Elbow Attachment Tension Line Exercise Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tension line exercise apparatus require users to grasp handles with their hands, limiting the ability to perform activities that need free hands and often cause discomfort due to force application at the hand, which can be problematic for injuries or other conditions.
Innovation Solution
An exercise apparatus with an elbow attachment device and a tensioning device connected to the torso, using elastic sleeves and straps with connectors, allowing resistance to be applied at the elbow without hand grasping, enabling free hands and adjustable resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a tension line exercise apparatus uses handles that must be grasped by hands, then the device can provide resistance for exercise, but the user cannot perform activities requiring free hands and may experience discomfort due to force application at the hand
Solution Approach 1:
The device segments the resistance application point from the hand by introducing an elbow attachment device that applies force directly to the elbow joint, separating the grasping function (handled by minimal or no handles) from the resistance application function (handled by the elbow attachment), thereby enabling hand freedom while maintaining exercise effectiveness
Solution Approach 2:
The elbow attachment device acts as an intermediary between the tension line and the user's body, transferring the resistance force from the hand-held handle to the elbow joint, thus eliminating the need for hand grasping while maintaining the resistance mechanism
2Force
If force is applied at the user's hand through handle grasping, then the tension line can provide exercise resistance, but it causes discomfort for users with hand injuries or pre-existing conditions
Solution Approach 1:
Instead of applying resistance force at the hand (conventional approach), the invention inverts the approach by applying the same resistance force directly at the elbow joint through the elbow attachment device, thereby maintaining the exercise effect while eliminating discomfort associated with hand force application
3Ease of manufacture
If the device requires handle grasping for operation, then the tension line can be actuated, but the user cannot wear boxing gloves or perform other activities requiring free hands
Solution Approach 1:
The invention extracts the essential resistance application function from the handle-grasping mechanism and relocates it to the elbow attachment device, thereby removing the requirement for handle grasping while preserving the core exercise function, enabling compatibility with activities requiring free hands such as wearing boxing gloves
Applied Scientific Principles
