Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adjustable platform dollies are inefficient on rough terrain, lack versatility in handling different load sizes, and often fail to maintain direction, leading to load instability and difficulty in loading and transporting items.
Innovation Solution
An adjustable all-terrain dolly system with a chassis assembly featuring telescopically extendable cross members, inline wheels, and adjustable-locking mechanisms, allowing for secure transport of loads over varied surfaces and enabling easy adjustment for different load sizes and orientations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional platform dollies are used on rough terrain, then they can transport loads, but they cannot handle rough terrain efficiently
Solution Approach 1:
The dolly incorporates adjustable cross members that can be repositioned along the side rails to adapt to different load sizes and orientations. This dynamic adjustability allows the dolly to maintain stability and reliability across varying terrain conditions and load configurations, resolving the contradiction between reliable transport and terrain adaptability
Solution Approach 2:
The dolly design allows changing of geometric parameters including cross member position, side rail spacing, and platform configuration. These parameter changes enable the dolly to optimize its performance for specific terrain types and load requirements, simultaneously improving reliability and adaptability
2Adaptability or versatility
If fixed-size platform dollies are used, then they have simple structure, but they do not expand to handle different sized loads
Solution Approach 1:
The dolly is divided into modular components including side rails, cross members, and rolling assemblies that can be independently adjusted and reconfigured. This segmentation allows the structure to adapt to different load sizes while maintaining relatively simple individual components, resolving the contradiction between adaptability and structural complexity
Solution Approach 2:
The cross members are designed to be movable along the side rails rather than fixed, allowing the platform dimensions to dynamically adjust to different load requirements. This dynamic feature provides load size adaptability without requiring multiple complete dolly structures, managing the complexity effectively
3Reliability
If non-adjustable platform dollies are used, then they have simpler mechanism, but they are difficult to load and loads may fall off
Solution Approach 1:
The adjustable cross members can be repositioned to securely accommodate loads of various sizes and shapes, improving load stability and preventing loads from falling off. The locking mechanism ensures the adjusted position is maintained during transport, achieving reliability without excessive mechanism complexity
Solution Approach 2:
The dolly allows adjustment of platform parameters such as width and length by repositioning cross members along the side rails. This parameter adaptability enables secure loading of diverse items while maintaining a relatively simple overall mechanism, resolving the contradiction between load stability and mechanism complexity
4Adaptability or versatility
If adjustable cross members are added to the dolly, then different load sizes can be handled, but the device becomes more complex
Solution Approach 1:
The frame is segmented into side rails and independent cross members that can be adjusted separately. This segmentation provides load configuration flexibility while keeping each component relatively simple, resolving the contradiction between adaptability and structural complexity
Solution Approach 2:
The cross members serve multiple functions: they define platform boundaries, support loads, and can be adjusted to accommodate different load configurations. This multi-functionality provides versatility without proportionally increasing structural complexity, as the same components perform multiple roles
