Solution Overview

Problem

There is a challenge in stowing portable tables in vehicles without causing damage to the vehicle or the table during outdoor activities like camping or tailgating.

Innovation Solution

A multi-purpose interior cabin lid for vehicles that can be converted into a rear wall cover, a detachable storage bin lid, a tailgate extension, and a freestanding table, utilizing a base member with coupling members and leg members for versatile functionality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a portable table is carried in a vehicle for outdoor activities, then convenience and usability are improved, but risk of damage to the vehicle or table increases

Engineering Contradiction:
Improveconvenience of portable tableVSAvoiddamage risk to vehicle or table
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent combines the portable table with the vehicle's existing cabin lid structure, creating an integrated solution where the table is built into the vehicle rather than being a separate portable item. The base member integrates with the cabin lid, and the leg members fold into the cabin cavity when not in use, eliminating the need to carry separate tables and reducing damage risk.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The leg members are designed to nest within the cabin cavity when retracted, similar to a nested doll structure. This allows the table to be compact when not in use and eliminates the need for separate storage space, reducing the risk of damage during transport.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Adaptability or versatility

If a multi-purpose cabin lid is designed with additional functionalities, then versatility and adaptability are improved, but device complexity increases

Engineering Contradiction:
Improvemulti-purpose functionalityVSAvoidstructural complexity of cabin lid
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The cabin lid is designed as a universal structure that can serve multiple functions: as a closure for the cargo area, as a table surface with deployed leg members, and as an integrated storage solution. The base member and coupling members are designed to accommodate different configurations without requiring separate components for each function.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The leg members are designed with dynamic movement capabilities, allowing them to transition between retracted and deployed positions. This dynamic design enables the structure to adapt its configuration based on usage requirements while maintaining a relatively simple base structure that doesn't require complex mechanisms for each function.

Inventive Principle:
Principle #15Dynamics

AI summary

A vehicle and multi-purpose interior cabin lid for a vehicle that has use as a rear wall cover for one or more storage compartments in the interior cabin, a tailgate extension connectable to a vehicle tailgate, and a portable, freestanding table. The multi-purpose interior cabin lid member includes a base member, one or more coupling members, and one or more leg members coupled to the base member. The one or more coupling members are operable to selectively couple the base member in the interior cabin as a cover for the one or more storage compartments, and selectively couple the base member to a vehicle tailgate to serve as a tailgate extension. The one or more leg members are selectively coupled to the base member for movement between a retracted operating state when the base member is in an undetached operating state, and a deployed state to vertically support the base member on a support surface.
