Foam Product With Recessed Grip Handle 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 do not provide adequate balance or comfort during carrying.
Innovation Solution
A foam product with a recessed grip handle structure featuring a soft shell made of cross-linked polyethylene foam, integrated into a foam core with a recess that allows finger insertion, providing a comfortable and secure grip, and additional layers such as foam skins and non-foam plastic films for protection and balance.
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 (such as foam rubber or elastic polymer) that covers the rigid grip handle structure. This soft shell conforms to the user's hand shape and allows finger insertion, providing comfort while the underlying rigid structure maintains strength. The soft shell acts as a flexible interface between the rigid handle and the user's hand.
Solution Approach 2:
The patent applies this principle by combining rigid plastic material for structural strength with soft flexible material for comfort. The grip handle structure consists of a rigid core providing strength and a soft outer layer providing comfort during carrying. This composite construction resolves the contradiction by integrating materials with complementary properties.
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 distinct segments: a main body portion and a recessed grip handle portion. The recess is created as a separate segmented feature within the foam core, allowing the grip handle to be formed as a distinct functional zone. This segmentation simplifies the overall structure by creating a clear division between the carrying surface and the grip area.
Solution Approach 2:
The patent applies this principle by pre-forming the recessed grip handle structure during the foam core manufacturing process itself, rather than adding it as a separate component later. The foam core is molded or cut to include the recess and grip handle features as integral parts of the original structure, reducing assembly complexity and integrating the grip function into the basic foam core fabrication.

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.
