Innovation Solution
A lamp head connection structure featuring a spherical recess structure on the connection seat and a compatible sphere on the connection member, allowing 360° rotation and detachable connection between the lamp body and lamp head, facilitated by a clamping part with notches and locking members for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed lamp head rotating structure is used, then multi-angle illumination is achieved, but detachable connection between lamp head and lamp base is not possible
Solution Approach 1:
The connection structure is divided into separate components: a connection member with spherical recess on the lamp body, and a connection seat with spherical protrusion on the lamp head. This segmentation enables detachable connection while maintaining rotational functionality, resolving the contradiction between adaptability and device complexity.
Solution Approach 2:
The connection mechanism uses spherical geometry - a spherical recess配合 spherical protrusion - to enable 360° rotation and detachable connection. The spherical shape allows rotational movement in multiple directions while maintaining a simple, elegant connection structure that achieves both adaptability and simplicity.
2Volume of moving object
If the lamp head is permanently attached, then structural stability is maintained, but space-saving and convenient transportation are compromised
Solution Approach 1:
The connection seat is designed to be embedded within the lamp head housing, creating a nested structure where the connection components are integrated into the lamp head body. This nesting approach maintains structural stability when connected while enabling compact storage when detached, achieving both space efficiency and reliability.
Solution Approach 2:
The spherical connection interface provides inherent stability through its geometry - the spherical protrusion fits into the spherical recess with clearance for rotation but sufficient contact area to maintain reliable connection. This spherical design ensures stable connection during use while allowing easy detachment for compact storage.
3Ease of operation
If a traditional rotating mechanism is used, then illumination angle adjustment is achieved, but 360° rotation capability is limited
Solution Approach 1:
The spherical connection interface naturally enables 360° rotation in multiple directions without requiring complex mechanical mechanisms. The spherical geometry provides freedom of movement while maintaining a simple connection structure, achieving high rotation flexibility with minimal complexity.
Solution Approach 2:
The separation of the connection member and connection seat creates an independent rotating interface that allows the lamp head to rotate 360° relative to the lamp body. This segmented design provides full rotational freedom without the need for complex gears, bearings, or other mechanical rotation mechanisms.
