Solution Overview

Problem

Conventional pivotable luggage lockers mounted on side walls face challenges in accessing and closing due to the upward movement of luggage items, which can lead to damage and increased effort, and require complex production processes with thicker side walls and additional openings.

Innovation Solution

A pivotable luggage locker design with a holder attached to the outer side of the rear wall, distributing loads over a larger area, simplifying production, and incorporating an actuating mechanism with multiple holders to facilitate easy rotation and access, reducing torque and material costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the luggage locker is mounted on side walls with pivot axis above centroid, then the opening and closing effort is reduced, but the luggage item may contact the top element during closing causing damage or preventing closure

Engineering Contradiction:

Improveopening and closing effortVSAvoidluggage item damage risk

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

A cushioning element is introduced as an intermediary between the luggage item and the top element. This mediator absorbs the impact when the luggage item contacts the top element during closing, preventing damage while maintaining the beneficial low-effort operation achieved by positioning the pivot axis above the centroid.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Device complexity

If the holder is mounted on side faces at two points, then the structure is simpler, but the loads and torques on the vehicle structure are higher

Engineering Contradiction:

Improvemounting structure complexityVSAvoidtorque on vehicle structure

Core Design Contradiction:

Device complexityVSForce

Solution Approach 1:

The holder is repositioned from side face mounting to rear wall mounting, changing the spatial dimension of attachment. This dimensional change allows the holder to utilize the entire width of the rear wall for load distribution, effectively reducing torques on the vehicle structure while maintaining structural simplicity.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The holder is designed with multiple mounting points distributed across the rear wall width. This segmentation of the mounting interface allows loads to be distributed across multiple attachment locations, reducing the torque burden on any single point or small area of the vehicle structure.

Inventive Principle:

Principle #1Segmentation

3Force

If the holder is mounted on outer side of rear wall, then the loads are distributed over larger area reducing torque, but the production process becomes more complex

Engineering Contradiction:

Improvetorque distributionVSAvoidproduction process simplicity

Core Design Contradiction:

ForceVSEase of manufacture

Solution Approach 1:

The holder design serves multiple functions simultaneously: it provides the pivot axis for rotation, distributes loads across the rear wall width through its mounting structure, and integrates with the luggage locker body. This multi-functionality consolidates what could be separate complex components into a single integrated element, simplifying production despite the advanced mounting requirements.

Inventive Principle:

Principle #6Universality (Multi-functionality)

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

The design enhances accessibility and reduces the effort required for opening and closing, while simplifying production and reducing material costs by distributing loads and torque more efficiently, providing a larger stowage space without increasing the vehicle's interior complexity.
