Pivoting Load Carrier Platform for Rear Door Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing carrier devices for vehicles obstruct rear access when loaded, requiring removal of the load to open rear doors, which is inconvenient and risks damage to the load during handling.
Innovation Solution
A carrier device with a pivoting supporting platform that can be oriented parallel or at an angle to the guide means, allowing it to retract and avoid obstructing the rear of the vehicle, eliminating the need to remove the load to access the rear doors, and featuring a guide element that moves with the platform to maintain load security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the carrier device is attached to the rear end of the vehicle, then the load can be transported on the vehicle, but the rear door is blocked and cannot be accessed
Solution Approach 1:
The supporting platform is made dynamically movable relative to the guide means through the pivot means, allowing it to be pivoted between a first position (parallel to guide means, blocking rear door) and a second position (angled to guide means, clear of rear door). This dynamic repositioning resolves the contradiction by enabling the platform to adapt its position based on whether load transport or rear door access is the current priority.
Solution Approach 2:
The pivot means introduces a rotational degree of freedom, moving the supporting platform from a purely linear extension along the guide means into a different spatial dimension (angular orientation). By pivoting the platform sideways relative to the guide means, it clears the rear door path while maintaining its attachment to the vehicle, thus resolving the spatial conflict between load transport and door access.
2Ease of operation
If the load is removed from the carrier device to open the rear door, then the rear door can be accessed, but the operation becomes inconvenient and the load is at risk of damage
Solution Approach 1:
The pivot means enables the supporting platform to be dynamically repositioned to clear the rear door without removing the load. The load remains securely mounted on the platform throughout the pivoting operation, eliminating the need for load removal and associated handling risks while maintaining rear door accessibility.
Solution Approach 2:
The pivot means acts as an intermediary mechanism between the carrier device and the rear door space. By enabling the platform to pivot sideways, it creates sufficient clearance for door access while keeping the load in its secured position on the platform, thus mediating between the conflicting requirements of door access and load security.
3Reliability
If the supporting platform is oriented parallel to the guide means, then the load is securely positioned, but the device occupies excessive space at the rear of the vehicle
Solution Approach 1:
The pivot means enables the supporting platform to dynamically change its orientation from parallel to the guide means (first position, maximum load security) to angled relative to the guide means (second position, reduced space occupation). This dynamic repositioning allows the system to optimize between load security and space efficiency based on operational requirements.
Solution Approach 2:
By introducing rotational movement through the pivot means, the platform can move from a linear extension configuration into an angular configuration relative to the guide means. This dimensional change reduces the platform's projection from the rear of the vehicle while maintaining its load-carrying capability, thus resolving the space occupation issue.
