Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current camera modules in electronic devices are limited to low-multiple zooming functions, resulting in a poor photographing effect that fails to meet user requirements.
Innovation Solution
A camera module design featuring a sliding mechanism where the camera and lens move between positions to achieve a high-multiple zooming function, with the lens and camera projections aligning or overlapping in the optical axis direction to allow light to pass through and improve image clarity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single camera or multiple cameras are used in conventional camera modules, then the device can implement basic photographing functions, but the zooming capability is limited to low-multiple zooming only
Solution Approach 1:
The patent implements a sliding mechanism that allows the lens and camera to move dynamically between different positions along the optical axis. This dynamic positioning enables the system to switch between low-multiple zooming mode (staggered projections) and high-multiple zooming mode (overlapping projections), thereby achieving versatile zooming capability while maintaining good photographing effect through precise positional control
Solution Approach 2:
The patent introduces a new spatial dimension for zooming by moving the lens and camera along the optical axis direction rather than relying solely on focal length adjustment. By controlling the relative positions in this additional dimension, the system achieves high-multiple zooming function while maintaining image quality, effectively resolving the contradiction between zooming capability and photographing effect
2Adaptability or versatility
If the camera and lens are positioned with staggered projections, then the structure is simpler, but high-multiple zooming function cannot be implemented
Solution Approach 1:
The patent employs a nested bracket structure where the second bracket is slidably sleeved on the first bracket, creating a compact nested arrangement. This nesting design allows the lens and camera to be positioned in overlapping projections for high-multiple zooming while keeping the overall structure compact and manageable, thus achieving high-multiple zooming function without excessive structural complexity
Solution Approach 2:
The sliding mechanism between the nested brackets enables dynamic repositioning of the lens and camera. This dynamic capability allows the system to switch between staggered and overlapping projection configurations, achieving high-multiple zooming function while maintaining reasonable structural complexity through a single degree of freedom movement
3Adaptability or versatility
If the lens and camera projections overlap in the optical axis direction, then high-multiple zooming function is achieved, but the structure becomes more complex
Solution Approach 1:
The nested bracket structure simplifies the implementation of overlapping projections by providing a pre-configured sliding guide. The second bracket slidingly sleeved on the first bracket creates a natural guide for the lens and camera movement, making the structural implementation straightforward while achieving the required overlapping projection configuration for high-multiple zooming
