Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light modifiers in the image capture industry lack versatility in creating varying lighting effects, are often bulky, and are not easily portable, limiting their application with different light sources and subjects.
Innovation Solution
A self-contained light modifier with a planar body, flexible frame, and adjustable aperture, featuring interchangeable reflective and absorptive surfaces, allowing for various lighting effects by positioning the modifier to absorb, reflect, or block light, and using additional panels for enhanced control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional light modifiers are used to create varying lighting effects, then lighting versatility is improved, but device weight and portability deteriorate
Solution Approach 1:
The light modifier is divided into separate functional panels (reflective panel and absorptive panel) that can be independently attached or removed from the frame, allowing the user to segment the modifier components based on lighting needs while keeping the overall structure lightweight
Solution Approach 2:
The single frame structure supports multiple types of panels (reflective and absorptive) that can be interchangeably attached, making the frame universal for creating different lighting effects with a single base unit, eliminating the need for multiple separate modifiers
2Adaptability or versatility
If traditional light modifiers are used to create varying lighting effects, then lighting versatility is improved, but device complexity and portability deteriorate
Solution Approach 1:
The modifier is segmented into a simple frame structure and interchangeable panel components, reducing overall structural complexity while maintaining versatility through modular assembly
Solution Approach 2:
A single universal frame design accommodates different panel types through standardized attachment mechanisms, simplifying the overall system while enabling multiple lighting functions without requiring complex specialized structures
3Illumination intensity
If direct light is used from the light source, then lighting intensity is improved, but shadow distinctness worsens
Solution Approach 1:
The planar body acts as an intermediary between the light source and subject, providing a reflective surface that redirects and softens direct light, thereby maintaining illumination intensity while reducing harsh shadow distinctness through the mediating reflective action
