Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dartboards experience uneven wear and require frequent interruption for arrow removal, disrupting continuous training, and existing rotating dartboard solutions do not effectively address these issues.
Innovation Solution
A sports and gaming device with a rotatable target surface divided into equal circular sectors, equipped with an actuator, control device, and sensor that detects hits to rotate the target by a precise angular step, allowing for continuous training and even wear distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the dartboard is stationary, then the structure is simple and easy to manufacture, but the wear is uneven and training must be interrupted frequently
Solution Approach 1:
The dartboard is transformed from a stationary structure to a dynamic rotating structure. The rotation mechanism allows the target surface to be repositioned automatically or manually, enabling continuous training without interruption while maintaining relatively simple construction through the use of a turntable mechanism with support rollers and positioning features.
2Device complexity
If the dartboard is stationary, then the device complexity is low, but the service life is reduced due to uneven wear
Solution Approach 1:
By introducing rotation capability with a turntable mechanism, the dartboard can be repositioned to distribute wear across different areas of the target surface. The mechanism includes support rollers, positioning features, and a relatively simple actuation system that allows the dartboard to rotate without requiring complex mechanical structures.
3Reliability
If arrows are removed frequently, then the target surface can be maintained, but the training continuity is disrupted
Solution Approach 1:
The rotating turntable mechanism allows the dartboard to be repositioned to present a fresh, unworn portion of the target surface to the player. This dynamic repositioning capability maintains target quality and reliability for continuous training without requiring frequent arrow removal or board replacement.
4Productivity
If the dartboard rotates automatically, then the productivity increases, but the device complexity increases
Solution Approach 1:
The turntable mechanism incorporates a rotation drive system that can be actuated by a motor or manually. The positioning system includes features such as indexing mechanisms or sensors that detect when the dartboard has rotated to the correct position. This dynamic system enables automatic rotation and positioning, improving training efficiency while keeping the overall device complexity manageable through the use of standard motorized positioning components.
