Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sanding tools face limitations in wear resistance, efficiency, versatility, and maneuverability, requiring a solution that allows for easy replacement of abrasive materials and provides a comfortable, cost-effective, and flexible sanding experience.
Innovation Solution
A sanding glove with a permanently attached flexible barrier that supports an abrasive outer layer, allowing for easy replacement and secure attachment, utilizing either adhesive or hook and loop fasteners for efficient sanding operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If abrasive materials are attached directly to the glove outer surface, then the glove is flexible and comfortable, but the glove must be discarded when the abrasive materials wear off
Solution Approach 1:
The sanding glove is divided into separate functional layers: a flexible glove body for comfort and a replaceable abrasive layer for sanding function. This segmentation allows the abrasive layer to be replaced when worn without discarding the entire glove, resolving the contradiction between flexibility and reusability.
Solution Approach 2:
The design allows the abrasive layer to be discarded when worn while recovering and reusing the flexible glove body. The permanent barrier attached to the glove body enables multiple abrasive layer replacements, making the glove reusable and cost-effective.
2Reliability
If a permanent barrier is attached to the glove body, then the abrasive layer can be replaced multiple times, but the structure becomes more complex
Solution Approach 1:
The permanent barrier is integrated directly into the glove body structure, merging the attachment function with the glove fabric itself. This combination approach adds minimal structural complexity while enabling reusable functionality through secure abrasive layer attachment.
3Adaptability or versatility
If the entire gripping face is formed from hook and loop fastener, then abrasive pads can be attached, but the sanding surface does not conform to configuration of a human hand
Solution Approach 1:
The hook and loop fastener is applied locally to specific areas of the glove (palm and finger pads) rather than the entire gripping face. This localized application maintains hand conformity of the glove fabric while providing sufficient attachment areas for abrasive pads in the functional sanding zones.
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 solution enhances the durability and cost-effectiveness of sanding tools by enabling multiple replacements of abrasive layers without tool replacement, improving maneuverability and efficiency in various sanding tasks.
Implementation Method 1
A flexible barrier is positioned between the abrasive outer layer and the glove body. The flexible barrier is permanently attached to the glove body.
Implementation Method 2
The abrasive outer layer releasably attaches to the flexible barrier to facilitate replacement of the abrasive outer layer from the glove body.

AI summary
A glove body, a barrier, and an abrasive layer form a flexible sanding device that fits over the hand of user to perform complex sanding operations on intricate or detailed objects. The glove body includes a palm portion, a plurality of finger portions, and a thumb portion. The finger portions and the thumb portion extend from the palm portion to form a continuous inner surface. The inner surface is covered by the barrier and is coextensive with the abrasive layer. The barrier is permanently attached to the glove body on one surface. The abrasive layer is releasably attached to the opposite surface of the barrier. The barrier is permanently attached to the glove body with a permanent adhesive or through sewing. The abrasive layer is releasably attached to the barrier through a releasable adhesive or through a hook and loop fastener.
