Lighted Arrow Nock One-Touch Lamp Off Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional arrows with light-emitting functions require complex structures and tools to turn off the luminous lamp after shooting, leading to inefficient battery consumption.
Innovation Solution
A lighted nock design featuring an upper and lower body housing, a push member, a luminous lamp assembly, a battery assembly, a turning off switch housing, and a push button, allowing the luminous lamp to be turned off by moving the luminous lamp assembly backward and breaking contact with the battery when the push button is pressed.

Engineering Contradiction Analysis
1Duration of action of moving object
If the luminous lamp is kept turned on until artificially turned off, then the light emitting function is maintained, but the battery is consumed excessively
Solution Approach 1:
The luminous lamp operates in periodic cycles: automatically turns on when the arrow is shot (push member moves forward), remains on during flight, then automatically turns off after a set period or when the arrow comes to rest. This periodic operation pattern allows the lamp to emit light only when needed during the arrow's flight, avoiding continuous battery drainage while maintaining effective illumination during the critical observation period.
2Ease of operation
If a separate mechanism is used to turn off the luminous lamp, then the lamp can be turned off, but the structure of the nock becomes complicated
Solution Approach 1:
The patent merges the lamp turning-off function with the existing push member mechanism that is already used to turn on the lamp. The same push member, when moved backward (either automatically by string tension or manually by the archer), simultaneously breaks the electrical contact to turn off the lamp. This integration eliminates the need for separate turning-off mechanisms, switches, or buttons, thereby simplifying the overall nock structure while maintaining ease of operation.
Solution Approach 2:
The system is designed to turn off the luminous lamp automatically through the natural backward movement of the push member, which occurs either due to string tension after shooting or manual release by the archer. This self-service mechanism eliminates the need for additional manual intervention or complex control systems, allowing the lamp to turn off seamlessly as part of the normal arrow handling process.
3Ease of operation
If a fine tool such as a small-sized driver is used to turn off the luminous lamp, then the lamp can be turned off, but the operation becomes inconvenient
Solution Approach 1:
The system automatically turns off the luminous lamp through the backward movement of the push member, which is naturally caused by string tension after the arrow is shot or by simple manual release. This eliminates the need for the archer to use fine tools like small drivers, saving both time and effort. The lamp turns off as part of the normal arrow handling process without requiring any specialized tools or complex manual operations.

AI summary
The present invention relates to a lighted nock for an arrow, and more particularly, to a lighted nock for an arrow that is configured to simply and easily turn off a luminous lamp without using a separate mechanism when an internal luminous lamp of the lighted nock is turned on by shooting the arrow and then turning off the luminous lamp again.
