Solution Overview

Problem

Turbulence in aircraft and vehicles often leads to drink spillage, causing accidents and damage due to loose drinkware, which is difficult to manage and poses a safety risk for flight personnel.

Innovation Solution

A selectively engageable cupholder assembly with a rack and pinion mechanism, pivotable top and bottom members, and interlocking teeth design that securely holds beverages, providing stability and structural strength to prevent spills and accidents during turbulence.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a cupholder assembly is designed to be selectively engageable with interlocking teeth and rack and pinion mechanism, then the reliability of preventing drink spillage during turbulence is improved, but the device complexity increases

Engineering Contradiction:
Improveprevention of drink spillageVSAvoidmechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The cupholder assembly employs a selectively engageable mechanism that transitions between locked and unlocked states. The rack and pinion mechanism with interlocking teeth provides dynamic engagement capability, allowing the cupholder to be securely locked during turbulence or easily unlocked for access, thus improving reliability without requiring permanently complex structures.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The cupholder assembly is divided into distinct functional components: the rack component with interlocking teeth, the pinion mechanism for engagement, and the cupholder body. This segmentation allows each component to perform its specific function efficiently while simplifying the overall design and maintenance of the system.

Inventive Principle:
Principle #1Segmentation

2Strength

If the cupholder assembly uses interlocking teeth and rack and pinion mechanism for secure holding, then the strength and stability of the cupholder is improved, but the manufacturing complexity increases

Engineering Contradiction:
Improvestructural strengthVSAvoidmanufacturing complexity
Core Design Contradiction:
StrengthVSEase of manufacture

Solution Approach 1:

The rack and pinion mechanisms are integrated directly into the cupholder assembly structure rather than being separate components. The interlocking teeth are formed as part of the cupholder body and mounting structure, combining multiple functions into unified components that maintain structural strength while simplifying manufacturing processes.

Inventive Principle:
Principle #5Merging (Combining)

3Object-affected harmful factors

If the cupholder assembly is designed to prevent spillage during turbulence, then the safety for flight personnel is improved, but the ease of operation for accessing beverages is reduced

Engineering Contradiction:
Improvesafety hazard from spillsVSAvoidaccessibility of beverage
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The selectively engageable mechanism allows the cupholder to transition between a locked secure state during turbulence and an unlocked accessible state during normal operations. This dynamic capability ensures safety when needed while maintaining ease of operation during regular beverage access, resolving the contradiction between safety and accessibility.

Inventive Principle:
Principle #15Dynamics
