Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing vehicle storage structures are inefficient in utilizing the inner space of the rear bumper as storage, often requiring inconvenient trunk lid operations and leaving the rear bumper unused, leading to insufficient storage functionality and potential moisture issues.

Innovation Solution

A storage apparatus with a storage case fixedly mounted to the inner space of the rear bumper, featuring a rotatable bumper door and tray cover that doubles as a step or bench, along with a support bracket and link members for enhanced usability and impact absorption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the trunk lid is opened and a storage case is drawn out for storage, then storage functionality is provided, but inconvenience is caused due to opening and closing operations of the trunk lid and the trunk room space may be polluted by moisture

Engineering Contradiction:

Improvestorage functionalityVSAvoidconvenience of access

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The storage case is extracted from the trunk room and relocated to the rear bumper area. The storage case is now positioned in the rear bumper instead of being stored in the trunk room, allowing users to access storage without opening the trunk lid, thus eliminating the inconvenience of trunk lid operations and preventing moisture pollution in the trunk room.

Inventive Principle:

Principle #2Taking out (Extraction)

2Ease of operation

If the rear bumper is used as a door for storage space under the vehicle, then storage access is enabled, but the inner space of the rear bumper corresponding to spare space is not used and storage function of the bumper is insufficient

Engineering Contradiction:

Improvestorage accessVSAvoidstorage function of bumper

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The rear bumper is designed to serve multiple functions: it acts as both a protective bumper and a storage structure. The storage case is integrated into the rear bumper, and the bumper door serves dual purposes as both a protective cover and a door to access the storage case. This multi-functionality maximizes the utilization of the rear bumper's inner space and enhances the overall storage function of the bumper.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Device complexity

If the inner space of the rear bumper is left unused as spare space, then the bumper structure remains simple, but storage functionality is insufficient and spare space is wasted

Engineering Contradiction:

Improvebumper structureVSAvoidstorage functionality

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The storage case is nested within the inner space of the rear bumper. The storage case fits into the spare space of the rear bumper, utilizing the available volume efficiently. The bumper door covers the storage case when closed, creating a nested configuration that maximizes space utilization without significantly increasing the external dimensions or complexity of the bumper structure.

Inventive Principle:

Principle #7Nested doll (Nesting)
