Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hair removing devices generate excessive heat, leading to reduced lamp life and potential skin burns, and often produce uneven light output, with trigger wires failing to consistently activate the lamp.
Innovation Solution
A hair removing device with a reflector that reflects light from a strip-shaped gas excitation light source, enhancing heat dissipation through a carbon-containing layer and optimizing the distance between the light source and reflector to ionize gas for arc light discharge, eliminating the need for a triggering line and improving light uniformity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the lamp operates to provide hair removal function, then hair removal efficiency is improved, but heat accumulates reducing lamp service life and causing skin burns
Solution Approach 1:
The patent extracts the harmful heat from the system by introducing a dedicated heat dissipation pathway. The heat dissipation component is positioned to receive heat from the lamp, separating the light emission function from heat management, allowing the lamp to operate at high efficiency while heat is actively removed through conduction and radiation.
Solution Approach 2:
The patent introduces a heat dissipation component as an intermediary between the lamp and surrounding structures. This intermediary component facilitates heat transfer from the lamp to the environment, mediating the thermal interaction and preventing heat accumulation that would otherwise reduce lamp life and cause skin burns.
2Ease of operation
If a trigger wire is used to activate the lamp, then the lamp can be controlled, but the contact reliability between trigger wire and lamp is poor increasing activation cost
Solution Approach 1:
The patent replaces the mechanical trigger wire contact system with an electromagnetic field-based activation system. The reflector serves dual functions: reflecting light and generating an electromagnetic field that reliably activates the lamp without requiring physical contact, eliminating the reliability issues of mechanical contact while maintaining ease of operation.
Solution Approach 2:
The patent makes the reflector multi-functional by enabling it to serve both as a light reflector and as an electromagnetic field generator for lamp activation. This eliminates the need for a separate trigger mechanism, improving reliability while maintaining operational simplicity.
