Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current map services face challenges in effectively displaying target content based on user location, leading to data noise and decreased user interest due to small icons and irrelevant search results, especially when a large number of search results are present.

Innovation Solution

A map service method and system that uses a spot finder with a defined radius based on the user's location, providing target content through a marker and a list of nearby locations, with features like hashing algorithms for searching and user-defined categories, and a scrolling function for managing multiple results.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If search results are displayed as icons on a map based on keyword search, then information can be provided to users, but data appears as noise and user interest decreases

Engineering Contradiction:

Improvesearch result visibilityVSAvoiddata noise

Core Design Contradiction:

Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The patent segments search results by geographic location, organizing them into location-based groups rather than displaying all results uniformly. This segmentation allows users to focus on relevant local results while filtering out distant irrelevant data, thereby reducing noise while maintaining information visibility.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by prioritizing display of search results based on their proximity to the user's current location. Results closer to the user are displayed with higher prominence, while distant results are either dimmed or excluded. This creates a quality gradient where locally relevant information stands out and distant noise is suppressed.

Inventive Principle:

Principle #3Local quality

2Quantity of substance

If a large amount of search results is acquired, then comprehensive information is available, but dead data increases and user constraints occur

Engineering Contradiction:

Improvesearch result quantityVSAvoiduseful information retrieval

Core Design Contradiction:

Quantity of substanceVSLoss of information

Solution Approach 1:

The patent implements dynamic filtering of search results based on user context such as location, movement state, and interaction behavior. The system dynamically adjusts which results are displayed and with what prominence, transforming a static large dataset into a dynamically optimized subset that maintains comprehensiveness while eliminating dead data.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent incorporates feedback mechanisms where user interactions (such as selecting a result, scrolling, or time spent viewing) provide information that refines subsequent result presentation. This feedback loop allows the system to learn user preferences and continuously optimize the balance between result quantity and usefulness, reducing dead data while preserving valuable information.

Inventive Principle:

Principle #23Feedback

3Reliability

If all search results are displayed on a map, then complete search coverage is achieved, but user ability to obtain desired results decreases

Engineering Contradiction:

Improvesearch result completenessVSAvoiddesired result acquisition

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent performs preliminary actions by pre-filtering and pre-organizing search results based on user location and contextual data before presentation. Results are pre-sorted by relevance and proximity, and potentially pre-grouped by category or location. This preliminary organization reduces the cognitive load on users and makes desired results immediately accessible without requiring users to manually search through all results.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent adds dimensional organization to search results beyond simple geographic mapping. Results are organized along multiple dimensions such as relevance score, category, distance, and user preferences. This multi-dimensional organization allows users to navigate results more efficiently by filtering or sorting along different dimensions, making desired results easier to acquire while maintaining complete coverage.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

Provided is a map service system and method for providing target content based on a location and/or position of a user device. The map service method includes identifying a pointer associated with a user device, the pointer indicating a position of the user device on a map. The method includes providing a spot finder in response to a position of the pointer, the spot finder having a desired radius based on a position of the pointer. The method includes providing a target content in the desired radius, the target content corresponding to a location within the desired radius.
