Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile phones with 3D image functions face challenges in generating high-quality 3D images due to the close proximity of lens modules, which limits the viewing angle difference and increases manufacturing costs.
Innovation Solution
An electronic apparatus with a sliding structure that houses an optical module with two light-incidence openings spaced to match the average human eye distance, allowing for adjustable lens positioning to enhance viewing angle and image processing to form 3D images, while also incorporating a control module to switch between regular and 3D photography modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If two lens modules are disposed close to each other to maintain portability, then the device volume is reduced, but the viewing angle difference becomes insufficient affecting 3D image quality
Solution Approach 1:
The patent combines two lens modules into a single integrated lens module, where one lens captures light directly and the other lens captures light reflected at a specific angle. This merging approach eliminates the need for two separate lens modules while maintaining the dual-view capability for 3D image generation, thus reducing device volume while preserving 3D image quality
Solution Approach 2:
The patent introduces a reflective element as an intermediary component that redirects light at a specific angle to the second lens. This intermediary mechanism enables the second lens to capture light from a different viewing angle without requiring a second lens module positioned at a large distance, thereby achieving sufficient viewing angle difference within a compact form factor
2Adaptability or versatility
If another lens module is added to generate 3D images, then 3D image function is achieved, but the manufacturing cost increases
Solution Approach 1:
The patent merges the functionality of two separate lens modules into a single integrated lens module with multiple light-receiving surfaces. This consolidation reduces the number of components that need to be manufactured and assembled, thereby reducing manufacturing complexity and cost while maintaining the 3D image generation capability
Solution Approach 2:
The integrated lens module serves multiple functions: it captures light for regular imaging and simultaneously captures light for 3D imaging through its different light-receiving surfaces. This multi-functionality eliminates the need for a dedicated second lens module, reducing component count and manufacturing cost while achieving 3D image functionality
3Adaptability or versatility
If another lens module is added to generate 3D images, then 3D image function is achieved, but the available space in the mobile phone is reduced
Solution Approach 1:
The patent combines two lens modules into one integrated structure, significantly reducing the space required for the imaging system. This merging eliminates the need for a second lens module and its associated mounting space, thereby preserving available space within the mobile phone while achieving 3D image functionality
Solution Approach 2:
The patent utilizes the reflective element to redirect light at a specific angle, effectively using the third dimension (angle of incidence) to create a second light path. This dimensional approach allows the system to achieve dual-view capability without requiring a second lens module positioned at a large lateral distance, thus conserving available space
