Solution Overview

Problem

Existing luggage compartment floor devices in passenger cars lack flexibility in adapting to objects with different shapes and external dimensions, as the positioning of the fixing element is limited by the guide rails, making it difficult to securely transport items of varying sizes.

Innovation Solution

The introduction of additional guide rails that can move with the second luggage compartment floor element, allowing the fixing element to be displaced over a larger distance and adapted to different objects, combined with a pivotable and lockable design for easy handling and secure positioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the fixing element is constrained to move only along fixed guide rails, then the structure is simple and stable, but the adaptability to objects with different shapes and dimensions is poor

Engineering Contradiction:
Improveadaptability to objects with different shapes and dimensionsVSAvoidguide rail system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The guide rails are designed to be movable rather than fixed, allowing them to change position dynamically. The second guide rail can move relative to the first guide rail, enabling the fixing element to reach a broader range of positions to accommodate objects of various shapes and dimensions, thus resolving the contradiction between adaptability and structural simplicity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The guide rail system is divided into multiple segments - a first guide rail and a second guide rail that can move relative to each other. This segmentation allows independent adjustment of each rail segment to achieve optimal positioning for different cargo configurations, improving adaptability without requiring complete system redesign.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the second luggage compartment floor element is made movable to access storage space, then the versatility is improved, but the risk of unintended movement and reduced stability is increased

Engineering Contradiction:
Improveaccessibility to storage spaceVSAvoidstability of floor element positioning
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

A locking mechanism is provided to prevent unintended movement of the second luggage compartment floor element. The locking mechanism engages to secure the floor element in its desired position, cushioning against accidental displacement during cargo loading or vehicle operation, thus maintaining reliability while preserving mobility for accessing storage space.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The second luggage compartment floor element is designed with movable capability between a closed position and an open position, allowing dynamic adjustment for accessing the storage space underneath. This dynamic design enables the floor element to transition between stable closed state and accessible open state as needed.

Inventive Principle:
Principle #15Dynamics
