Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If multiple camera modules (ToF and RGB) are arranged in a compact space, then device miniaturization is achieved, but occlusion errors and heat management issues occur
Solution Approach 1:
The patent transitions from horizontal arrangement to vertical arrangement of camera modules along the optical axis direction. This dimensional change allows multiple modules (main camera, telephoto camera, ToF sensor) to be stacked vertically, reducing the horizontal footprint while maintaining functional separation and minimizing mutual occlusion, thus resolving the contradiction between miniaturization and performance reliability.
Solution Approach 2:
The patent implements a nested arrangement where camera modules are positioned at different depths along the optical axis, with each module nested within the overall compact structure. The main camera, telephoto camera, and ToF sensor are vertically stacked and integrated into a unified housing, achieving space-efficient nesting that maintains individual module functionality while minimizing overall device volume.
2Reliability
If camera modules are vertically arranged to minimize occlusion, then occlusion errors are reduced, but heat dissipation becomes more challenging
Solution Approach 1:
The patent extracts the heat dissipation function from the camera module arrangement by introducing dedicated heat dissipation structures and thermal management components. The vertical arrangement is maintained for occlusion reduction, while separate heat dissipation pathways are created through the housing structure, allowing thermal management without compromising the vertical stacking configuration.
Solution Approach 2:
The patent introduces heat dissipation structures as intermediary elements between the vertically arranged camera modules and the external environment. These intermediary thermal management components facilitate heat transfer from the compact vertical arrangement to the surrounding air, mediating between the space-efficient vertical configuration and the heat dissipation requirement.
3Productivity
If the camera device directly controls the object, then control efficiency is improved, but device complexity increases
Solution Approach 1:
The camera device is designed with multi-functional capability, serving both as an imaging device and as a control device. The control module integrated in the camera device can directly control the object based on captured images, eliminating the need for separate control systems and reducing overall system complexity while maintaining high control efficiency.
Solution Approach 2:
The patent merges the control function with the camera device by integrating a control module within the same housing. This combination consolidates imaging and control functions into a single integrated unit, reducing the number of separate components and interfaces while enabling direct control of the object based on visual feedback from the camera.
