Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing deterrent devices for repelling noise- and vibration-sensitive pests face energy supply limitations, particularly on cloudy days, which can hinder effective deterrence due to insufficient power generation from photovoltaic elements.
Innovation Solution
The deterrent device features a translucent cover with optical structures such as light-refracting edges and light-bundling bulges that direct incident light towards flat plate photovoltaic elements, positioned within a dome-shaped cover, enhancing light output and energy production, and includes a cylindrical shaft with rechargeable batteries for improved power supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If photovoltaic elements are used for energy generation in deterrent devices, then energy production is enabled, but energy supply is insufficient on cloudy days or under low solar radiation
Solution Approach 1:
The patent applies a dome-shaped cover instead of a flat cover over the photovoltaic elements. This curved surface optimizes light reflection and refraction, directing more incident light onto the photovoltaic elements regardless of the angle of sunlight. The dome shape effectively concentrates light onto the flat plate photovoltaic elements, significantly improving energy generation efficiency under various lighting conditions including cloudy days and low solar radiation.
Solution Approach 2:
The patent changes the optical parameters of the cover by incorporating light-refracting edges and light-bundling bulges. These optical structures modify the path and distribution of light rays, redirecting them onto the photovoltaic elements. The prismatic or faceted structures on the cover surface alter light refraction and reflection characteristics, maximizing light capture efficiency and ensuring reliable energy supply even under challenging environmental conditions.
2Power
If the deterrent device operates more intensively with higher noise or vibration, then deterrence effectiveness is improved, but energy consumption increases
Solution Approach 1:
The dome-shaped cover optimizes the capture of incident light onto the photovoltaic elements, maximizing energy generation capacity. This increased energy availability enables the device to operate at higher power levels for longer durations, supporting more intensive noise and vibration generation without compromising energy supply stability.
Solution Approach 2:
The optical structures (light-refracting edges, light-bundling bulges, prismatic patterns) on the cover modify light propagation parameters to concentrate more sunlight onto the photovoltaic elements. This enhances the electrical energy output, providing sufficient power for intensive deterrence operations even under reduced solar radiation conditions.
3Device complexity
If the photovoltaic elements are positioned flat under the cover, then the structure is simple, but light output efficiency is reduced
Solution Approach 1:
The dome-shaped cover creates an optimized optical environment that directs light onto the flat plate photovoltaic elements positioned within the dome. The curved surface acts as a light-concentrating structure, ensuring that even flat-mounted photovoltaic elements receive maximum light intensity. This maintains structural simplicity while dramatically improving energy generation efficiency.
Solution Approach 2:
The cover is designed with integrated optical structures (light-refracting edges, light-bundling bulges, prismatic patterns) that segment and redirect light rays onto the photovoltaic elements. These segmented optical features work together to concentrate light efficiently, improving output without requiring complex mechanical adjustments or multiple photovoltaic layers.
