Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing surfboard transport methods, such as cardboard and flexible plastic cases, fail to provide adequate protection against damage and are bulky, making them inconvenient for travel and storage.

Innovation Solution

A collapsible hard case with extension locks and compression latches that allow the case to expand for protection and collapse for storage, featuring a rigid outer surface and adjustable interior lining for various surfboard sizes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a rigid protective case is used for surfboards, then protection against damage during transport is improved, but storage space and portability deteriorate due to large size

Engineering Contradiction:

Improveprotection against damageVSAvoidstorage space

Core Design Contradiction:

ReliabilityVSVolume of moving object

Solution Approach 1:

The case is divided into multiple telescoping sections that can be collapsed into one another, allowing the case to reduce its volume from a large extended state during transport to a compact collapsed state for storage, while maintaining rigid protection when extended

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The case employs telescoping sections with locks that allow dynamic transformation between extended and collapsed states, providing rigidity when needed for protection and compactness when needed for storage

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If a telescoping case structure is used, then storage convenience is improved, but structural strength deteriorates due to moving parts

Engineering Contradiction:

Improvestorage convenienceVSAvoidstructural strength

Core Design Contradiction:

Ease of operationVSStrength

Solution Approach 1:

The case includes lock mechanisms that are engaged before transport to secure the telescoping sections in their extended position, ensuring structural strength is restored before the object is placed in the case for transport

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The telescoping sections are designed with reinforcement elements and locking mechanisms at each segment interface to maintain structural integrity while allowing collapse for storage

Inventive Principle:

Principle #1Segmentation

AI summary

A protective case for large objects including a lock housing formed from a first section and a second section, both of the sections including at least one external subsection and at least one internal subsection configured to telescope inside the external subsection; and an extension lock comprising a lock housing and a compression lock, the lock housing including a screw-threaded channel, and the compression comprising at least one screw-threaded shaft with a compressive component on the interior end and a lock handle on the exterior end, the screw-threaded shaft configured to matingly engage with the screw-threaded channel of the lock housing; the compression lock configured to descend in the lock housing and compressingly lock the internal subsection in an extended position upon locking rotation of the compression lock; and the compression lock configure to ascend in the lock housing upon unlocking rotation of the cam latch.
