Cubic Corner Reflector Fishing Lure for Pressure Wave Reflection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fishing lures are ineffective in redirecting pressure waves generated by game fish back to the source, limiting their visibility and attractiveness to the fish.
Innovation Solution
Incorporating a cubic corner reflector with three substantially perpendicular, adjacent planar surfaces into fishing tackle, such as lures and sinkers, to reflect pressure waves back to the fish, enhancing their detection and attraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fishing lures are used, then the lure can be manufactured and deployed, but the pressure waves generated by fish are not reflected back to the fish, reducing detection effectiveness
Solution Approach 1:
The corner cube reflector creates an equipotential effect for pressure waves by ensuring that waves originating from any direction relative to the reflector are reflected back along their incoming path. The three perpendicular surfaces ensure that the optical path length is equal for all reflected rays, causing them to converge back to the source point, thereby enhancing detection effectiveness without requiring complex active sensing systems.
Solution Approach 2:
The corner cube reflector acts as an intermediary element between the fish-generated pressure waves and the fish's sensory systems. Instead of the fish directly detecting the lure through complex mechanisms, the reflector mediates by capturing outgoing pressure waves and redirecting them back to the fish, creating a feedback signal that enhances lure detection.
2Illumination intensity
If a cubic corner reflector is added to the lure, then pressure waves are reflected back to the fish improving visibility, but the device complexity increases
Solution Approach 1:
The corner cube reflector creates a virtual copy or image of the lure at the position of the fish by reflecting pressure waves back to their source. This optical copying effect allows the fish to perceive the lure's position and characteristics without the fish needing to physically approach or make direct contact, thereby enhancing visibility while maintaining a relatively simple physical structure.
Solution Approach 2:
The invention changes the acoustic parameter of pressure wave reflection by introducing surfaces with specific geometric parameters (three perpendicular planes at 90-degree angles). This parameter change in the lure's physical geometry creates the corner cube configuration that fundamentally alters how pressure waves interact with the lure, transforming it from a passive object to an active signal-reflecting structure that enhances visibility.

Function Achieved in This Case
The solution significantly increases the chances of a fish striking the lure by reflecting pressure waves towards the fish's lateral line sensory organs, creating an enticing pattern and increasing the lure's visibility.
