Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protective devices for motor vehicle loading spaces lack advanced functionality and comfort, as they often require manual operation and occupy valuable space when not in use, and may not securely manage the pull-out profile during obstacles.
Innovation Solution
A protective device with a cassette housing that can be automatically lowered into the loading space floor, featuring a drive system with synchronized drivers and a locking mechanism, allowing for fully automatic operation and secure vertical displacement of the receiving structure, along with a catch link and locking device to manage the pull-out profile.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the receiving structure is lowered into the loading space floor when not required, then the space available in the loading space is optimized, but the complexity of the displacement mechanism increases
Solution Approach 1:
The receiving structure is designed to be nestable within the loading space floor when in the lowered position, allowing the housing to be stored within a recess or cavity in the floor structure, thereby optimizing space utilization while managing structural complexity through integrated design
Solution Approach 2:
The receiving structure is made dynamically positionable between a lowered rest position and an elevated functional position, allowing it to adapt its height based on operational requirements, thus optimizing space availability while maintaining a manageable displacement mechanism through controlled movement
2Ease of operation
If fully automatic operation is provided for shifting catches and height shifting, then functionality and comfort are improved, but the complexity of the drive system increases
Solution Approach 1:
Multiple drive functions (shifting catches laterally and height shifting of the receiving structure) are merged into a single integrated drive mechanism that performs both operations through coordinated movement, thereby achieving full automatic operation while minimizing drive system complexity through functional consolidation
Solution Approach 2:
The drive system is designed with multi-functionality, where a single drive mechanism performs multiple operations (lateral catching and vertical displacement) through different phases of its operation, reducing the need for separate drive components and simplifying the overall system while providing fully automatic functionality
3Reliability
If the pull-out profile is securely managed during obstacles, then reliability is improved, but the complexity of the coupling device increases
Solution Approach 1:
The coupling device incorporates a catching link that is designed to engage with the pull-out profile in advance, providing a pre-positioned safety mechanism that secures the profile during obstacle events, thereby improving reliability while maintaining relatively simple device complexity through proactive design
