Solution Overview

Problem

Existing flag systems do not provide customizable difficulty levels for flag separation, making it difficult for players of varying ages and skill levels to compete fairly and engage in more interesting gameplay.

Innovation Solution

The flag system allows for user-selectable levels of difficulty by adjusting flag configuration, including flag shape, length, and connection methods, providing different resistance levels for flag pulling, and ensuring consistent flag positioning during gameplay.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If flag systems use fixed connection methods, then manufacturing is simple, but adaptability to different skill levels is poor

Engineering Contradiction:
Improveadaptability to different skill levelsVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The flag connection system transitions from static fixed connections to dynamic adjustable connections. The flag coupler can be repositioned along the flag carrier at different locations, and the connection strength can be varied by changing the insertion depth into the hollow tube, allowing the same device to adapt to different skill levels and player needs.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system allows changing key parameters of the flag connection: the position of the flag coupler along the carrier and the depth of insertion into the hollow tube. By adjusting these parameters, the resistance to flag pulling can be modified, enabling customization for different skill levels without changing the fundamental device structure.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If flag systems provide customizable difficulty levels, then adaptability improves, but device complexity increases

Engineering Contradiction:
Improvecustomizable difficulty levelsVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The flag system is designed as a universal device that can serve multiple functions and accommodate different skill levels. The same flag carrier, hollow tube, and coupler assembly can provide varying degrees of difficulty by simply adjusting the coupler position and insertion depth, eliminating the need for multiple specialized devices for different skill levels.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The flag connection system is segmented into adjustable components: the flag carrier with multiple positioning locations, the hollow tube with variable insertion depth, and the movable coupler. This segmentation allows independent adjustment of each component to achieve the desired difficulty level while maintaining overall system simplicity.

Inventive Principle:
Principle #1Segmentation

3Stability of the object's composition

If flag connection is made more secure, then flag positioning consistency improves, but ease of legitimate flag pulling decreases

Engineering Contradiction:
Improveflag positioning consistencyVSAvoidease of legitimate flag pulling
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The connection system provides dynamic balance between security and accessibility. The hollow tube and coupler design allows the flag to remain securely positioned during normal play through friction and geometric fit, while still permitting legitimate flag pulling when sufficient force is applied, as the coupler can be extracted from the tube.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system allows adjustment of the connection strength parameter by varying the insertion depth of the coupler into the hollow tube. Deeper insertion provides greater positioning consistency and security, while shallower insertion maintains ease of legitimate flag pulling, allowing optimization based on specific gameplay requirements.

Inventive Principle:
Principle #35Parameter changes

AI summary

A flag system includes a flag carrier and a flag unit. The flag unit includes a flag, and a flag coupler connected to the flag and configured to be releasably connected to the flag carrier. The flag unit is user reconfigurable between a first flag unit separation difficulty state and a second flag unit separation difficulty state.
