Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The issue of camera eccentricity relative to the light-transmitting window in electronic devices, leading to reduced appearance fineness, is addressed by ensuring the center of the light-incident surface of the camera aligns with the center of the light-transmitting window using a positioning member that compensates for deviations and applies a rebound force to maintain alignment.
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 stabilize and correct deviations.
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 stability is poor causing center deviation
Solution Approach 1:
The positioning member is designed with asymmetric compressible capability, allowing it to dynamically adapt to camera position deviations. When the camera shifts, the positioning member compresses more on one side, generating a rebound force that pushes the camera back to the correct position, transforming a static limiting structure into a dynamic self-correcting system.
Solution Approach 2:
The positioning member utilizes changes in material compression parameters to achieve positioning correction. By designing different compressible capabilities at different locations, the system changes the mechanical parameter (compression) in response to position deviations, enabling automatic correction without requiring high-precision stable structures.
2Ease of manufacture
If the camera position is allowed to deviate, then assembly is easier, but the appearance fineness is reduced due to eccentricity
Solution Approach 1:
The positioning member performs self-service by automatically detecting and correcting camera position deviations during assembly. The asymmetric compressible structure enables the positioning member to self-adjust and generate corrective forces without external intervention, allowing easy assembly while maintaining high alignment precision.
Solution Approach 2:
The positioning member provides mechanical feedback through its asymmetric compression characteristics. When the camera deviates from the correct position, the positioning member compresses differently on each side, creating a feedback force that guides the camera back to the proper alignment, ensuring appearance fineness without complicating assembly.
3Manufacturing precision
If a rigid positioning structure is used, then positioning is precise, but it cannot compensate for position deviations
Solution Approach 1:
The positioning member transitions from a rigid static structure to a dynamic compliant structure with asymmetric compressible capabilities. This allows the system to maintain precise positioning while adapting to and compensating for manufacturing deviations through controlled compression and rebound forces.
Solution Approach 2:
The positioning member employs composite structural design combining regions of different compressible capabilities, integrating both rigid positioning functions and flexible compensation functions within a single component, achieving both precision and adaptability.
