Lighted Arrow Nock Self-Service Switch Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighted arrows with luminous functions require complex structures and tools to turn off the luminous lamp after shooting, leading to inconvenient battery consumption.
Innovation Solution
A lighted nock design featuring a turning off switch housing and push buttons that allow the luminous lamp assembly to move out of contact with the battery assembly when pressed, enabling a simple one-touch operation to turn off the lamp.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the luminous lamp is kept turned on after shooting until artificially turned off, then the arrow can be used for night archery, but the battery is consumed and the structure to turn off the lamp becomes complicated
Solution Approach 1:
The system uses the kinetic energy from the arrow's motion itself to automatically turn off the luminous lamp. The moving part of the arrow mechanically actuates the switch during flight, eliminating the need for separate manual operation or additional tools, thus resolving the contradiction between battery conservation and ease of operation.
Solution Approach 2:
The switch mechanism is designed to be dynamically actuated by the arrow's motion during flight. The switch housing and contact arrangement are configured so that the arrow's movement automatically opens the circuit, transforming the operational state from static manual control to dynamic automatic control based on the arrow's kinetic state.
2Ease of operation
If a separate mechanism is used to turn off the luminous lamp, then the lamp can be controlled, but the structure of the nock becomes complicated and requires fine tools for operation
Solution Approach 1:
The switch mechanism is integrated directly into the nock structure, merging the lamp control function with the existing nock components. The switch housing, contact arrangement, and actuation mechanism are combined within the nock assembly, eliminating the need for separate external mechanisms or fine tools, thus reducing overall device complexity while maintaining ease of operation.
Solution Approach 2:
The arrow's own motion serves to actuate the switch mechanism, using the kinetic energy already present in the system rather than requiring external actuation tools. This self-actuating approach eliminates the need for separate control mechanisms or fine tools, directly reducing device complexity while preserving operational ease.
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
Enables easy and efficient turning off of the luminous lamp without the need for additional tools, conserving battery life by allowing users to deactivate the light with minimal effort.
Implementation Method 1
a turning off switch housing (400) mounted between the upper body housing (200) and the lower body housing (300) and moving in a forward direction due to the tension of a string when the arrow is shot

AI summary
Disclosed is 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.
