Foldable Exercise Device with Rotating Hooks and Parallel Handles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional door mount exercise devices are bulky and difficult to store, and they do not provide parallel chin-up bars for neutral grip chin-ups, making them unsuitable for small spaces.
Innovation Solution
A foldable exercise device with a chin-up apparatus and a dip exercise apparatus that can be suspended from the chin-up apparatus, featuring rotating door header hooks and parallel chin-up handles that convert from a flat configuration to an exercise configuration, allowing for neutral chin-ups and dip exercises, and include biasing mechanisms to maintain the exercise configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the exercise device is designed to be foldable for compact storage, then the storage space requirement is reduced, but the structural complexity increases
Solution Approach 1:
The exercise device is divided into multiple independent components: top horizontal member, bottom horizontal member, connecting members with rotating door header hooks, and dip exercise apparatus. These segmented components can be folded and stored separately, reducing overall storage space while maintaining functional integrity during use.
Solution Approach 2:
The connecting members incorporate rotating door header hooks that can dynamically transition between exercise configuration (engaged with door frame) and storage configuration (folded flat). This dynamic capability allows the device to adapt its form factor based on operational needs, enabling compact storage without permanent structural compromise.
2Adaptability or versatility
If parallel chin-up bars are added for neutral grip chin-ups, then the exercise functionality is improved, but the device complexity increases
Solution Approach 1:
The connecting members serve multiple functions: they provide structural support, enable door frame engagement via door header hooks, and provide parallel chin-up handles for neutral grip exercises. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity while enhancing exercise versatility.
Solution Approach 2:
The parallel chin-up handles are integrated into the connecting members rather than being separate attachments. This merging of functions allows the same structural element to provide both support and exercise functionality, reducing overall device complexity while adding neutral grip capability.
3Volume of moving object
If the device is made compact for small spaces, then the storage requirement is reduced, but the exercise capability may be limited
Solution Approach 1:
The device transitions from a compact folded state to a fully extended exercise configuration when needed. The rotating door header hooks and foldable connecting members enable this dynamic transformation, ensuring that the compact storage form does not permanently limit exercise capability.
Solution Approach 2:
The dip exercise apparatus and chin-up apparatus are designed to nest together when folded, with smaller components fitting within or alongside larger structural elements. This nesting minimizes storage volume while preserving all exercise functions when the device is deployed.
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
Enables users to perform neutral chin-ups and dip exercises while allowing for compact storage by converting the device from an exercise configuration to a flat configuration, suitable for small spaces.
Implementation Method 1
Passing through the slot in the tube is a first pin that pushes on the sleeve. Pushing on the first pin is a spring that is inside the tube.
Implementation Method 2
Each connecting member has a door header hook and a parallel chin-up handle that rotate on the connecting member from a flat configuration to an exercise configuration.
Implementation Method 3
the bottom horizontal member contacting the front side of the door frame by pressing against the vertical door jams of the door frame

AI summary
A foldable exercise device with a chin-up exercise apparatus and a dip exercise apparatus suspendable from the chin-up exercise apparatus. The chin-up exercise apparatus has a top horizontal member and a bottom horizontal member connected by two connecting members. Each connecting member has a door header hook and a parallel chin-up handle that rotate on the connecting member from a flat configuration to an exercise configuration. In the exercise configuration the chin-up exercise apparatus can engage a door frame. In the exercise configuration the parallel chin-up handles can be used for neutral chin-ups. The dip exercise apparatus has two vertical members spaced apart by a horizontal connecting member. The vertical members have a bottom end with a bottom grip. The bottom grip can be rotated from a flat configuration to an exercise configuration. In the exercise configuration the bottom grips can be used to do dip exercises.
