Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the pushing portion of the ejector mechanism is placed closer to the Bowens Mount, then the structure is more compact, but the operation becomes inconvenient when accessories are installed
Solution Approach 1:
The patent relocates the pushing portion from a position near the Bowens Mount to a position on the rear surface of the housing, changing its spatial dimension. This dimensional relocation allows the pushing portion to be accessed from behind the lamp, away from the accessory mounting area, thereby eliminating interference from accessories while maintaining structural compactness.
2Area of stationary object
If the photography lamp and accessories become larger, then the lighting coverage is improved, but the ejector rod sliding operation is interfered by the accessories
Solution Approach 1:
The patent extracts the pushing portion from the vicinity of the accessory mounting area and relocates it to the rear surface of the housing. This extraction removes the source of interference from the accessory installation zone, allowing large accessories to be mounted without obstructing the ejector rod sliding operation.
3Ease of operation
If the ejector rod is positioned to facilitate easy access, then the operation is convenient, but it becomes interfered by accessories installed on the lighting device
Solution Approach 1:
The patent positions the pushing portion on the rear surface of the housing, utilizing the rear dimensional space rather than the front or side areas where accessories are mounted. This dimensional placement ensures that the pushing portion remains accessible and free from interference by accessories of various sizes.
