Lighted Nock External Switch Toggle Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing archery lighted nocks do not allow power to be turned off without a tool, and they lack an elongated light emitting device.
Innovation Solution
A lighted nock with an external switch, comprising a nock body, a light unit, a compression spring, and a pin battery, where the light unit includes a modified top hat LED, an LED housing, an LED housing insert, and a switch, allowing the power to be actuated without a tool through a toggle mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing lighted nocks are used, then the light source can illuminate the nock, but the power cannot be turned off without a tool
Solution Approach 1:
The nock performs its own switching function through the archer's interaction. When the archer draws the bowstring, it automatically actuates the switch mechanism to turn on the LED light, and when the string is released, the light turns off. This eliminates the need for separate manual switching operations or tools.
Solution Approach 2:
The switch mechanism transitions from a static design to a dynamic one that responds to the motion of drawing and releasing the bowstring. The switch is positioned and designed so that the natural movement of the string during archery operations automatically activates and deactivates the light source.
2Illumination intensity
If existing lighted nocks are used, then the light source illuminates the nock, but they lack an elongated light emitting device
Solution Approach 1:
The light source is divided into multiple LED segments arranged in an elongated configuration along the nock body. This segmentation allows the light to be distributed over a longer area, enhancing visibility from multiple angles while maintaining a compact overall structure that integrates with the nock.
