Lighting Apparatus Middle Connection Unit with Arc Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting apparatuses with middle connection units are structurally limited, making it difficult for users to conveniently and smoothly move the position of the lighting unit due to inadequate relative movement between rod-shaped members.
Innovation Solution
A lighting apparatus with a middle connection unit featuring rotatable frames, guide elongate holes, and a guide pin unit allows for easy and convenient movement of the second rod-shaped member with respect to the first, incorporating an elastic supporting unit and inclined plane to facilitate smooth positioning changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional middle connection unit is used to connect the first and second rod-shaped members, then the structural simplicity is maintained, but the ease of operation deteriorates because the user cannot conveniently move the position of the lighting unit
Solution Approach 1:
The guide pin is nested within the guide elongate hole, with the guide pin unit movable along the arc-shaped guide hole. This nesting structure allows the second rod-shaped member to rotate relative to the first rod-shaped member through a limited angle while maintaining structural compactness, thereby improving ease of operation without significantly increasing device complexity
Solution Approach 2:
The guide elongate hole is formed with an arc shape instead of a straight line. This curved geometry enables the guide pin to follow a rotational path, allowing the second rod-shaped member to rotate relative to the first rod-shaped member. The arc-shaped guide hole provides smooth rotational movement while constraining the rotation to a limited angle, improving operational convenience
2Ease of operation
If the middle connection unit allows greater relative movement between rod-shaped members, then the ease of operation improves, but the stability of the lighting unit deteriorates
Solution Approach 1:
The middle connection unit is designed with dynamic characteristics through the elastic supporting unit that can elastically support the second rod-shaped member. This allows the connection unit to adapt to movement requirements while maintaining stability through elastic resistance, enabling smooth positioning changes without compromising structural stability
Solution Approach 2:
The middle connection unit is segmented into distinct functional components: the first frame, second frame, guide pin unit, and elastic supporting unit. This segmentation allows each component to perform its specific function - the guide pin unit enables rotation, while the elastic supporting unit maintains stability - thereby achieving both ease of operation and position stability
3Ease of operation
If more guide elongate holes are provided in the middle connection unit, then the ease of operation improves, but the device complexity increases
Solution Approach 1:
Instead of providing multiple guide elongate holes, the invention uses a single arc-shaped guide elongate hole that provides sufficient rotational movement capability. This partial action approach achieves the necessary positioning flexibility without the complexity of multiple guide holes, as the arc shape alone enables the required range of motion
