Rotatable Light Module for Dual-Mode Beam Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light devices often require multiple units to cater to different lighting needs, which can be cumbersome and inefficient, especially for portable applications where users need to adjust lighting characteristics.
Innovation Solution
A light apparatus with a modular design featuring a light module, housing, and a direction switch structure that allows the light module to rotate between two housing sides, changing its light emitting direction to produce distinct light patterns with different characteristics, such as beam angle and intensity, using a rotation structure with shafts and slots, and optionally a stop mechanism for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple light devices are used to cater to different lighting needs, then lighting versatility is improved, but device portability and convenience deteriorate
Solution Approach 1:
The patent implements a single light device that can perform multiple lighting functions by rotating the light module to different positions. The light module can be oriented to provide different light patterns (e.g., focused beam vs. diffused light), replacing the need for multiple specialized light devices. This multi-functionality approach maintains lighting versatility while improving portability and convenience.
Solution Approach 2:
The patent employs a rotatable light module that can dynamically change its orientation and light emitting direction. The rotation mechanism allows the user to adjust the light module between different positions (e.g., facing first housing side or second housing side) to achieve different lighting effects. This dynamic adjustment capability enables one device to adapt to various lighting needs without requiring multiple fixed-function devices.
2Ease of operation
If a single light device is used, then device portability is improved, but lighting versatility deteriorates
Solution Approach 1:
The single light device incorporates a rotatable light module that can be positioned in multiple orientations, each producing different light patterns. This allows one portable device to replace multiple specialized devices by providing versatile lighting options through mechanical reconfiguration rather than requiring multiple separate units.
Solution Approach 2:
The rotatable light module enables the single device to dynamically adapt its lighting characteristics by changing orientation. The user can rotate the light module to face different housing sides, transforming the device from a fixed-function unit to a versatile, adjustable lighting solution that maintains portability while achieving multiple lighting effects.
3Device complexity
If the light module is fixed in the housing, then device simplicity is improved, but lighting adaptability deteriorates
Solution Approach 1:
The patent introduces a rotation mechanism that allows the light module to change its orientation relative to the housing. This dynamic element enables the light module to be positioned in different configurations (e.g., facing first or second housing side), providing lighting adaptability while maintaining relatively simple device architecture through a straightforward rotational joint and positioning structure.

AI summary
A light apparatus has a light module, a housing, and a direction switch structure. The light module has a light source. The light source emits light to a light emitting side of the light module. The housing stores the light module and has a first housing side and a second housing side. The direction switch structure is used by user for switching the light emitting side facing to the first housing side or the second housing side. When the light emitting side of the light module faces to the first housing side, a first light pattern is output by the light apparatus. When the light emitting side of the light module faces to the second housing side, a second light pattern is output by the light apparatus. The first light pattern and the second light pattern have different light characteristics.
