Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If UV lights are directly exposed to the sterilization occasion, then sterilization efficiency is improved, but human body safety deteriorates
Solution Approach 1:
The light body is divided into multiple light emitting grooves with light absorption layers between them, segmenting the UV radiation into controlled directional beams that sterilize the environment without directly exposing humans to harmful radiation
Solution Approach 2:
Light absorption layers are introduced as intermediary elements between the UV light source and the external environment. These layers selectively absorb UV radiation in certain directions while allowing sterilization radiation to reach the air and surfaces through the light emitting grooves
2Object-affected harmful factors
If a sealed cavity with fan air circulation is used, then human body safety is improved, but sterilization efficiency deteriorates
Solution Approach 1:
The grating structure allows dynamic control of UV radiation direction. The light emitting grooves can be oriented at different angles (horizontal or obliquely upward) to adapt to different installation environments and achieve both safety and sterilization effectiveness without requiring sealed enclosures
Solution Approach 2:
The invention transitions from a sealed 3D cavity approach to a directional 1D beam approach. UV rays are emitted through light emitting grooves in specific directions to directly irradiate the sterilization occasion outside the light body, eliminating the need for air circulation systems while maintaining safety
3Object-affected harmful factors
If sensing and control devices are added, then human body safety is improved, but device complexity deteriorates
Solution Approach 1:
The light absorption layers and grating structure passively control UV radiation direction without requiring active sensing or control systems. The structure itself serves the safety function by physically blocking UV rays in human-facing directions while allowing sterilization radiation to emit through the light emitting grooves
