Multi-head Camera Transparent Cover Deformation Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-lens cameras face poor resistance to deformation of their transparent covers due to external impacts, which can lead to lens damage, and the existing lens adjustment mechanisms are cumbersome and inefficient.
Innovation Solution
The camera design incorporates a transparent cover with a flat and curved portion supported by a mechanism that reduces deformation, and a lens regulator with a movable first bracket and tooth slots for easier P-direction adjustment, allowing for improved resistance to external forces and efficient lens positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a transparent cover with a flat portion and curved portion is used to improve deformation resistance, then the resistance to deformation is improved, but the flat portion still undergoes large deformation under external impact
Solution Approach 1:
The patent applies local quality by providing different structural characteristics at different locations of the transparent cover. The curved portion has higher inherent deformation resistance due to its geometry, while the flat portion receives additional localized support from the supporting mechanism directly beneath it, creating non-uniform structural reinforcement where needed most.
Solution Approach 2:
The supporting mechanism acts as an intermediary element between the main casing assembly and the transparent cover. It transfers and distributes external forces away from the vulnerable flat portion of the transparent cover, preventing direct impact transmission that would cause large deformation and potential lens damage.
2Strength
If a supporting mechanism is added to support the transparent cover, then the deformation resistance is improved, but the device complexity increases
Solution Approach 1:
The supporting mechanism is merged with the existing main casing assembly structure. Rather than being a separate, independent support system, it is integrated into the housing design, sharing structural elements and mounting points with the main casing, thereby reducing overall system complexity while still providing the necessary support function.
Solution Approach 2:
The supporting mechanism serves multiple functions: it provides structural support to the transparent cover, acts as a mounting interface for the lens regulator, and serves as a force distribution element during impact events. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity.
3Ease of operation
If a lens regulator with movable bracket and tooth slots is used, then the ease of operation for lens adjustment is improved, but the device complexity increases
Solution Approach 1:
The patent replaces complex multi-component mechanical adjustment systems with a simplified tooth slot and meshing teeth mechanism. Instead of using traditional screw mechanisms, linkages, or motors for P-direction adjustment, the invention uses direct mechanical engagement between the movable bracket's meshing teeth and the tooth slots in the fixed bracket, providing easy manual operation with minimal parts.
4Productivity
If the movable bracket with meshing teeth is used for P-direction adjustment, then the productivity of lens adjustment is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The adjustment mechanism is segmented into discrete tooth slots and meshing teeth elements. This segmentation allows for modular manufacturing where each component can be produced separately with standard tolerances, then assembled together. The discrete nature of the teeth provides inherent positioning features that reduce the need for high-precision continuous surfaces, enabling faster adjustment while maintaining acceptable manufacturing tolerances.
