Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional grappling devices are bulky and dirty, causing soilage when stored in boats due to their fixed arms, which become coated with mud, necessitating a compact and cleanable solution.
Innovation Solution
A fold-up grappling device with a telescopic slide bar and foldable arms that can be easily unfolded and folded, allowing for compact storage and easy cleaning, featuring a shank with a hollow tubular shaft and pivotally coupled linking arms to manage the arms' position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the anchor arms are made fixed to maintain structural stability, then the anchoring function is reliable, but the device becomes bulky and difficult to store compactly
Solution Approach 1:
The anchor arms are divided into multiple segments that can fold relative to each other. Each arm consists of a first arm section and a second arm section that can rotate about a fold line, allowing the arms to be segmented into compact configurations for storage while maintaining full arm length and function during deployment.
Solution Approach 2:
The anchor arms transition from a static fixed structure to a dynamic foldable structure. The arms can be rotated between extended positions for anchoring and folded positions for storage, allowing the device to adapt its configuration based on operational needs versus storage requirements.
2Strength
If the anchor arms are made fixed to ensure structural integrity, then the gripping capability is maintained, but the device becomes bulky and occupies excessive space in the boat
Solution Approach 1:
The anchor arms are divided into multiple segments that can fold relative to each other. Each arm consists of a first arm section and a second arm section that can rotate about a fold line, allowing the arms to be segmented into compact configurations for storage while maintaining full arm length and function during deployment.
Solution Approach 2:
The folded arm sections are designed to nest within each other or against the shank structure when in the folded position. The compact configuration allows the arms to be stored within the boat's storage space, similar to nested dolls, while maintaining full structural integrity when extended for use.
3Reliability
If the anchor arms are made fixed to maintain gripping function, then the anchoring reliability is ensured, but the dirty arms soil the boat when stored inside
Solution Approach 1:
The anchor arms are extracted from the boat's internal storage space and placed in an external container or bag for storage. This separation allows the arms to be stored externally where dirt and mud can be contained, preventing them from contacting and soilage the boat's interior surfaces while maintaining full gripping function during deployment.
4Strength
If the anchor arms are made fixed to ensure operational effectiveness, then the gripping capability is maintained, but the device becomes difficult to clean and maintain
Solution Approach 1:
The anchor arms transition from a static fixed structure to a dynamic foldable structure. The arms can be rotated between extended positions for anchoring and folded positions for storage and cleaning, allowing the device to adapt its configuration based on operational needs versus storage and maintenance requirements.
Solution Approach 2:
The anchor arms are extracted from the boat's internal storage space and placed in an external container or bag for storage. This separation allows the arms to be stored externally where dirt and mud can be contained, preventing them from contacting and soilage the boat's interior surfaces while maintaining full gripping function during deployment.
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 compact storage within a bucket or container, preventing soilage and allowing for easy cleaning, while maintaining effective deployment and gripping capabilities with spike members.
Implementation Method 1
A telescopic slide bar (152) is slidably coupled within a hollow tubular shaft member (150) of the shank or crown (105). A plurality of linking arms (130) are coupled to the telescopic slide bar (152) to push the grappling arms (110) to an unfolded position from a folded position or pull the grappling arms (110) to the folded position from the unfolded position.

AI summary
Exemplary embodiments provide a foldable grappling device comprising a shank or crown having a hollow tubular shaft member and a telescopic slide bar slidably coupled within the hollow tubular shaft member. The device further includes a plurality of foldable grappling arms attached to a base of the shank or crown and a plurality of linking arms coupled to the telescopic slide bar to push the grappling arms to an unfolded position from a folded position or pull the grappling arms to the folded position from the unfolded position. Raising the telescopic slide bar within the hollow tubular shaft member unfolds the foldable grappling arms simultaneously and when lowering the telescopic slide bar, the foldable grappling arms are folded simultaneously.
