Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the nock assembly is removed and re-installed to turn the LED on and off, then the LED can be controlled, but the operation becomes troublesome and inconvenient
Solution Approach 1:
The system automatically controls the LED power state based on the bowstring tension state. When the bowstring is pulled back, the nock body moves relative to the mounting base, automatically connecting the circuit to turn on the LED. When the arrow is released, the nock body returns to its original position, automatically disconnecting the circuit to turn off the LED. This eliminates the need for manual intervention to control the LED.
Solution Approach 2:
The patent introduces a dynamic sliding contact mechanism where the nock body can move relative to the mounting base along the arrow shaft. The conductive block within the nock body slides relative to the conductive mounting base, dynamically changing the electrical connection state between the battery and LED based on the mechanical position of the nock during arrow loading and release.
2Ease of operation
If the nock assembly is disassembled to replace the battery, then the battery can be replaced, but the operation becomes complex and time-consuming
Solution Approach 1:
The patent divides the nock system into separable components: the nock body containing the LED and conductive block, and the mounting base containing the battery compartment. The battery can be accessed and replaced by simply separating these two components along the arrow shaft, without requiring disassembly of the entire nock assembly or removal from the arrow.
3Illumination intensity
If the LED is always on to provide visibility, then tracking the arrow is easy, but the battery drains quickly
Solution Approach 1:
The LED operates periodically rather than continuously, turning on only when the bowstring is pulled back (loading phase) and turning off when the arrow is released (shooting phase). This periodic operation synchronized with the archery action significantly reduces battery power consumption while maintaining visibility when needed.
