Portable Crane Modular Boom for Window Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cranes lack a specific design for safely and efficiently installing and removing windows, particularly in confined spaces, and often require multiple people to operate, risking injury and potential window damage.
Innovation Solution
A portable crane with a wheeled base, boom support assembly, and adjustable boom system that allows for easy setup and operation by one person, featuring winches, pulleys, and a support bar assembly to securely lift and maneuver windows without causing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a portable crane is designed for installing and removing windows, then the safety and efficiency of window installation is improved, but the device complexity increases
Solution Approach 1:
The crane is divided into separate modular components including a base assembly, boom assembly, and support assembly that can be independently assembled and disassembled. This segmentation allows the complex structure to be managed through standardized connections while maintaining safety through proper modular assembly.
Solution Approach 2:
The crane design incorporates universal features that can accommodate different window sizes and installation scenarios through adjustable boom lengths and configurable support positions, reducing the need for multiple specialized devices while maintaining safety across various applications.
2Ease of operation
If a portable crane is designed for confined spaces, then the ease of operation is improved, but the stability of the crane decreases
Solution Approach 1:
The base assembly includes adjustable positioning mechanisms that allow the crane to adapt its configuration dynamically to different spatial constraints while maintaining stability through adjustable leg positions and configurable support structures that can be modified based on the specific installation environment.
Solution Approach 2:
The crane employs adjustable parameters including variable boom lengths, configurable support positions, and adjustable base configurations that can be modified to optimize both stability and ease of operation in confined spaces by changing physical dimensions and geometric relationships.
3Ease of operation
If a portable crane is designed for one-person operation, then the ease of operation is improved, but the productivity decreases
Solution Approach 1:
The crane incorporates self-positioning and self-adjusting mechanisms that allow a single operator to independently set up, position, and configure the device without requiring assistance from additional personnel, thereby maintaining productivity while enabling one-person operation through automated or self-contained functional elements.
