Camera Positioning Member for Light-Window Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The issue of camera eccentricity relative to the light-transmitting window in electronic devices, such as mobile phones and tablets, leads to reduced appearance fineness due to poor stability in the circumferential limiting structure, causing misalignment of the camera's light-incident surface with the window's center.
Innovation Solution
A positioning member with a compressible capability that increases from one end to the other, allowing the camera to tilt and adjust its position to align with the light-transmitting window, utilizing elastic-plastic materials and flexible structures to compensate for deviations and maintain alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a circumferential limiting structure is used to position the camera, then the camera position is constrained, but the structure lacks stability causing eccentricity
Solution Approach 1:
The patent changes the physical state of the positioning member from rigid to elastic, allowing it to deform under compression. This enables the member to absorb position deviations through elastic deformation while maintaining stable contact with the camera body, thereby improving alignment precision without compromising structure stability.
Solution Approach 2:
The positioning member is made of elastic material that combines flexibility and stability. This composite material property allows the member to both conform to position deviations (improving precision) and maintain reliable contact forces (ensuring stability), resolving the contradiction between precision and reliability.
2Manufacturing precision
If the camera position is strictly fixed, then alignment is maintained, but the structure becomes complex
Solution Approach 1:
The elastic positioning member automatically adjusts to camera position deviations through its elastic deformation. It self-compensates for misalignment without requiring external adjustment mechanisms or complex positioning systems, thereby maintaining alignment precision while keeping the structure simple.
Solution Approach 2:
The positioning member transitions from a static rigid structure to a dynamic elastic structure that can adapt its shape. This dynamic capability allows the member to automatically adjust to position variations, maintaining alignment precision without adding structural complexity.
3Reliability
If the positioning member is made rigid, then structural stability is high, but it cannot compensate for position deviations
Solution Approach 1:
The patent changes the mechanical parameter of the positioning member from rigidity to elasticity. This allows the member to maintain structural stability through elastic restoring forces while simultaneously gaining the adaptability to deform and compensate for position deviations in the camera assembly.
Solution Approach 2:
The elastic positioning member acts as a cushion that anticipates and absorbs position deviations before they cause misalignment. The elastic deformation provides a buffer zone that compensates for manufacturing tolerances and assembly variations, maintaining both stability and adaptability.
