Pivoting Wheelbarrow Gripping Assembly for Compact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wheelbarrows are bulky due to their extendable stretchers, making storage and transport inconvenient for users and manufacturers, and existing solutions like telescopic or folding systems can be prone to malfunctions or require complex operations.
Innovation Solution
A wheelbarrow with a pivoting gripping assembly that can be easily folded and unfolded in a minimal number of operations without tools, using a locking mechanism with a retaining portion and a torsion spring to secure the assembly in place, allowing for a compact configuration without affecting handling during load transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the handles are made extendable to improve handling capability, then the wheelbarrow can accommodate larger loads, but the wheelbarrow becomes bulkier and harder to store
Solution Approach 1:
The gripping assembly is designed to be dynamically reconfigurable between extended and folded positions. The pivoting mechanism allows the handles to transition from a rigid extended configuration during load transport to a compact folded configuration during storage, optimizing the wheelbarrow's volume适应性.
Solution Approach 2:
The gripping assembly is segmented into multiple parts that can pivot relative to each other. The first and second gripping portions can be positioned at different angles and distances from the chassis, allowing the assembly to be extended for handling or folded for storage without affecting the overall wheelbarrow structure.
2Volume of moving object
If a telescopic system is used to reduce wheelbarrow bulk, then storage becomes easier, but the system becomes prone to jamming and mechanical failures
Solution Approach 1:
The pivoting gripping assembly uses a dynamic pivot joint mechanism rather than a fixed telescopic slide. This allows the handles to be easily folded and unfolded through simple pivoting motion, avoiding the jamming issues of telescopic systems while maintaining compact storage capability.
Solution Approach 2:
The pivoting mechanism is designed to be self-operating through simple user action. The gripping assembly pivots naturally between folded and extended positions without requiring complex locking mechanisms or risking jamming, making the system more reliable and easier to use.
3Volume of moving object
If folding handles are used to reduce bulk, then storage becomes more compact, but the folding operation becomes cumbersome and complex
Solution Approach 1:
The pivoting gripping assembly is designed for dynamic reconfiguration with minimal effort. The pivot joints allow the handles to be folded and unfolded through simple pivoting motions, eliminating the need for complex folding operations while achieving compact storage.
Solution Approach 2:
The gripping assembly is divided into segments that pivot independently, allowing each portion to be positioned optimally. This segmentation enables simple folding operations where each segment can be pivoted to its storage position without requiring complex coordinated movements.
4Volume of moving object
If the gripping assembly is made foldable to reduce bulk, then storage becomes easier, but the assembly may affect handling during load transport
Solution Approach 1:
The pivoting gripping assembly allows the handles to be dynamically positioned between extended and folded configurations. During load transport, the assembly can be extended for optimal handling, and during storage, it folds to minimize bulk, ensuring that handling during transport is never compromised.
Solution Approach 2:
The gripping assembly is segmented into multiple pivotable portions that can be independently positioned. This allows the assembly to be extended during transport for proper handling and folded during storage, with each segment contributing to the overall functionality without compromising either phase.
