Foam Grip Handle With Soft Shell For Paddle Board Carrying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional foam products for carrying wide items like standup paddle boards lack a comfortable and secure grip handle structure, often relying on rigid materials that may not provide adequate balance or comfort during carrying.
Innovation Solution
A foam product design featuring a recessed grip handle with a soft shell made of cross-linked polyethylene foam, integrated into a foam core with a bubbly texture, allowing for finger insertion and providing a secure grip, combined with a layered structure of foam skins and non-foam plastic films for enhanced durability and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid plastic material grip handle structure is used, then structural strength is improved, but comfort and ease of operation deteriorate
Solution Approach 1:
The patent applies this principle by using a soft shell made of flexible material that conforms to the hand shape, providing comfort while maintaining structural integrity through its integration with the rigid foam core
Solution Approach 2:
The patent applies this principle by combining rigid foam core material with a soft flexible shell material to create a composite grip handle structure that simultaneously provides strength and comfort
2Ease of operation
If a recessed grip handle structure is created, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent applies this principle by dividing the foam core into segments, with a recessed portion created to accommodate the soft shell, forming an integrated but structurally simple grip handle

AI summary
A foam product includes a foam core, a soft skin covering the foam core, and a base structure on which the foam core is disposed. The foam core of expanded beads has an outer surface on which some outermost beads of the expanded beads are exposed and bulging outward with different heights to form a bubbly texture. The foam skin has an inner surface attached to the outer surface of the foam core, and has at its inner surface a plurality of concave cavities each matedly surrounding a respective one of the bulging, outermost beads on the outer surface of the foam core.
