Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional protective visor is used, then face protection is provided, but harmful rays cannot be effectively filtered out
Solution Approach 1:
The visor is divided into multiple functional components: face shield for general protection, protective goggles for eye protection, and light shading screen for ray filtering. Each component addresses specific protection needs, with the goggles containing lenses that can be adjusted to position in front of the eyes to block harmful rays effectively.
Solution Approach 2:
The protective goggles act as an intermediary element between the face shield and the operator's eyes. The goggles with specialized lenses filter harmful rays before they reach the eyes, while the adjustable mechanism allows the goggles to be positioned optimally in front of the eyes for maximum protection.
2Object-affected harmful factors
If fixed protective goggles are added, then eye protection is improved, but device complexity increases
Solution Approach 1:
The protective goggles are designed with adjustable mechanisms including guide rails and sliders that allow dynamic repositioning. The goggles can be moved up and down along the guide rails and fixed at different positions using sliders, enabling the operator to adjust the goggles to the optimal position for different working conditions.
Solution Approach 2:
The adjustable mechanism serves multiple functions: it allows the goggles to be positioned in front of the eyes for protection, moved to the top of the face shield when not needed, and adjusted to different heights for various operating conditions. This multi-functionality reduces the need for multiple separate protective devices.
3Object-affected harmful factors
If light refraction device with serrated lattice shutter structure is added, then glare reduction is improved, but device complexity increases
Solution Approach 1:
The light shading screen incorporates a localized serrated lattice shutter structure in specific areas to refract and diffuse harmful light while maintaining overall light transmission. The curved surface design of the light aperture with the shutter structure creates specific optical paths that reduce glare without blocking necessary visibility.
Solution Approach 2:
The light shading screen is made of dark colored translucent polycarbonate material that selectively absorbs and filters harmful wavelengths of light while allowing visible light to pass through. The dark coloration provides UV and blue ray protection while the translucent property maintains adequate light transmission for visibility.

AI summary
The disclosure provides a protective visor applicable to multiple operation environments for dust prevention, anti-shock glasses, chemical defense and ray radiation protection. The protective visor comprises a headband, a face shield, protective goggles, a light shading screen, a light grid and a housing, which are connected to each other. The light shading screen and the light grid constitute a light refraction and transmission device for refracting and transmitting the light, which includes a light aperture processed to have a curved surface and located at the front and upper end portion of the housing. The light aperture has a serrated lattice shutter structure, and the light shading screen is disposed at the outer side of the light aperture. The protective visor can effectively prevent foreign splash, and absorb radiant heat and certain ultraviolet rays to protect an operator's face.
