Detachable Loading Basket with Curved Guide for Vehicle Luggage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cars with raised loading sills in luggage compartments make loading and unloading heavy objects difficult, particularly in limousines where the rear area is hard to access, causing strain on the user's spine.
Innovation Solution
A detachable loading device with a guided loading basket that can be adjusted in height and depth, featuring lateral guides and a roller mechanism for easy access and secure positioning, which can be adapted to different vehicle types and used with or without a chassis for additional support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a raised loading sill is provided in the luggage compartment, then the structural integrity and design of the vehicle is maintained, but loading and unloading heavy objects becomes difficult and causes strain on the user's spine
Solution Approach 1:
A loading basket is introduced as an intermediary device between the user and the heavy objects in the luggage compartment. The basket is pulled out along a curved guide path that raises it to the level of the loading sill, allowing users to load and unload objects at an ergonomic height without bending over the raised loading sill, thereby eliminating spine strain while maintaining vehicle structural integrity
Solution Approach 2:
The loading basket is moved from a static position within the luggage compartment to a dynamic position outside the vehicle through a curved guide path. This dimensional transition from inside to outside the vehicle structure allows the basket to be positioned at an ergonomically favorable height, resolving the contradiction between maintaining the raised loading sill structure and enabling easy loading/unloading
2Ease of operation
If the loading basket is pulled out of the luggage compartment, then access to heavy objects is improved, but the basket must be raised to loading sill level which requires vertical space
Solution Approach 1:
A curved guide path is used instead of a straight vertical or horizontal path to move the loading basket. The curved trajectory allows the basket to be raised to loading sill level while being pulled out horizontally, optimizing the use of available space and reducing the vertical space requirement compared to a purely vertical lifting mechanism
3Adaptability or versatility
If a detachable loading device is used, then the device can be removed easily and completely without leaving residue, but the device complexity increases with adjustment mechanisms
Solution Approach 1:
The loading device is segmented into separate components: a loading frame with adjustment mechanisms and a loading basket. This segmentation allows the entire device to be easily removed and reinstalled, while also enabling the loading basket to be used independently as a shopping cart, thereby increasing versatility without requiring overly complex integrated mechanisms
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates simple and ergonomic loading and unloading of heavy objects by raising the basket to the loading sill level, reducing strain and allowing easy conversion to a shopping cart for convenience.
Implementation Method 1
The roller is provided at the upper front corner of each side wall (near the loading sill when installed) and protrudes with its circular surface in the direction of the opposite side wall, so that when the loading basket is pulled out, it rolls on its slanted front and then on its bottom.

AI summary
The loader has a skid detachably fastened in a luggage compartment. The skid is provided for receiving a loading basket (02) which is arranged in the skid in lateral guides. The skid has two side walls and the guides are formed in each side wall by a groove or by a roller. A pin fastened at the loading basket is guided in the groove and the roller is provided at the front upper corner of the side walls.
