Loop-Shaped Lifting Device with Padded Handle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current lifting devices for moving furniture, mattresses, and appliances are inefficient, uncomfortable, and prone to causing damage or injury due to their design, particularly with traditional hump straps that fray, slip, and require items to be placed on hazardous surfaces, leading to safety and damage concerns.
Innovation Solution
The development of lifting devices featuring an elongated cord with a loop-shaped end and a padded handle, made from durable materials like paracord or nylon, which can be color-coded for size, and a jacket for protection, allowing for easy hooking and lifting of items without them touching the ground, providing comfort and safety through the Hook-N-Flip method.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional hump straps are used to move mattresses and furniture, then the lifting function is achieved, but the straps fray and fall apart over time, and are difficult to place correctly because they slip out of position
Solution Approach 1:
The lifting device is divided into distinct functional segments: a durable loop component for securing the item, a padded handle for user grip, and a connector mechanism. This segmentation allows each part to be optimized independently - the loop provides reliable attachment while the handle ensures comfortable operation, resolving the contradiction between durability and ease of placement.
Solution Approach 2:
The lifting device is designed with pre-formed loops and connectors that are ready for immediate use. The loop is pre-shaped to fit around items like mattresses and furniture legs, eliminating the need for on-site adjustment or complex placement procedures, thus improving both durability and ease of operation.
2Force
If traditional hump straps are used, then lifting function is provided, but they leave imprinted hands and cause loss of circulation, resulting in injury
Solution Approach 1:
The handle portion of the lifting device incorporates padding and ergonomic design specifically at the user-contact area. This local quality improvement maintains the necessary lifting force while preventing hand impressions and circulation loss, thereby reducing user injury and discomfort without compromising lifting capacity.
Solution Approach 2:
The padded handle acts as an intermediary between the user and the lifting mechanism. Instead of the user's hand directly gripping the rough strap material, the padded handle mediates the contact, distributing pressure and eliminating harmful effects while still transmitting the necessary lifting force.
3Ease of operation
If items are placed on the ground for lifting device attachment, then the lifting function is achieved, but the items touch the ground which can cause damage or contamination
Solution Approach 1:
The lifting device enables attachment in a different dimensional approach - instead of placing items on the ground and attaching from above, the loop can be attached from the side or bottom while the item remains elevated. This dimensional change allows the lifting device to be secured without the item touching the ground, preventing damage and contamination while maintaining ease of attachment.
4Force
If traditional lifting methods are used, then moving heavy items is achieved, but the user is left in an unnatural position that puts the back in danger of injury
Solution Approach 1:
The lifting device is designed to be self-sustaining once attached, with the loop and connector mechanisms providing stable support without requiring the user to maintain strained positions. The device serves itself by distributing the weight through its structural design, allowing the user to stand in natural, comfortable positions while still moving heavy items, thereby eliminating back injury risk.
