Ceiling Hoist Lateral Strap Alignment for Kayak Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hoists and lifts are not well-suited for supporting and lifting large sporting goods like kayaks, surfboards, and canoes, as they are often unstable and require complex components, making it difficult to securely lift and store these items.
Innovation Solution
A hoist assembly comprising a rope, mounts, lift pulleys, support straps, and a lateral strap that maintains the pulleys' alignment, allowing for stable lifting and securing of items like kayaks, surfboards, and canoes by adjusting the strap length and using a rope brake for secure storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing hoists and lifts are used for supporting large sporting goods, then lifting capability is provided, but stability deteriorates causing the device to be unstable and prone to moving during lifting
Solution Approach 1:
The hoist assembly is divided into distinct functional components: ceiling mounts for secure attachment, lift pulleys for mechanical advantage, support straps for item securing, and a lateral strap for alignment maintenance. This segmentation allows each component to be optimized for its specific function, improving overall stability while simplifying operation.
Solution Approach 2:
The lateral strap is pre-configured to connect between the first and second lift pulleys before lifting begins. This preliminary action establishes proper alignment and prevents the pulleys from shifting during the lifting operation, thereby maintaining stability throughout the process.
2Ease of operation
If existing hoists and lifts are used for lifting large sporting goods, then lifting function is achieved, but device complexity increases requiring various components to lift and secure an item
Solution Approach 1:
The invention combines multiple functions into an integrated assembly: the ceiling mounts provide structural support, the pulleys provide mechanical advantage, the support straps secure the item, and the lateral strap maintains alignment. This merging of functions into a coordinated system achieves secure item storage while maintaining operational simplicity.
Solution Approach 2:
The hoist assembly is designed with universal applicability to various large sporting goods such as kayaks, canoes, and surfboards. The adjustable support straps and configurable lateral strap allow the same assembly to securely lift and store different types of items, reducing the need for multiple specialized devices.
3Stability of the object's composition
If existing hoists and lifts are used for supporting items, then lifting capability is provided, but alignment stability deteriorates making it difficult to maintain position during lifting
Solution Approach 1:
The lateral strap serves as an intermediary element connecting the first and second lift pulleys. It mediates the relationship between the pulleys by maintaining their relative positions and preventing lateral displacement during lifting, thereby ensuring alignment stability without requiring complex mechanical guides or rigid structures.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The hoist assembly provides a simple and stable solution for lifting and securing large sporting goods, preventing strap slippage and maintaining alignment during lifting, reducing effort and ensuring secure storage near a ceiling.
Implementation Method 1
a first lift pulley located substantially beneath the first mount, the first lift pulley movably associated with the first mount with the rope; a second lift pulley located substantially beneath the second mount, the second lift pulley moveably associated with the second mount with the rope
Implementation Method 2
a rope brake located proximate to one of the first mount and the second mount
