Camera Mount Decoupling Mounting and Demolding Directions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera modules for motor vehicles face challenges in simple and quick installation due to mismatched mounting and demolding directions, leading to complex and costly injection molding tool requirements, with visible parting lines and increased production complexity.
Innovation Solution
A camera module design featuring a camera mount with first and second fastening sections in different directions, allowing decoupling of mounting directions, incorporating metallic inserts with internal threads for screw connections, and optional clamp connections for quicker assembly, along with a positioning sleeve to protect the camera lens from lateral forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the camera module is mounted in a direction different from the demolding direction of the injection-molded component, then the mounting flexibility is improved, but the injection molding tool complexity increases and production cost rises
Solution Approach 1:
The fastening function is segmented into multiple directions by providing at least two fastening sections (first fastening section for first mounting direction, second fastening section for second mounting direction) on the camera mount. This allows the mounting direction to be independent from the demolding direction, resolving the contradiction between mounting flexibility and tool complexity.
2Ease of manufacture
If the mounting direction is changed to align with demolding direction, then the injection molding tool complexity is reduced, but the installation speed and assembly flexibility decrease
Solution Approach 1:
The camera mount is segmented with multiple fastening sections oriented in different directions, allowing the component to be mounted in various directions without changing the demolding direction. This maintains simple injection molding production while enabling fast installation in the desired mounting direction.
Solution Approach 2:
The fastening sections are arranged in different spatial directions (first mounting direction and second mounting direction) on the camera mount, adding directional dimensionality to the fastening capability. This allows independent optimization of mounting direction without being constrained by the demolding direction.
3Reliability
If multiple screw connections are used to secure the camera module, then the mounting security is improved, but the assembly time and complexity increase
Solution Approach 1:
The fastening system is segmented into multiple fastening sections that can be distributed across different mounting locations. This allows the camera module to be securely fastened with multiple connection points while enabling parallel assembly operations, reducing overall assembly time despite increased security requirements.
