Push-up Handle with Ball Joint and Spring Restoring Force
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing push-up handles suffer from uncontrolled tilting and movement, posing a risk of injury due to lack of secure footing and detachment of the handle unit from the support plate, and lack of restoring force to return to a neutral starting position.
Innovation Solution
A push-up handle design featuring a support plate with a handle unit that allows rotational movement and free movement within a predetermined solid angle, secured by a ball joint and rolling bearing, with elastic fastening elements to prevent detachment and return to a neutral position, and a securing element to prevent joint loosening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the handle unit is made movable to allow rotational movement and free movement within a spatial angle, then the ease of operation is improved, but the stability of the object's composition deteriorates due to uncontrolled tipping and movement
Solution Approach 1:
The push-up handle employs a dynamic mounting system that allows controlled movement through a ball joint and rolling bearing, enabling the handle unit to rotate and tilt within predetermined angles while maintaining stability through a spring mechanism that provides restoring force to return the handle to its neutral position
Solution Approach 2:
The patent changes the physical state of the connection between handle unit and support plate from fixed to movable by introducing a ball joint and rolling bearing, allowing the system to transition between stable and mobile states based on operational needs while preventing uncontrolled movement
2Adaptability or versatility
If the handle unit is made movable, then the adaptability is improved, but the reliability deteriorates due to risk of injury from uncontrolled movement
Solution Approach 1:
The dynamic mounting system with ball joint and rolling bearing allows the handle unit to adapt to different user preferences and exercise requirements while the spring mechanism ensures reliable return to neutral position, preventing uncontrolled movement and potential injury
Solution Approach 2:
The spring mechanism acts as a cushioning element that anticipates and counteracts uncontrolled movement by providing restoring force, ensuring the handle unit returns to its neutral starting position and preventing injury from excessive tilting or rotation
3Reliability
If elastic fastening elements are added to prevent detachment, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple functions into the spring mechanism: it serves as both a fastening element to prevent detachment of the handle unit from the support plate and as a restoring force mechanism to return the handle to neutral position, thereby improving reliability without significantly increasing device complexity
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
The design provides a secure and stable training system that prevents uncontrolled movements, ensures shoulder and wrist-friendly exercises, and allows for easy handling and positioning, suitable for various users, including inexperienced ones.
Implementation Method 1
at least one spring which holds the handle unit in a neutral starting position
Implementation Method 2
at least one elastic fastening element which, on the one hand, prevents the handle unit from detaching from the support plate and, on the other hand, returns the handle unit to a neutral starting position
Implementation Method 3
a ball joint which is connected on one side to the support plate and on the other side to the handle unit, wherein the ball joint defines the spatial angle in which the free movement of the handle unit is possible
Implementation Method 4
a rolling bearing which enables the rotational movement of the handle unit, wherein the axis of rotation of the handle unit passes through the longitudinal axis of the ball joint and the pivot point of the ball joint
