Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current path lights have a fixed illuminated spot size, which is inconvenient for adjusting to meet varying needs in illuminating small roads in parks and gardens.
Innovation Solution
A focus-adjustable lamp design featuring a light-emitting element, a shield body, a heat dissipating member, and a light-converging cylinder that can rotate to adjust the size of the light spot projected on the ground, allowing for precise adjustment of the light spot's size based on the operational environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the light spot size is fixed in conventional path lights, then the structure is simple and easy to manufacture, but the adaptability to different illuminating needs is poor
Solution Approach 1:
The patent applies the dynamics principle by making the light-converging cylinder rotatable relative to the shield body. This rotation allows the light spot size to be dynamically adjusted between concentrated and dispersed states, transforming a static fixed-spotlight structure into a dynamic adjustable one, thereby resolving the contradiction between structural simplicity and adaptability.
2Adaptability or versatility
If a light-converging cylinder is added to enable focus adjustment, then the adaptability improves, but the device complexity increases
Solution Approach 1:
The light-converging cylinder serves multiple functions: it converges light to adjust spot size, provides structural support, and enables rotation for focus adjustment. By making one component perform multiple functions, the patent adds focus adjustment capability without proportionally increasing overall device complexity.
Solution Approach 2:
The light-converging cylinder is rotationally sleeved on the outer side of the shield body, with the shield body's outer wall rotationally matched with the light-converging cylinder. This nested arrangement allows compact integration of multiple components, reducing space occupation and simplifying the overall structure while maintaining adjustability.
3Ease of operation
If the light-converging cylinder rotates to adjust light spot size, then the usability improves, but the manufacturing precision requirements increase
Solution Approach 1:
The patent changes the operational parameter from fixed to adjustable by enabling rotation of the light-converging cylinder. This allows users to adjust the light spot size parameter according to different environmental needs, improving ease of operation. The rotational matching between the shield body outer wall and light-converging cylinder provides a mechanical guide that facilitates smooth adjustment while maintaining acceptable manufacturing tolerances.
