Integrated Sensor-Lens Bayonet Mount for Larger Sensor Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera designs face challenges in aligning larger integrated sensors with lens assemblies due to limited packaging space, leading to interference and alignment issues.
Innovation Solution
A mounting structure, such as a bayonet, is used to connect the lens assembly with the integrated sensor without interfering with the sensor, allowing for alignment and installation without constraining the sensor or lens size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional mounting structures are used to connect lens and sensor, then alignment can be maintained, but the mounting structure interferes with larger integrated sensors and constrains component size
Solution Approach 1:
The patent removes the traditional mounting structure (flanges, fasteners, constraint mechanisms) from between the lens assembly and sensor. Instead, the sensor is directly mounted to the camera body, extracting the interfering mounting components while maintaining alignment through the sensor's direct connection to the body's optical axis.
Solution Approach 2:
The integrated sensor is positioned within the camera body such that it is located behind the lens assembly along the optical axis. The sensor footprint is nested within the lens assembly footprint, allowing the sensor to be larger than traditional sensors without requiring external mounting structures that would interfere with the optical path or constrain component sizes.
2Reliability
If larger integrated sensors are used to improve image quality, then sensor performance increases, but packaging space becomes limited and interference with lens assembly occurs
Solution Approach 1:
The patent transitions from a lateral mounting approach to an axial arrangement. The sensor is positioned behind the lens assembly along the optical axis, utilizing the depth dimension within the camera body rather than requiring lateral space. This allows larger sensor footprints to be accommodated within the limited packaging volume by exploiting the third dimension (depth along the optical axis).
3Productivity
If mounting structures constrain component sizes to fit within camera body, then packaging efficiency improves, but alignment accuracy and sensor performance deteriorate
Solution Approach 1:
The patent eliminates the mounting structure that previously constrained component sizes and interfered with alignment. The sensor is directly mounted to the camera body without intermediate mounting components, removing the source of alignment errors while allowing components to be sized according to performance requirements rather than packaging constraints.

AI summary
An image capture device with a bayonet, integrated sensor and lens assembly (ISLA), and fasteners. The bayonet includes an axis, mounting flange, fastener recesses and an inner flange. The axis extends through the bayonet. The mounting flange extends outward from the bayonet relative to the axis. Fastener recesses extending through the mounting flange. The inner flange extending inward from the bayonet towards the axis, wherein the inner flange is located between the mounting flange and the axis. The ISLA includes a forward end and internal lenses. The forward end that aligns with the inner flange to connect the ISLA to the bayonet. The internal lenses are located within the ISLA and aligned along an optical axis and the axis of the bayonet. The fasteners extend through the fastener recesses in the mounting flange to connect the bayonet to a first surface of the image capture device.
