Foldable Double-Deck Frame Container for Vehicle Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing double-deck vehicle carrier frames are over-height and over-weight, leading to increased transportation costs and complexity due to the need for enhanced structural strength and compliance with size restrictions during international transport.
Innovation Solution
A foldable double-deck frame container design featuring a first and second corner post with a rotatable second corner post that can move between vertical and folded positions, allowing for adjustable height and width configurations, and an auxiliary spring structure for easy folding and securing, reducing the overall size and weight while maintaining strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the container body height is increased to accommodate double-deck vehicle transport, then the transport capacity is improved, but the transportation expenses and device complexity increase
Solution Approach 1:
The patent applies the dynamics principle by making the upper corner posts foldable, allowing them to change position between vertical (for double-deck transport) and folded (for reduced height) states. This dynamic structure enables the container to adapt its configuration based on transport requirements, resolving the contradiction between maintaining high transport capacity and reducing structural complexity and expenses.
2Strength
If the plate thickness is increased to satisfy strength requirements, then the structural strength is improved, but the container weight and cumbersome nature increase
Solution Approach 1:
The foldable upper corner posts allow the container to maintain full strength during double-deck transport when extended vertically, and reduce weight and dimension restrictions when folded. This dynamic configuration eliminates the need for permanently thickened plates, resolving the contradiction between strength requirements and weight reduction.
3Device complexity
If the container body height is reduced to meet road or railroad restrictions, then the transportation expenses are reduced, but the vehicle transport capacity is limited
Solution Approach 1:
The foldable upper corner posts enable the container to dynamically adjust its height: extended for double-deck vehicle transport to maximize capacity, and folded to meet road or railroad height restrictions. This resolves the contradiction between height compliance and transport capacity by allowing the container to optimize for either requirement based on transport conditions.
4Adaptability or versatility
If the second corner post is made foldable to reduce size, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The foldable second corner post with rotatable connection provides the container with adaptability to meet different size requirements. The rotational mechanism, while adding some complexity, enables the structure to transform between configurations, achieving high adaptability for different transport scenarios.
Solution Approach 2:
The auxiliary spring structure provides automatic assistance for folding the second corner post, reducing the manual effort required and simplifying the operation despite the mechanical complexity of the foldable mechanism.
