Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dart sharpening apparatuses require intricate setup and skilled operation, leading to potential damage and operator error when restoring game dart tips to their original dimensions, making them unsuitable for use during gameplay.
Innovation Solution
A dart restoration tool featuring a stator with a conical milling stone and a rotor that orbits the tip end of the dart, allowing for sharpening without complex setup, using a guide and journal mount to ensure precise engagement and adjustment for different tip lengths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If prior art dart sharpening apparatus are used, then dart tip sharpening can be achieved, but intricate setup and skilled operation are required leading to operator error and potential damage
Solution Approach 1:
The dart restoration tool allows the dart tip to sharpen itself through orbital motion against the milling stone, eliminating the need for operator skill in controlling the sharpening process. The guide member and journal mount automatically position and orient the dart tip correctly
Solution Approach 2:
The guide member and journal mount are pre-configured to automatically position and orient the dart tip at the correct angle and location relative to the milling stone before sharpening begins, eliminating setup complexity and ensuring consistent precision
2Manufacturing precision
If prior art dart sharpening apparatus are used, then dart tip restoration can be performed, but operator error can permanently damage the tip end
Solution Approach 1:
The system eliminates operator error by allowing the dart tip to self-sharpen through controlled orbital motion. The guide member and journal mount ensure the dart tip maintains the correct position and orientation throughout the process, preventing damage from improper operator technique
Solution Approach 2:
The journal mount with play and the guide member create a controlled, forgiving system that prevents excessive forces or misalignment from damaging the dart tip. The orbital motion path is predetermined and limited, cushioning against potential damage
3Manufacturing precision
If complex sharpening apparatus are used, then sharpening precision can be maintained, but the device cannot be used during gameplay
Solution Approach 1:
The invention extracts only the essential sharpening function from complex apparatus. The simple body, milling stone, guide member, and journal mount provide precise sharpening without unnecessary components, enabling portability and use during gameplay
Solution Approach 2:
The dart restoration tool is designed to be a self-contained unit that can be carried and used in various settings including during gameplay. The simple design allows it to serve multiple purposes while maintaining sharpening precision
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
The tool effectively sharpens dart tips to their original dimensions without operator error, enabling use during gameplay and maintaining performance without damaging the dart, as the conical milling surface and orbital motion ensure precise sharpening.
Implementation Method 1
The tip end is inserted into an annular cavity to frictionally engage the milling surface as the tip end orbits about the longitudinal axis

AI summary
A dart restoration tool includes a stator having a conical milling surface and a rotor mounted for rotation about a longitudinal axis of the stator. The rotor includes a guide adapted to accept a tip end portion of a game dart such that the tip end portion engages the conical milling surface. Rotation of the rotor about the longitudinal axis produces an orbital motion of the game dart against the conical milling surface to sharpen the tip end portion of the game dart.
