Inflatable Finger Securing Device for Irregular Items
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing securing devices for items during transportation, such as containers, straps, and inflatable bladders, are inadequate as they lack versatility, fail to securely hold fragile or irregularly shaped items, and can cause damage due to shifting or deflation.
Innovation Solution
A securing device with extendable fingers and inflatable arms that use fluid pressure to securely engage items, featuring valve elements to prevent backflow and a compressor to maintain pressure, allowing for customizable fit and secure transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rigid containers are used to secure items, then items are protected from movement, but the device lacks versatility and requires careful packing for items of different shapes
Solution Approach 1:
The securing device is divided into multiple independent inflatable fingers that can be individually adjusted. Each finger can be inflated to different pressures and extents to accommodate items of various shapes and sizes, while collectively providing secure containment without requiring custom packing for each item configuration.
Solution Approach 2:
The device transitions from a static rigid container to a dynamic inflatable structure. The fingers can be inflated or deflated as needed, allowing the device to adapt its shape and volume to match different item configurations. This dynamic adjustment capability provides both versatility for different shapes and reliable security when inflated.
2Adaptability or versatility
If inflatable bladders are used to secure items, then versatility is improved, but the entire system fails if the bag is punctured
Solution Approach 1:
Instead of a single inflatable bladder, the device uses multiple separate inflatable fingers. If one finger is punctured, the others remain inflated and continue to provide securing function. This segmentation isolates the failure impact to a single component while maintaining overall system reliability and security.
Solution Approach 2:
The valve elements are pre-installed in each finger to prevent backflow and control deflation. These valves act as a safety mechanism that maintains pressure integrity even if the finger structure is compromised, providing a backup that preserves security functionality.
3Device complexity
If netting and straps are used to secure items, then the device is simple, but it is difficult to securely hold fragile or irregularly shaped items
Solution Approach 1:
The device uses inflatable fingers that can be filled with air or fluid to create uniform distributing pressure around items. This pneumatic mechanism provides gentle yet secure holding force that adapts to fragile and irregular shapes, overcoming the limitations of simple mechanical straps and netting while maintaining reasonable structural simplicity.
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
The device effectively secures a variety of items by extending fingers or arms to fit snugly around them, preventing damage during transport and allowing for easy retraction when not in use, providing a reliable and adaptable solution for diverse shapes and sizes.
Implementation Method 1
a cavity defined by the interior of the finger that is accessible from the aperture to receive a fluid therein to extend the second end from a first position outwardly from the body to a second position to secure the item
Implementation Method 2
a plurality of valve elements in fluid communication with the aperture to prevent backflow of the fluid from the cavity
Implementation Method 3
a pump in fluid communication with the cavity for providing fluid to the cavity, wherein the plurality of fingers are moveable from a storage position wherein the cavity has a first fluid pressure, to a securing position wherein the cavity has a second fluid pressure greater than the first fluid pressure
