Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Motion sensing lighting devices face challenges in achieving adjustable detecting ranges and lighting angles while simplifying assembly procedures, which are complex and prone to moisture ingress due to axles, increasing assembly time and labor, and requiring multiple components.
Innovation Solution
A motion sensing lighting device with a base seat and an illuminating assembly featuring a pivotal portion, an adapter module, and hinge modules that allow for adjustable lighting angles and simplified assembly through a single pivotal axis connection, reducing the need for screws and enhancing water-proofing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If multiple lights are equipped to achieve wider illuminating angle, then the illuminating angle is improved, but the device complexity and assembly procedures increase
Solution Approach 1:
The patent combines multiple illumination lamps into a single integrated illuminating assembly that is pivotally connected to the base seat by a single axle. This merging approach allows multiple lights to work together for wider illumination coverage while avoiding the complexity of multiple separate assemblies, as all lights share common mounting structure and adjustment mechanisms.
Solution Approach 2:
The single pivotal axle serves multiple functions: it supports the entire illuminating assembly, enables adjustment of lighting angles, and provides a unified mounting interface for multiple lamps. This universal component reduces the need for separate mounting mechanisms for each light, thereby simplifying assembly procedures.
2Ease of operation
If axles are used to connect lights to base seat, then the illuminating angle is adjustable, but the risk of moisture entering base seat increases
Solution Approach 1:
The patent employs sealing structures (such as sealing rings or gaskets) at the pivotal connection points between the axle and base seat to create protective barriers against moisture. These sealing elements flex with the rotational movement while maintaining the seal, allowing adjustability while preventing moisture ingress into the base seat.
3Ease of manufacture
If traditional assembly methods are used, then the device is functional, but the assembly time and labor increase
Solution Approach 1:
The patent divides the illuminating assembly into modular components (individual lamps, housing, pivotal connection) that can be assembled in a systematic sequence. This segmentation allows for standardized assembly procedures and facilitates parallel processing of components, thereby reducing total assembly time while maintaining functional integrity.
