility
If traditional arm exercise equipment is used, then exercise function is provided, but adjustable strength is limited
Solution Approach 1:
The equipment uses dynamically adjustable motorized resistance systems that can be controlled through a mobile terminal application. Users can adjust exercise parameters including strength levels, repetition counts, and exercise types in real-time, providing high adaptability without requiring multiple physical equipment configurations.
Solution Approach 2:
The modular components can be combined in various configurations to perform different exercises on different body parts. The same upper arm component can work with different forearm and wrist components to create multiple exercise routines, providing universal functionality across different exercise needs.
3Ease of operation
If modular components are used to improve portability, then ease of carrying is improved, but connection reliability may deteriorate
Solution Approach 1:
The modular components are designed with nested structures where smaller components fit within or attach to larger components. The upper arm component contains the forearm component, which in turn contains the wrist component. This nesting approach minimizes the overall size when assembled and ensures secure connections while maintaining portability.
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 convenient carrying, adjustable exercise strength, and prevents injury by ensuring the equipment remains securely attached during use.
Implementation Method 1
a damping-adjustable hydraulic cylinder; when the forearms make an upward lifting action, a certain force is required to be used to lift the forearm under the action of the hydraulic cylinder. Since the damping of the hydraulic cylinder is adjustable
Implementation Method 2
a first spring is further sleeved on the guiding post, and two ends of the first spring are respectively connected to the two gripping handles. When a user holds the gripping handles with his/her hands, the first spring can be pressed tightly through a gripping action, the gripping handles on the two sides are close to each other, and after the gripping handles are released, the first spring separates the gripping handles on the two sides
