Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic apparatuses with projectors are limited in their ability to independently rotate and focus images across a wide area due to fixed directional components, leading to incomplete projection regions and reduced image quality.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the projector direction is fixed, then the device structure is simple, but the projection region is limited
Solution Approach 1:
The projector module is made rotatable around a second axis perpendicular to the first axis, enabling dynamic adjustment of the projection direction. This allows the projector to cover multiple regions by changing its orientation rather than requiring multiple fixed projectors, thus expanding projection region coverage while maintaining relatively simple device structure.
Solution Approach 2:
The device is divided into separate functional modules: a first housing that rotates around the first axis and a projector module that rotates independently around the second axis. This segmentation allows each module to be optimized for its specific function while working together to achieve comprehensive projection coverage.
2Adaptability or versatility
If the sensor and projector drive in the same direction, then the structure is simple, but they cannot independently perform recognition and projection functions
Solution Approach 1:
The vision sensor module and projector module are equipped with independent driving mechanisms. The vision sensor rotates around the first axis independently, while the projector rotates around the second axis independently. This independence allows each component to perform its function (recognition and projection) without being constrained by the other's movement, enabling simultaneous and coordinated operation.
Solution Approach 2:
The vision sensor and projector operate in different rotational dimensions: the vision sensor rotates around the first axis (let's call it the pitch axis), while the projector rotates around the second axis (the roll axis). This dimensional separation allows both components to move independently in their respective directions, achieving functional independence while maintaining a coordinated spatial relationship.
3Manufacturing precision
If one lens is used for the entire projection region, then the device is simple, but some regions are not focused
Solution Approach 1:
The single lens is divided into multiple micro lenses arranged in an array. Each micro lens corresponds to a specific region of the projection surface, allowing independent focus adjustment for each region. This segmentation enables precise focusing across the entire projection area without requiring a complex adjustable lens system, as each micro lens independently optimizes focus for its designated region.
Solution Approach 2:
Different regions of the projection surface are served by different micro lenses, each optimized for its local area. This allows each region to receive focused light according to its specific requirements, improving overall image quality across the entire projection region while maintaining a relatively simple lens structure through the use of identical micro lens units.
