Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional light-direction adjustment devices occupy additional space during angle adjustments, making them unsuitable for narrow environments and requiring improved heat dissipation and sealing to prevent dust and moisture ingress.
Innovation Solution
A light-direction adjustment device with a curved adjustment unit that fits within a receiving chamber, featuring synchronized first and second driving members, heat dissipating elements, and sealing members to maintain stability and prevent space occupation during adjustments, while ensuring efficient heat dissipation and protection from environmental pollutants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the lamp body performs a rotating movement relative to the supporting component to change light direction, then the light emission direction can be adjusted, but the device occupies additional and constantly changing space
Solution Approach 1:
The adjustment unit is nested within the lamp body, with the curved adjustment unit fitting inside a receiving chamber formed by the lamp body and housing. This nesting arrangement allows the adjustment mechanism to be contained within the existing device volume, preventing additional space occupation during angle adjustments while maintaining full light direction adjustability.
Solution Approach 2:
The adjustment unit employs a curved structure that coordinates with the curved first and second driving surfaces. This curved geometry enables compact packaging of the adjustment mechanism within the receiving chamber, allowing the lamp body to rotate through various angles while maintaining a compact overall form factor that does not expand the device envelope.
2Volume of moving object
If the adjustment unit is designed with curved structures to fit within the receiving chamber, then space occupation is minimized, but the manufacturing complexity increases
Solution Approach 1:
The adjustment unit and driving surfaces utilize curved geometries that are consistent with conventional molding and machining techniques. The curved adjustment unit, first curved driving surface on the housing, and second curved driving surface on the lamp body can be manufactured using standard industrial processes, balancing the compact space-saving design with manufacturing feasibility.
3Reliability
If the device is designed for outdoor or polluted environments, then durability is improved, but sealing requirements and device complexity increase
Solution Approach 1:
The device incorporates sealing members that form protective barriers between the adjustment unit and the external environment. These sealing structures, integrated into the housing and lamp body assembly, prevent dust and moisture ingress without requiring complex separate sealing components, maintaining reliability while controlling overall device complexity.
