Movable Load Carrier Resolving Light Visibility and Tailgate Conflict
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Load carriers for motor vehicles often obstruct rear lights, making them invisible and susceptible to damage during vehicle maneuvering, as they project forward and cover the rear light arrangement.
Innovation Solution
A load carrier with a movable carrying arrangement that adjusts between driving and loading positions, allowing the load to remain on the support assembly, with a pivoting tailgate release mechanism and an upper loading level that protrudes to protect the rear lights while maintaining accessibility, and an optional expansion component for increased capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the load carrier projects forward to increase loading capacity, then the loading capacity is improved, but the rear light arrangement becomes obscured and susceptible to damage
Solution Approach 1:
The support arrangement is made movable relative to the support structure, allowing it to be adjusted between a driving position (retracted) and a loading position (extended). This dynamic adjustment enables the load carrier to project forward when loading is needed while retracting when not in use, thus maintaining rear light visibility and reducing damage risk during normal driving.
Solution Approach 2:
The invention introduces a temporal dimension to the spatial arrangement by allowing the support arrangement to change its position over time. The support arrangement can be in different positions (retracted or extended) depending on the operational phase, effectively using time as an additional dimension to resolve the conflict between loading capacity and rear light accessibility.
2Quantity of substance
If the load carrier is fixed in an extended position to maximize loading space, then the loading capacity is improved, but the tailgate pivoting range is obstructed
Solution Approach 1:
The support arrangement is designed to be movable rather than fixed, allowing it to be positioned in an extended state when loading is required and retracted when the tailgate needs to pivot. This dynamic positioning resolves the conflict between maximizing loading space and maintaining tailgate operability.
3Ease of operation
If the support arrangement is made movable to improve handling, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The load carrier system is divided into distinct segments: a fixed support structure and a movable support arrangement. This segmentation allows the support arrangement to be independently adjusted relative to the support structure, enabling improved handling through positional adjustment while keeping the overall structure relatively simple and modular.

AI summary
The carrier (10a) has a carrier structure (13) provided with a load to be carried and protruding in a working position of the carrier toward back of a rear end area of a motor vehicle. A lower load section (65) is arranged near a rear end of the vehicle and an upper load section (66) is removed from the rear end of the vehicle, where the lower and upper load sections exhibit same loading capacities. A rear light assembly (70) is arranged at the carrier structure. The rear light assembly is arranged within the upper load section and removed from a free end of the carrier.
