Tool-Free Barrier Accessory Device for Watercraft
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing watercraft accessory devices require tools for securement to barrier structures and often limit the size and type of accessories that can be connected, making them inconvenient for recreational use.
Innovation Solution
A barrier accessory device featuring a connection base with adjustable rail connectors, including a slot-engaging member and a locking assembly, allowing for tool-free and versatile attachment of accessories to both upper and lower rails of the watercraft's barrier structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional connection devices are used to secure accessories to the barrier structure, then the accessories can be connected to the barrier structure, but tools are required for securement which increases operation time and complexity
Solution Approach 1:
The locking assembly is designed to be self-latching once engaged. The locking member automatically locks into place when the accessory connection base is pressed against the barrier structure, eliminating the need for manual tool operation or multiple securing steps. This self-service mechanism directly resolves the contradiction by enabling tool-free securement while minimizing time loss.
Solution Approach 2:
The connection device is divided into distinct functional segments: the accessory connection base for holding accessories, the rail connector for engagement with the barrier structure, and the locking assembly for securing. This segmentation allows each component to perform its specific function efficiently, with the locking assembly providing rapid engagement without requiring tools, thus improving ease of operation and reducing time loss.
2Adaptability or versatility
If existing connection devices are used, then accessories can be connected to the barrier structure, but only small and/or light accessories can be connected which limits versatility
Solution Approach 1:
The accessory connection base is designed with a universal mounting interface that can accommodate various accessory types and weights through the same connection mechanism. The locking assembly provides sufficient connection strength for different accessory categories (from small lightweight items to larger heavier items) without requiring different connection devices, thereby achieving versatility while maintaining adequate strength across applications.
Solution Approach 2:
The locking member is designed to be movable between locked and unlocked positions, allowing the connection device to dynamically adjust to different accessory weights and sizes. The spring-loaded or movable locking mechanism can engage with varying force levels appropriate for different accessory types, enabling the same connection device to handle both small lightweight and larger heavier accessories securely.
3Ease of operation
If traditional connection methods are used, then accessories can be secured to the barrier structure, but the connection process requires tools which increases device complexity
Solution Approach 1:
The locking assembly functions as a self-service mechanism that automatically engages and locks without requiring external tools. The spring-loaded or movable locking member automatically latches when the accessory connection base is pressed against the barrier structure, providing tool-free operation. This self-service approach resolves the contradiction by eliminating the need for tools while keeping the overall device complexity manageable through integrated design.
Solution Approach 2:
The locking assembly merges multiple functions into a single integrated component: engagement with the barrier structure, locking action, and accessory connection all occur through one unified mechanism. By combining these functions into a single integrated assembly rather than separate components requiring individual tool operation, the design achieves tool-free operation while minimizing the increase in device complexity through consolidation.
