Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Achieving suitable alignment between multiple camera parts in multi-part electronic devices is challenging due to tilt axis errors, especially when these parts are moved relative to each other.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple camera parts are mounted on separate device parts that can move relative to each other, then the device provides operational flexibility and additional focusing options, but alignment between camera parts becomes difficult to achieve and maintain
Solution Approach 1:
The resilient mount enables the camera part to self-align with the device part through elastic deformation. When the device parts move relative to each other, the resilient mount automatically adjusts the camera part's position to maintain proper alignment, eliminating the need for external adjustment mechanisms or complex mechanical linkages.
Solution Approach 2:
The resilient mount changes the mechanical parameters of the camera part mounting system by introducing elasticity. This allows the mounting structure to dynamically adjust its stiffness and positioning characteristics in response to relative movements between device parts, maintaining alignment within acceptable tolerances across different operational configurations.
2Stability of the object's composition
If camera parts are rigidly mounted to device parts, then alignment is stable, but the device cannot accommodate relative movement between parts for different operational modes
Solution Approach 1:
The resilient mount transforms the static, rigid mounting connection into a dynamic system that can adapt to relative movements between device parts. The elastic properties allow the mounting structure to flex and adjust in real-time, maintaining alignment stability while accommodating changes in device configuration for different operational modes.
Solution Approach 2:
The resilient mount functions as a flexible mounting element that can deform elastically to accommodate relative movements between device parts. This flexibility allows the system to maintain stable camera alignment while enabling the device to transition between different operational configurations, such as folded or extended states.
3Adaptability or versatility
If resilient mounts are used to allow relative movement between device parts, then operational flexibility is achieved, but alignment precision between camera parts deteriorates
Solution Approach 1:
The resilient mount enables the camera part to self-align with the device part through elastic deformation. When the device parts move relative to each other, the resilient mount automatically adjusts the camera part's position to maintain proper alignment, eliminating the need for external adjustment mechanisms or complex mechanical linkages.
Solution Approach 2:
The resilient mount replaces complex mechanical adjustment mechanisms with a simple elastic deformation system. This substitution maintains alignment precision by using the inherent elastic properties of the mounting material to automatically compensate for misalignment, avoiding the need for精密 mechanical linkages or adjustment screws.

Function Achieved in This Case
This solution effectively reduces tilt axis errors, ensuring accurate alignment of optical axes between camera parts, enhancing the overall camera system's precision and stability, even when parts are moved or overlapped.
Implementation Method 1
The first and second alignment members are magnetic. The first and second alignment members are positioned relative to each other such that a magnetic force capable of moving at least one of the first camera part or the second camera part is generated when the first and second device parts are overlapped with each other.
Implementation Method 2
The resilient mount can be configured to allow for translation of the respective camera part in lateral directions approximately perpendicular to an optical axis of the respective camera part.

AI summary
A multi-part electronic device has a mode with at least two overlapped device parts comprising a first camera part mounted on a first device part and a second camera part mounted on a second device part. At least one of the first and second camera parts is resiliently mounted such that contact between the first and second camera parts when the first device part and the second device part are overlapped with each other aligns the first camera part and the second camera part within a selected angular deviation between the camera parts' respective optical axes. A camera part having a body and a flexible mount and a method of reducing tilt error are also described.
