Solution Overview

Problem

Existing vehicle frunks lack expandable or unfoldable modules that provide additional storage and functional surfaces for users, limiting their utility and convenience.

Innovation Solution

A module for a vehicle frunk that can be expanded or unfolded outside the vehicle, incorporating features like a front hood, grill, and storage compartments, which can be manually or automatically controlled, and supported by extendable legs to create a stable surface for various uses.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a traditional fixed frunk design is used, then the vehicle structure is simple and easy to manufacture, but the storage capacity and functional versatility are limited

Engineering Contradiction:
Improvefunctional versatilityVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The frunk module is designed with expandable and collapsible components that can dynamically change configuration between a compact stored state and an expanded functional state. The module includes extendable sides, adjustable shelves, and deployable surfaces that transform from a minimal profile to a spacious functional area, resolving the contradiction between versatility and structural simplicity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The frunk system is divided into modular components including a base module, extendable side modules, adjustable shelving units, and detachable functional elements. This segmentation allows the system to achieve high versatility through combination of parts while maintaining manufacturing simplicity through standardized modular components that can be produced independently and assembled as needed.

Inventive Principle:
Principle #1Segmentation

2Volume of moving object

If an expandable module is added to the frunk, then storage capacity and functional surfaces are increased, but the device complexity and manufacturing difficulty increase

Engineering Contradiction:
Improvestorage capacityVSAvoidmanufacturing ease
Core Design Contradiction:
Volume of moving objectVSEase of manufacture

Solution Approach 1:

The expandable frunk module employs a nested configuration where smaller functional components are stored within the main frunk cavity when not in use. The side extenders, shelving units, and functional surfaces are designed to fold or nest within the basic frunk structure, maximizing storage capacity when deployed while minimizing the occupied volume and simplifying manufacturing by eliminating the need for separate permanent structures.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Ease of operation

If the frunk module is made expandable and unfoldable, then user lifestyle options and convenience are enhanced, but the mechanism complexity and control systems increase

Engineering Contradiction:
Improveuser convenienceVSAvoidcontrol system complexity
Core Design Contradiction:
Ease of operationVSExtent of automation

Solution Approach 1:

The frunk module incorporates self-service mechanisms where the expansion and collapse actions are initiated and executed by the user through simple manual operations. The design includes user-activated latches, manual extension handles, and gravity-assisted folding mechanisms that eliminate the need for complex automated control systems, motors, or electronic sensors, thereby enhancing user convenience while minimizing control system complexity.

Inventive Principle:
Principle #25Self-service
