Solution Overview

Problem

Conventional vehicle roofs do not open efficiently, requiring fabric or complex parts that consume excessive cargo space and height clearance.

Innovation Solution

A convertible roof control mechanism with a curved arm, pistons, tracks, and a pushing mechanism, allowing the roof panels to slide into the trunk, utilizing motorized gears and actuators for secure and space-efficient opening and closing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional convertible roof mechanisms are used, then the roof can open and close, but the mechanism requires significant height clearance and consumes excessive cargo space

Engineering Contradiction:
Improveroof opening and closing capabilityVSAvoidcargo space
Core Design Contradiction:
Ease of operationVSVolume of stationary object

Solution Approach 1:

The roof panels are designed to nest within each other during the opening sequence. The front panel folds down and nests within the rear panel, which itself nests within the cargo area, creating a compact stacked configuration that minimizes space requirements

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The mechanism transitions from traditional vertical folding (requiring height clearance) to a horizontal sliding and nesting motion. The panels move laterally into the cargo area and stack vertically within the available depth, effectively changing the dimension of movement from height-based to depth-based

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If conventional convertible roof mechanisms are used, then the roof can open and close, but the mechanism requires many complicated parts

Engineering Contradiction:
Improveroof opening and closing capabilityVSAvoidnumber of parts
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

Multiple functions are merged into single components. The sliding mechanism simultaneously performs the functions of support, guidance, and positioning. The nesting action combines folding, stacking, and securing operations into a single continuous motion sequence

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The sliding mechanism serves multiple purposes: it supports the roof panels during movement, guides their trajectory, positions them in the final nested configuration, and secures them in place. This multi-functional design eliminates the need for separate components for each function

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

3Shape

If fabric is used for the convertible roof, then the roof can fold compactly, but the mechanism still requires significant height clearance

Engineering Contradiction:
Improvecompact folding capabilityVSAvoidheight clearance
Core Design Contradiction:
ShapeVSLength of stationary object

Solution Approach 1:

The mechanism changes from vertical folding (requiring height clearance) to horizontal sliding followed by vertical nesting within the cargo depth. The panels slide horizontally into the cargo area first, then nest vertically within the available depth space, eliminating the need for external height clearance

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

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

Enables the vehicle roof to open and close compactly, optimizing cargo space and height clearance, while securely supporting the roof's weight and ensuring smooth operation.

Implementation Method 1

The front of the curved up arm lifted, the front of the curved arm has one or more motorized gears which after the front of the curved up is pivoted upwards spin and the teeth of the gears (or the grippiness of the grippy wheels) slide a track inside the front panel backwards

Methodology Applied
Scientific EffectMechanical advantage through gears: Gear

Implementation Method 2

pistons which slide out from the front of the front panel and lock into the rear of the windshield frame so as to secure the front panel of the roof to the vehicle and also to support the weight of the front panel and roof

Methodology Applied
Scientific EffectHydraulic or pneumatic actuation: Hydraulic Press

Implementation Method 3

a curved arm which connects the front and rear panel, and where the arm pivots inside the front of the rear panel such that the front of the curved up arm lifted

Methodology Applied
Scientific EffectLeverage and pivot mechanism: Lever
