Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing installations for secure access to the upper part of vehicles are expensive, space-consuming, and require multiple stairways, which are inconvenient and inefficient.
Innovation Solution
The installation features a fixed frame with a vertically movable support structure, allowing for horizontal movement of longitudinal platforms without the need to descend to the ground floor, thereby reducing space requirements and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional installations use multiple uprights to handle loads, then structural strength is improved, but space requirements increase and cost increases
Solution Approach 1:
The patent combines multiple support functions into a single integrated movable support structure. Instead of using multiple separate uprights distributed across the space, the invention uses one consolidated movable support structure that performs all support functions, thereby reducing space requirements while maintaining structural strength.
Solution Approach 2:
The movable support structure is designed to perform multiple functions: supporting longitudinal platforms, enabling vertical movement, allowing horizontal movement, and providing lateral support. This multi-functional design eliminates the need for multiple specialized uprights, reducing both space and cost while maintaining structural integrity.
2Ease of operation
If conventional installations use multiple stairways for access, then accessibility to both sides is improved, but device complexity and cost increase
Solution Approach 1:
The patent merges the functions of multiple stairways into a single stairway arrangement. The movable support structure enables staff to access both longitudinal platforms through one stairway by horizontally moving the platform to the required position, thereby providing full accessibility while halving the number of stairways needed.
Solution Approach 2:
The system uses dynamic horizontal movement of the longitudinal platforms to adapt to different access requirements. Instead of having static multiple stairways for different positions, the platform can be moved horizontally to bring the single stairway to the required access point, maintaining ease of operation while reducing complexity.
3Device complexity
If conventional installations require staff to climb down to floor level to move sides, then structural simplicity is maintained, but productivity and efficiency deteriorate
Solution Approach 1:
The patent introduces dynamic horizontal movement capability to the support structure, allowing platforms to be repositioned laterally without returning to ground level. This dynamic feature enables staff to move between sides efficiently while maintaining a relatively simple structural design, as the movement is achieved through integrated actuators rather than complex mechanical systems.
Solution Approach 2:
The movable support structure acts as an intermediary between the fixed frame and the longitudinal platforms. It mediates the movement requirements by providing both vertical and horizontal movement capabilities, allowing staff to transition between sides efficiently without requiring complex separate mechanisms for each movement type.
