Adjustable Cable Cam Carriage for Versatile Exercise Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exercise equipment lacks adjustability and versatility, failing to accommodate diverse user sizes and workout preferences, limiting the ability to perform a variety of exercises with a single machine.
Innovation Solution
A cable system for exercise machines featuring a cable cam with a carriage that traverses vertically along a post, secured by locking pins, and a cam wheel that creates resistance via a receiving port, allowing for customizable attachments and user supports, with adjustable components to fit user needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If exercise equipment is designed with fixed components, then manufacturing is simpler and device complexity is reduced, but adaptability and versatility are limited
Solution Approach 1:
The cable system employs a movable carriage that can be repositioned along the vertical post to different heights and secured with locking pins. This dynamic adjustment mechanism allows the same equipment to accommodate users of different sizes and perform various exercises, resolving the contradiction between adaptability and device complexity by introducing controlled movability rather than fixed structures
Solution Approach 2:
The cable system is divided into modular components including the carriage, locking pins, cam wheel, and cable assembly. This segmentation allows independent adjustment of each component to suit different exercise requirements while maintaining overall system simplicity, enabling versatility without proportionally increasing complexity
2Ease of operation
If exercise equipment lacks adjustment mechanisms, then device complexity is reduced and ease of manufacture is improved, but ease of operation for diverse users is compromised
Solution Approach 1:
The carriage can be easily moved along the vertical post and locked into position using simple locking pins, allowing users to quickly adjust the cable system for different exercises and body sizes. This dynamic adjustment feature improves ease of operation while maintaining relatively simple device complexity through straightforward mechanical components
Solution Approach 2:
The locking pin mechanism enables users to independently adjust and secure the carriage position without requiring additional tools or complex procedures. This self-service capability enhances ease of operation while keeping the device complexity low through simple user-operable components
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 users to customize workouts by adding various attachments and supports, accommodating different body sizes and exercise movements, providing a comprehensive workout experience.
Implementation Method 1
a cam wheel supported by the carriage, the cam wheel operable via the first attachment to create resistance to the first attachment
Implementation Method 2
a cable supported by the cam wheel and extending from the cam wheel to a cable support system, the cable support system extending the cable to a weight stack; wherein operation of the first attachment operates the cam wheel such that the cable engages the weight stack to create resistance
Implementation Method 3
the carriage configured to traverse vertically along the vertical post and secure at a position via one or more locking pins
