Adjustable Overhead Handles for Chin-Dip Exercise Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing assisted chin/dip exercise apparatuses often pose a risk of head injury due to the proximity of overhead handles to the user's head during exercises, particularly when stepping onto the assist bar or performing dip exercises.
Innovation Solution
The apparatus features a pair of adjustable overhead handles that can pivot between two positions, providing sufficient clearance for the head during these actions, with handles that are angled inwardly and rearwardly in one position and extend forward and parallel in another, allowing for safe gripping during chin-ups, pull-ups, and dips, and are freely rotatable to avoid head contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If fixed overhead handles are used for chin-up exercises, then the handles are positioned close to the user's head, but this causes risk of head injury when stepping onto the assist bar or performing dip exercises
Solution Approach 1:
The overhead handles are made dynamically adjustable between at least two positions: a first position close to the overhead support for chin-up exercises, and a second position spaced farther away for dip exercises and when stepping onto the assist bar. This dynamic repositioning eliminates the fixed hazard while preserving exercise functionality.
Solution Approach 2:
The horizontal spacing parameter of the handles relative to the overhead support is changed between exercises. The handles can be positioned at a first horizontal spacing for chin-ups and a second, greater horizontal spacing for dips, allowing optimization of safety and functionality for each exercise type.
2Object-affected harmful factors
If adjustable handles are added to provide head clearance, then head injury risk is reduced, but device complexity increases
Solution Approach 1:
The handles are made dynamically adjustable between at least two positions: a first position close to the overhead support for chin-up exercises, and a second position spaced farther away for dip exercises and when stepping onto the assist bar. This dynamic repositioning eliminates the fixed hazard while preserving exercise functionality.
Solution Approach 2:
The same adjustable handle assembly serves multiple functions: it provides close positioning for chin-up exercises, distant positioning for dip exercises, and intermediate positioning when stepping onto the assist bar. This multi-functionality reduces the need for separate components for different exercise types.
