Self-Adhesive Handle Wrap for Bucket Comfort
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handle designs for heavy buckets, such as those with wire bail handles, are uncomfortable and cause pain due to rigidity, and previous solutions like cushioned pads often fail to securely attach and degrade over time, lacking effective shock absorption and pressure relief.
Innovation Solution
A self-adhesive handle wrap with a reinforcing fabric layer, an elastomer layer for cushioning, and a release sheet for easy application, featuring elongated cutouts and strips for secure fitting and shock absorption, which can be retrofitted onto existing handles without fasteners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a rigid plastic tube is used on the wire bail handle, then the handle structure is simple and inexpensive, but it creates pain and discomfort on the user's hands and fingers when carrying heavy buckets
Solution Approach 1:
The patent applies a flexible foam material layer that conforms to the cylindrical handle shape, providing cushioning and comfort while maintaining structural integrity. This flexible layer replaces the rigid plastic tube's direct contact surface, eliminating pain and discomfort on the user's hands and fingers.
Solution Approach 2:
The patent creates a composite handle structure by combining the rigid cylindrical tube (providing structural support) with a flexible foam material layer (providing comfort and shock absorption). This composite approach maintains the simplicity and low cost of the original handle while eliminating the harmful rigid contact with the user's skin.
2Object-affected harmful factors
If cushioned pads with fasteners are used on the handle, then comfort is improved, but the device becomes bulky and the fasteners may rotate loosely or fail over time
Solution Approach 1:
The patent removes the fastener system entirely from the cushioned pad design. Instead of using snaps, straps, or Velcro fasteners that can fail or rotate loosely, the foam layer is secured through alternative means (such as friction fit, adhesive, or integration with the handle structure), eliminating the bulky and potentially failure-prone fastener components.
Solution Approach 2:
The patent replaces the mechanical fastener system with a non-mechanical attachment method. The foam layer is secured through friction, adhesive bonding, or structural integration rather than mechanical fasteners, reducing device complexity and eliminating the issues of rotation and fastener failure over time.
3Ease of operation
If hooks and loops fasteners are used to secure the pad, then ease of wrapping is improved, but the bonding strength degrades over time as hooks grab debris and loops extend and break
Solution Approach 1:
The patent removes the hooks and loops fastener system from the design. Instead of relying on these fasteners that degrade over time, the pad is secured through alternative means such as friction fit, adhesive bonding, or structural integration with the handle, eliminating the reliability issues associated with hook and loop degradation.
Solution Approach 2:
The patent replaces the mechanical hook and loop fastening system with a non-mechanical attachment method. The pad is secured through friction, adhesive bonding, or structural integration rather than interlocking fasteners, eliminating the problems of hooks grabbing debris and loops extending and breaking over time.
4Ease of manufacture
If the wire bail handle is used without additional cushioning, then the handle remains simple and lightweight, but it causes pain and fatigue when carrying heavy buckets for extended periods
Solution Approach 1:
The patent applies a flexible foam material layer that conforms to the cylindrical handle shape, providing cushioning and comfort while maintaining structural integrity. This flexible layer replaces the rigid plastic tube's direct contact surface, eliminating pain and discomfort on the user's hands and fingers.
Solution Approach 2:
The patent creates a composite handle structure by combining the rigid cylindrical tube (providing structural support) with a flexible foam material layer (providing comfort and shock absorption). This composite approach maintains the simplicity and low cost of the original handle while eliminating the harmful rigid contact with the user's skin.

AI summary
The present invention is related to a self-adhesive cushion laminar for use on handles such as those found on conventional buckets. The self-adhesive laminar includes a fabric layer having an adhesive surface and a non-stick sheet releasably covering the adhesive surface. The self-adhesive laminar is operable for being wrapped around a handle with the adhesive surface overlapping the fabric layer to provide a cushioned handle. The cushion laminar may also include a plurality of elongated cutouts forming a plurality of elongated strips where the cutouts and strips overlap each other to form grooves for receiving the fingers of a user's hand therein when holding onto a covered handle. The cushion laminar includes a variety of different geometrical shapes and sizes.
