Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In commercial environments like airports, there is a disconnect in the experience for customers, workers, partners, and operators, with passengers lacking awareness of available resources and services during their journey.
Innovation Solution
An interactive kiosk equipped with a display, microphone, and processors that uses speech recognition to query back-end systems, providing users with product recommendations and facilitating purchases, while integrating with airport systems for real-time data and user-specific information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional static information displays are used in airports, then infrastructure complexity is minimized, but customer experience connectivity and resource awareness are insufficient
Solution Approach 1:
The kiosk is designed as a multi-functional platform that combines speech recognition, predictive modeling, personalized recommendations, real-time data integration, and e-commerce capabilities into a single device. This universal design allows the same hardware to serve multiple purposes: providing flight information, suggesting products based on passenger profiles, facilitating purchases, and offering directional guidance, thereby improving customer experience connectivity without requiring separate specialized systems for each function.
Solution Approach 2:
A virtual agent serves as an intermediary between the passenger and the complex underlying systems. The virtual agent translates passenger queries into actionable requests, processes information through predictive models, and presents simplified recommendations. This intermediary layer abstracts the complexity of the backend systems (reservation databases, retail inventory systems, airport navigation systems) from the user interface, allowing the kiosk to provide sophisticated services while maintaining simple user interaction.
2Adaptability or versatility
If predictive models are used to personalize recommendations, then service relevance is improved, but system transparency is reduced (black box problem)
Solution Approach 1:
The system incorporates feedback mechanisms that allow passengers to interact with and refine their personalized recommendations. Passengers can query about specific products or services, and the system adjusts its predictions based on these interactions. The feedback loop also includes monitoring passenger responses and modifying future recommendations, creating a dynamic adaptive system that improves service relevance while providing explainable adjustments based on observed user behavior.
Solution Approach 2:
The predictive modeling system is segmented into distinct, explainable components rather than operating as a monolithic black box. The system separates prediction functions into specific modules (e.g., product recommendation engine, timing optimization module, personalization filter) that can be individually explained to users. This segmentation allows the system to maintain high service relevance through sophisticated predictions while providing transparency by breaking down the complex modeling process into understandable segments.
3Productivity
If real-time data integration from multiple systems is implemented, then operational responsiveness is improved, but data processing complexity increases
Solution Approach 1:
The system performs preliminary data processing and pre-computation of predictive models in advance rather than processing all data in real-time. Flight schedules, product inventories, and passenger profiles are pre-loaded and indexed, allowing the kiosk to quickly query and combine this pre-processed information with real-time inputs. This preliminary action reduces the computational burden during actual passenger interactions, enabling operational responsiveness while managing data processing complexity through advance preparation.
Solution Approach 2:
Multiple data sources (airport operations systems, retail inventory systems, passenger reservation systems) are merged into a unified data architecture that presents a consolidated view to the kiosk. By combining these separate systems into a coordinated data layer, the kiosk can access integrated information without needing to independently query each source, thereby improving operational responsiveness through centralized data access while reducing the complexity of managing multiple separate data connections.
4Ease of operation
If multiple interaction modalities (speech, display, payment processing) are integrated, then user convenience is improved, but device complexity increases
Solution Approach 1:
The kiosk is designed to serve itself by automatically handling routine tasks without requiring manual intervention. The system autonomously captures passenger identification data, retrieves relevant information from databases, generates personalized recommendations, processes payments, and provides directional instructions. This self-service capability improves user convenience by eliminating the need for staff assistance while managing component complexity through automated workflows that reduce the need for complex manual control systems.

AI summary
An interactive kiosk includes a display, a microphone, and one or more processors that perform operations including receiving user input provided as a spoken query of a user, receiving user-specific data, querying, by a virtual agent, one or more back-end systems based on the user input, and the user-specific data to provide one or more responses, displaying one or more graphical representations of the one or more responses to the user on the display, the one or more graphical representations depicting at least one product for purchase, facilitating a purchase of the at least one product, and providing instructions to the passenger for physical retrieval of the at least one product within a location.
