Crossbar Functional Trainer Two-Dimensional Handle Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing resistance training machines lack the ability to provide a two-dimensional plane of handle placement, limiting user flexibility and ergonomics, as they primarily offer vertical or linear options rather than adjustable horizontal and vertical positions.
Innovation Solution
The Crossbar Functional Trainer introduces a system where a crossbar mounted on a carriage can slide along a column, allowing the crossbar to be positioned in a plane that spans both horizontally and vertically, enabling users to access handles at various distances and heights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a vertical carriage system with fixed locking positions is used, then the structure is simple and easy to manufacture, but the user has limited access positions and cannot adjust handles in a two-dimensional plane
Solution Approach 1:
The patent transitions from a one-dimensional vertical carriage system to a two-dimensional system by adding a crossbar that extends horizontally from the carriage. This allows handles to be positioned both vertically (via carriage movement) and horizontally (via crossbar adjustment), creating a plane of movement that significantly increases exercise versatility and user adaptability.
Solution Approach 2:
The system is divided into separate functional components: a vertical carriage for height adjustment, a horizontal crossbar for width adjustment, and independent cable paths for each dimension. This segmentation allows each component to perform its specific function while working together to provide two-dimensional handle placement options.
2Ease of operation
If a two-dimensional crossbar system is added to provide horizontal and vertical adjustment, then user ergonomics and exercise options improve, but the device complexity and number of parts increase
Solution Approach 1:
The crossbar serves multiple functions: it provides horizontal positioning for handles, supports cable paths for both horizontal and vertical cable routes, and acts as a mounting structure for pulleys and rollers. This multi-functionality reduces the need for separate components, thereby limiting the increase in overall system complexity despite the added two-dimensional capability.
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
This solution enhances user ergonomics by allowing for a wider range of exercise options within a two-dimensional plane, improving adjustability and accommodating users of different sizes and exercise preferences.
Implementation Method 1
Pulleys connected to the slidable carriage surrounding the column... cables (connected to form two or more circles from the resistance to the protruding ends to be pulled by the user)
Implementation Method 2
resistance feature, such as a weight stack... The Bar Functional Trainer is an exercise machine that uses cables... to be pulled by the user

AI summary
The Crossbar Functional Trainer is a functional trainer, the Crossbar Functional Trainer is an exercise machine that uses cables (connected to form two or more circles from the resistance to the protruding ends to be pulled by the user) and a resistance feature, such as a weight stack, to allow a crossbar mounted (to a carriage) to a column at a perpendicular angle, and slidable along the same column by way of a carriage and pin, to allow one or both or more cables protruding from it to be pulled by the user, the pulling of the cables shrinks the circles one, or both, or others, at a time to act with force with the resistance feature to create resistance, such as lifting the weight stack, The crossbar has a slit from the ends, to close to the center, on each side, The bars' main feature is that the protruding cables are separated into half the bar each and mirror each other in use, each cable protruding is affixed with a stopper and then a carabiner, the stopper and carabiner are movable along the bar from close to the center to the end by means of a sliding mounted plate over the slit that has a hole for the cable, and rollers on the hole to protect the cable, The sliding mounted plates are connected to the bar also by a pin and hole each and a series of holes along the top or bottom of the bar, which align for use at many points, The mounted carriage on the column which has a shape to surround or connect to the column (around the column) also has rollers to slide along the column and holes on the column and a hole and pin on the bar connected to the carriage to align to mount the column at many points.
