Shop Exit Detection for Timely Recommendation Delivery

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing techniques for providing information to users in physical shops do not ensure timely delivery of recommendations based on user actions, leading to potential missed opportunities for relevant information transmission.

Innovation Solution

An information processing device with a detecting unit to identify when a user exits a shop and a recommendation unit that transmits tailored information, considering purchase actions and substitute shops, using short-range wireless communication to eliminate the need for GPS activation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If recommendation information is transmitted based on user visit to a shop, then the user receives relevant information, but the timing may not be appropriate and the user may have already left the shop

Engineering Contradiction:

Improvetiming accuracy of recommendation deliveryVSAvoiddelay in recommendation delivery

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary detection of user exit from the shop before transmitting the recommendation information. By detecting that the user has exited the shop and then transmitting the recommendation information subsequently, the system ensures the information is delivered at an appropriate timing when the user is still potentially receptive, resolving the contradiction between timing accuracy and delivery delay.

Inventive Principle:

Principle #10Preliminary action

2Productivity

If recommendation information is transmitted to all users who visit a shop, then comprehensive coverage is achieved, but unnecessary recommendations are sent to users who completed their purpose

Engineering Contradiction:

Improveefficiency of recommendation deliveryVSAvoidrelevance of recommendation to user needs

Core Design Contradiction:

ProductivityVSLoss of information

Solution Approach 1:

The system applies local quality by differentiating recommendation delivery based on individual user behavior. Instead of uniform treatment, it specifically targets users who exited the shop without making a purchase, delivering recommendation information only to this particular group. This resolves the contradiction by ensuring recommendations are sent only where needed, improving efficiency while maintaining relevance.

Inventive Principle:

Principle #3Local quality

3Measurement precision

If GPS function is used to detect user location and shop exit, then accurate detection is achieved, but user convenience is reduced due to GPS activation requirement

Engineering Contradiction:

Improveaccuracy of user location detectionVSAvoiduser convenience in system usage

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The system replaces the mechanical GPS-based detection system with a wireless communication-based detection system. By using wireless communication signals to detect user presence and exit from the shop, the system achieves accurate location detection without requiring GPS activation, thus resolving the contradiction between measurement precision and ease of operation.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

An information processing device detects that a user has exited a shop, and transmits recommendation information based on information of the shop to a user who is detected to have exited the shop.
