Rack for sport boards
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for storing sport boards lack portability and ease of assembly/disassembly, often requiring tools and occupying excessive space.
Innovation Solution
A modular rack system that can be connected to a wall, featuring a casing with sliding drawers to store arms, allowing for tool-free assembly and disassembly, and compact storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a rack is designed to be disassembled and assembled without tools or screws, then ease of operation is improved, but reliability may worsen due to potential instability of tool-free connections
Solution Approach 1:
The rack is divided into modular components (base, vertical support, arms) that can be independently assembled and disassembled. Each component features standardized connection interfaces that enable tool-free assembly while maintaining structural integrity through precise geometric fitting.
Solution Approach 2:
The arms are designed to be stored within the base structure when not in use, creating a compact nested configuration. This nesting mechanism also serves as part of the connection system, where the arms slide into receptacles on the base, providing both storage and structural attachment without requiring additional fasteners.
2Ease of operation
If the rack is designed to store parts in a drawer contained in the base, then ease of operation is improved for portability, but device complexity worsens due to additional drawer mechanism
Solution Approach 1:
The drawer mechanism is integrated with the base structure, combining storage functionality with the rack's foundational element. The drawer slides are incorporated into the base's internal geometry, eliminating the need for separate external storage containers or complex attachment mechanisms.
Solution Approach 2:
The base structure serves multiple functions: it provides structural support for the rack, contains the drawer mechanism for storing arms, and acts as the primary connection point for vertical supports. This multi-functionality reduces the need for additional components, offsetting the complexity introduced by the drawer mechanism.
3Volume of moving object
If the rack is designed for compact storage of arms in the base, then volume is reduced for portability, but ease of operation worsens due to difficulty of insertion and removal
Solution Approach 1:
The connection between arms and base employs a dynamic sliding mechanism rather than fixed rigid attachment. The arms feature tapered or cam-shaped ends that slide into corresponding receptacles on the base, allowing smooth insertion and removal through directional motion while maintaining secure holding when engaged.

AI summary
A rack that is designed to be connected to a wall for hanging sport boards that includes a casing, a drawer, several right and left arms with connectors that match corresponding connectors in the casing. The drawer can slide inside and outside the casing and to be contained inside the casing. The right and the left arms are designed to be connected to the casing facing outward and to the right and to the left sides. The arms are designed to receive the sport boards. The inner length of the drawer is equal to or greater than the length of the arms, and the inner width of the drawer is equal to or greater than the width of the arms. The drawer is designed to contain the arms when the rack is not in use.
