Solution Overview

Problem

Surfboard owners face challenges in transporting surfboards of varying lengths due to the lack of cost-effective, adjustable, and protective carry bags that can accommodate multiple boards securely and compactly, as existing bags offer limited adjustability and compromise on protection and convenience.

Innovation Solution

An adjustable carry bag design featuring end sections that can be coupled and extended with removable sections to accommodate surfboards of different lengths, providing a secure, protective, and compact solution through a coupling structure that encircles the interior space for enhanced protection and flexibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a surfboard carry bag is made longer to accommodate longer surfboards, then it can accommodate more board lengths, but the functional and protective nature of the bag is compromised

Engineering Contradiction:

Improveaccommodation range of board lengthsVSAvoidprotective nature of the bag

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The carry bag is divided into a first section and a second section that can be coupled together. The first section contains a first access opening for board insertion, while the second section contains a second access opening for closure. This segmentation allows the bag to maintain optimal protective characteristics in each section while achieving extended length capability when both sections are coupled together, resolving the contradiction between adaptability and reliability.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If multiple carry bags of varying lengths are purchased to accommodate different surfboard sizes, then all board lengths can be accommodated, but the cost increases

Engineering Contradiction:

Improveaccommodation of multiple board sizesVSAvoidnumber of bags required

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The carry bag system is designed with coupling mechanisms that allow a single bag to function in multiple configurations. By coupling the first and second sections together, the bag can accommodate longer surfboards, while the sections can also be used separately for shorter boards. This multi-functionality eliminates the need to purchase multiple specialized bags, reducing the quantity of equipment required while maintaining versatility across different board sizes.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If a surfboard carry bag is made too long to accommodate longer boards, then it can fit all boards, but the functional nature of the bag is compromised

Engineering Contradiction:

Improvecapability to fit all board lengthsVSAvoidfunctional nature of the bag

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The carry bag employs dynamic coupling mechanisms including zippers and straps that allow the bag structure to be reconfigured. The first and second sections can be coupled together for longer boards or separated for shorter boards. This dynamic adjustability enables the bag to maintain optimal functional characteristics for different board lengths, preventing the bag from being permanently compromised by a fixed oversized design.

Inventive Principle:

Principle #15Dynamics

4Adaptability or versatility

If existing carry bags provide minimal adjustability of approximately 1 foot, then some flexibility is achieved, but the adjustability is insufficient for surfboards with length ranges greater than 1 foot

Engineering Contradiction:

Improvelength adjustability rangeVSAvoidcomplexity of adjustment mechanism

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The carry bag is segmented into a first section and a second section that can be independently configured. The first section contains access opening (105) for board insertion, while the second section contains access opening (120) for closure. This segmentation provides extensive length adjustability for surfboards with ranges greater than 1 foot, while the adjustment mechanism remains relatively simple, involving basic coupling operations rather than complex mechanical systems.

Inventive Principle:

Principle #1Segmentation

AI summary

An adjustable carry bag has two end sections for releasable connection together at connecting ends thereof to form an interior space for accommodating therein at least one sport board. Each end section has a first access opening providing access into the interior space and a closed perimeter portion at the connecting end defining a second access opening providing access into the interior space different from the first access opening. In an open state, the first access opening provide access into the interior space for accommodating therein a sport board. In a closed state of the first access opening when the end sections are connected together, the bag completely encloses and securely holds therein the sport board. A coupling structure extends from the closed perimeter portion of each end section for releasably coupling the end sections together so that the closed perimeter portions and the coupling structures of the end sections encircle a preselected region of the interior space of the bag in both the open and closed states of the first access opening.
