Solution Overview
Problem
Existing lighting devices with optical elements face challenges in accurately aligning and compensating for assembly defects due to form-fit connections, which restrict movement and positioning of optical elements.
Innovation Solution
Incorporating a spring element as a fastening region that allows for force-fit fastening in at least one direction, enabling the optical unit to be moved and self-adjusted without external intervention, thereby simplifying alignment and compensating for positioning defects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a form-fit connection is used to fasten the optical element, then the optical element is securely held in position, but assembly defects and positioning errors cannot be compensated for
Solution Approach 1:
The patent transitions from a static form-fit connection to a dynamic spring element connection that allows controlled movement. The spring element enables the optical unit to move and self-adjust during assembly while maintaining secure fastening, thus compensating for positioning errors without losing stability.
Solution Approach 2:
The spring element changes the mechanical parameters of the fastening system by introducing elastic deformation capability. This allows the fastening force to vary dynamically during assembly, enabling the optical unit to move into correct position while being held securely by the spring force.
2Manufacturing precision
If spring elements are added to a form-fit connection to compensate for assembly defects, then movement compensation is possible, but the alignment process becomes more complex
Solution Approach 1:
The patent combines the fastening function and the alignment compensation function into a single spring element structure. The spring element simultaneously provides secure fastening and enables movement for alignment, eliminating the need for separate adjustment mechanisms and reducing overall complexity.
Solution Approach 2:
The spring element enables self-alignment of the optical unit during assembly. The optical unit can move freely along the spring element's direction of force-fit fastening and automatically positions itself correctly without requiring external adjustment tools or complex alignment procedures.
3Stability of the object's composition
If the optical element is held with a form-fit connection, then positioning is fixed, but external adjustment mechanisms are required to correct positioning errors
Solution Approach 1:
The spring element enables the optical unit to self-adjust and self-align during assembly. The optical unit moves automatically along the spring element's direction under the spring force, finding its correct position without requiring external adjustment mechanisms or manual intervention.
Solution Approach 2:
The system transitions from a fixed form-fit connection to a dynamic spring-based connection that allows controlled movement. This dynamic capability enables the optical unit to move into correct position during assembly while the spring force maintains stable fastening, eliminating the need for external adjustment.
