Solution Overview

Problem

Conventional stamp rally systems provide rewards only when a player reaches all preset check points, limiting game flexibility.

Innovation Solution

A game system where players receive rewards and evaluation information based on reaching any check point, with rewards and evaluation determined by a combination of factors including check points, luck, and player selection, enhancing game flexibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the reward is provided only when the player reaches all preset check points, then the game rule is simple and clear, but the game flexibility is low

Engineering Contradiction:
Improvegame flexibilityVSAvoidevaluation system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The evaluation system is segmented into multiple independent evaluation factors: check point reachability (quantity), reward combination variety (quality), and player selection (subjectivity). Each factor can be weighted and combined flexibly to determine final evaluation results, allowing the system to adapt to different game scenarios without requiring complete check point completion.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The evaluation criteria are made dynamic by allowing the server to adjust the weightings and combinations of different factors based on game state, player performance, and predefined rules. The system can dynamically determine which factors matter most in different situations, providing flexibility while managing complexity through programmed decision logic.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If the reward is provided only when all check points are reached, then the incentive to complete the game is strong, but the participation barrier is high

Engineering Contradiction:
Improveparticipation easeVSAvoidevaluation fairness
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system applies partial action by providing rewards and evaluation opportunities even when players have not completed all check points. Players can receive partial evaluation results and rewards based on the subset of check points they have reached, reducing the participation barrier while maintaining evaluation fairness through proportional assessment of achieved objectives.

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The evaluation system changes parameters such as the threshold for reward eligibility and the weighting of different evaluation factors based on player progress and game state. This allows the system to adjust requirements dynamically, making participation more accessible while maintaining fair evaluation through transparent, rule-based assessment.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If the evaluation is based only on the number of reached check points, then the evaluation is simple and objective, but the game excitement is reduced

Engineering Contradiction:
Improveevaluation dimensionVSAvoidevaluation calculation complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The evaluation system uses composite materials by combining multiple evaluation dimensions (check point quantity, reward combination variety, player selection) into a comprehensive evaluation result. Each dimension contributes different characteristics to the final evaluation, creating a richer, more engaging assessment that reflects multiple aspects of player performance while using systematic combination methods to manage complexity.

Inventive Principle:
Principle #40Composite materials

AI summary

A processor of a game system acquires first positional information indicating a position of a mobile terminal that is acquired via a GPS receiver, determines whether the first positional information of the mobile terminal is contained in any of pieces of second positional information respectively corresponding to check points, and provides a reward as content of a game to a player corresponding to the mobile terminal every time the first positional information is contained in any of the pieces of second positional information. A memory stores evaluation corresponding information indicating a correlation between a combination of contents of rewards, and evaluation information including at least one of winning/losing, a ranking, and an earned point of the player in the game. The processor further determines the evaluation information of the player corresponding to the mobile terminal in the game based on the evaluation corresponding information according to the combination of the contents of provided rewards.
