Adjustable Shoulder Swing and Chest Press Linkage Machine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fitness equipment often focuses on single body parts, limiting the possibility of users training multiple body parts on the same device, resulting in low training efficiency and the need for frequent equipment changes, which increases training time and space usage.
Innovation Solution
A shoulder swing and chest press combination exercise machine with a frame, adjustment mechanism, movement arm, weight arm, rocker arm, and linkage rod, allowing for adjustable motion trajectories through a rotating disc and plug-in assembly to switch between shoulder swing and chest press modes without tools or complex operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional fixed-motion fitness equipment is used, then the structure is simple and easy to manufacture, but the adaptability is poor and cannot meet personalized training requirements
Solution Approach 1:
The patent implements dynamic adjustability through a rotating disc with multiple positioning holes that can be set to different angles, allowing the motion trajectory to be dynamically changed according to training needs. This transforms the fixed structure into an adjustable one, resolving the contradiction between adaptability and device complexity.
Solution Approach 2:
The exercise machine is designed to perform multiple functions by combining shoulder swing and chest press motions through a universal linkage mechanism. The adjustable rotating disc enables the same device to accommodate different training requirements, achieving multi-functionality without requiring multiple separate equipment pieces.
2Productivity
If single-function exercise equipment is used, then the device complexity is low, but the training efficiency is low due to the need for frequent equipment changes
Solution Approach 1:
The patent merges shoulder swing and chest press functions into a single exercise machine through a unified linkage mechanism. By combining multiple training functions in one device, users can switch between exercises without changing equipment, thereby improving training efficiency while maintaining reasonable device complexity.
Solution Approach 2:
The exercise machine achieves multi-functionality by incorporating both shoulder swing and chest press capabilities through a universal adjustable mechanism. This allows the single device to replace multiple specialized equipment, reducing the need for frequent equipment changes and improving overall training productivity.
3Ease of operation
If fixed motion trajectory equipment is used, then the manufacturing precision requirements are low, but the ease of operation is reduced due to inability to adjust to user needs
Solution Approach 1:
The rotating disc with multiple positioning holes provides dynamic adjustment capability, allowing users to easily change the motion trajectory by simply rotating the disc to different positions. This mechanical adjustment mechanism achieves ease of operation without requiring high manufacturing precision, as the discrete positioning holes guide the adjustment process.
