Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sharp dart tip is used to penetrate the dart target, then the dart can be stuck in the target groove, but the dart tip durability significantly decreases and breaks easily
Solution Approach 1:
The dart target is segmented into multiple replaceable units (first dart target unit and second dart target unit) that can be independently replaced when damaged, separating the durable target structure from the consumable dart tip
Solution Approach 2:
The dart target units are designed with different characteristics (first and second units with different properties) to allow optimization for different uses while maintaining the overall system functionality
2Ease of repair
If the dart target is repaired when the dart tip breaks, then the dart target can be restored, but the user must call a repair engineer and the apparatus cannot be used until repaired
Solution Approach 1:
The dart target system is divided into replaceable modules (dart target units and target cover units) that can be quickly swapped out, eliminating the need for complex repair operations and reducing maintenance downtime
Solution Approach 2:
The design enables users to easily replace dart target units and target cover units themselves without requiring professional repair engineers, allowing quick maintenance and continued usage
3Adaptability or versatility
If various components are installed in the dart game apparatus to meet different user preferences, then user customization is improved, but the device complexity and manufacturing burden increase
Solution Approach 1:
The dart target units and target cover units are designed as universal interchangeable components that can be used together in different combinations, allowing user customization without requiring multiple specialized components
Solution Approach 2:
The system allows dynamic reconfiguration by enabling users to swap between different dart target units and target cover units based on their preferences, providing adaptability through simple component interchange rather than complex multi-configuration design
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates quick and convenient replacement of dart targets and covers, reducing maintenance downtime and enhancing user customization options.
Implementation Method 1
The electronic dart game apparatus primarily has a piezoelectric element inside the dart target. In addition, in the dart game apparatus, a score of a dart game is counted by an electrical signal generated when a dart pin thrown by a user reaches the dart target and a change occurs in the piezoelectric element.
Implementation Method 2
at least one elastic member provided on the front surface of the body part and contacting the rear surface of the dart target unit through the opening unit, and the dart target unit may be in close contact with the target cover unit by restoration force of at least one elastic member
