Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a laser emitting dart apparatus is introduced to improve aiming accuracy, then the dart-throwing accuracy is enhanced, but the device complexity increases due to additional electronic components
Solution Approach 1:
The laser emitting dart apparatus is nested within a charging case that also functions as a storage container. The charging case contains inductive charging coils and control circuitry that are integrated into the case structure, allowing the dart to be recharged simply by being placed in the case without requiring separate charging equipment or complex user operations.
Solution Approach 2:
The charging case automatically detects when a laser emitting dart is placed within it and initiates the recharging process through inductive coupling. The system self-regulates the charging process, eliminating the need for manual intervention or complex user操作流程. The dart automatically receives power from the case's battery through the inductive charging mechanism.
2Ease of operation
If a charging case with inductive charging coils is used to facilitate convenient recharging, then the ease of operation is improved, but the device complexity increases due to additional charging components
Solution Approach 1:
The charging case combines multiple functions into a single device: it serves as a storage container for the laser emitting darts, a charging station with inductive charging coils, and a power source. The case's battery is integrated with the charging mechanism, eliminating the need for separate chargers or power banks. This merging of functions simplifies the user experience while consolidating components into a unified system.
Solution Approach 2:
The charging case acts as an intermediary between the power source and the laser emitting dart. Instead of requiring direct connection or complex charging procedures, the case provides a simplified interface where the user only needs to place the dart in the case for automatic recharging. The inductive charging coils in the case mediate the power transfer, abstracting away the complexity of battery management and charging control from the user.

AI summary
Disclosed is a laser emitting dart apparatus (LEDA) and method of use. The LEDA provides for a dart apparatus that, by emitting a laser beam from a tip of the dart and projecting a laser dot onto a selected target, facilitates a dart user's aim by providing an indication of where the dart is likely to strike a selected target if the dart is thrown or projected in a substantially straight line from point of the user's grasp to the indicated laser dot projected onto the target. The invention further contemplates various charging cases or dart cradles that provide an electrical source to recharge a battery of the LEDA when the LEDA is not in use.
