Door Frame Pull-Up Bar With Offset Grip to Prevent Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door frame pull-up bars interfere with the user during exercise, affecting workout effectiveness and posing safety risks.
Innovation Solution
An exercise device with a first gripping member that can be switched between an extended and offset position to avoid interference, featuring a fixing rod, fixing hook, connecting member, and gripping members to ensure user safety and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the first gripping member is positioned in the extended position facing the user, then it provides a comfortable gripping position for exercise, but it interferes with the user during exercise and poses safety risks
Solution Approach 1:
The first gripping member is made movable relative to the connecting member, allowing it to switch between extended and offset positions. This dynamic adjustment enables the gripping member to move from a position that interferes with the user to a position that provides grip comfort, resolving the contradiction between ease of operation and safety
Solution Approach 2:
The first gripping member is positioned in three-dimensional space relative to the reference plane formed by the connecting member and fixing rod. By adjusting its position along different spatial dimensions (extended position with axis perpendicular to reference plane, offset position with axis in reference plane), the design provides grip comfort while avoiding interference with the user's exercise space
2Device complexity
If the first gripping member is fixed in position, then the structure is simple and stable, but it cannot avoid interference with the user during exercise
Solution Approach 1:
The first gripping member is designed with movable connection to the connecting member, enabling it to switch between extended and offset positions. This dynamic capability allows the structure to adapt to different exercise scenarios, avoiding user interference while maintaining relative structural simplicity through straightforward mechanical connection
Solution Approach 2:
The exercise device is divided into separable components: the first gripping member is distinct from the connecting member and can be independently positioned. This segmentation allows the first gripping member to be adjusted to offset position during exercise, avoiding interference while keeping the overall device structure relatively simple

AI summary
An exercise device including a fixing rod, a fixing hook, a connecting member, a first gripping member, and a second gripping member. The fixing rod and the second gripping member are disposed at two ends of the connecting member respectively. The first gripping member is mounted on the connecting member, and the first gripping member is selectively switchable between an extended position and a offset position. When the user grips the first gripping member, the first gripping member is at the extended position for the user to grip. When the user grips the second gripping member, the first gripping member is in the offset position to avoid the first gripping member interfering with an exercise process of the user, providing the user with a better use experience and safety.
