Solution Overview

Problem

Existing solutions for vehicle trunk loading floors lack variability, as height-adjustable solutions in larger vehicles do not allow division of space, while solutions in smaller vehicles do not allow height adjustment, and fixing the loading floor in functional positions is problematic.

Innovation Solution

A multifunctional adjustable loading floor system where the middle and rear floor panels can be adjusted from a lower to an upper position, secured by a locking device involving a housing, locking lever, and hinged support, allowing for stable trunk division and secure positioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a height-adjustable floor panel is used, then the loading floor can be raised to form a flat surface with the sill, but the floor panel becomes unstable and can collapse accidentally

Engineering Contradiction:
Improveheight adjustment capabilityVSAvoidfloor panel stability
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The locking device is designed to automatically engage when the floor panels are raised to the desired position. The locking lever and locking pin mechanism预先 prepares the locking action, so that once the panels are positioned, they are immediately secured against accidental collapse without requiring additional manual intervention.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The locking mechanism is designed to automatically lock the floor panels in the raised position through the interaction of the locking lever, locking pin, and hinged support. The system self-secures the panels without requiring external assistance, and the spring element ensures the locking lever returns to the locked position after actuation.

Inventive Principle:
Principle #25Self-service

2Stability of the object's composition

If a locking device is added to secure the floor panel in the upper position, then the floor panel stability is improved, but the device complexity increases

Engineering Contradiction:
Improvefloor panel stabilityVSAvoidlocking device complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The locking device uses a simple intermediary mechanism consisting of a locking lever, locking pin, and hinged support. These components mediate between the floor panels and the vehicle structure, providing stable locking through geometric constraints and mechanical interference rather than complex active control systems.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The invention relates to a multifunctional adjustable loading floor (1) for a luggage compartment of a motor vehicle, and which is arranged between vehicle lateral walls (3), backrests (2), and a rear cross-member (4). Said multifunctional adjustable loading floor (1) consists of a front, middle and rear floor panel (18, 19, 20) which are connected such that they can pivot with respect to one another, a fixing device (26) being arranged on the underside of the front and the rear floor panels (18, 19), lying against the lateral walls (3). This fixing device is formed from a housing (27) arranged on the underside of the front floor panel (18), an arresting actuator finger (29) arranged on the underside of the middle floor panel (19), and a folding support (6) arranged on the lateral wall (3). The individual parts of the fixing device (26) mutually interact such that the multifunctional adjustable loading floor (1) can be adjusted from a lower position in which it lies upon the substrate of the luggage compartment, into an upper position in which it lies flush with a lock cover (9) on the rear cross-member (4). In both of these positions, the middle and rear floor panels (19, 20) can be adjusted into a stable position that divides the luggage compartment.
