Profile Rearview Mirror Housing for Low-Cost Length Customization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manufacturing process of central rearview mirrors for all-terrain vehicles requires complex CNC processing or new mould-opening for different lengths and sizes, resulting in high production costs.
Innovation Solution
A central rearview mirror design featuring a profile-shaped mirror housing with sliding chutes and removable end covers, allowing for adjustable length without the need for CNC processing or new mould-opening, using a solid straight bar with a unified cross-section and employing fasteners and buffer pads for secure assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If CNC processing or new mould-opening is used for different lengths and sizes, then manufacturing precision is improved, but production cost increases
Solution Approach 1:
The mirror housing is divided into a standard profile section (with unified cross-section) and variable end sections. The standard profile can be mass-produced through simple cutting, while only the end sections require customization, reducing overall manufacturing complexity and cost.
Solution Approach 2:
A universal profile with standardized cross-section is designed to serve multiple mirror housing length requirements. This standard profile can be cut to different lengths and combined with various end sections to create different mirror housing configurations, eliminating the need for separate CNC processing or mould-opening for each variant.
2Adaptability or versatility
If CNC processing or new mould-opening is used for different lengths and sizes, then product adaptability is improved, but device complexity increases
Solution Approach 1:
The mirror housing is segmented into a standard profile portion and customizable end portions. This allows the standard profile to be produced through simple cutting operations, while end portions can be adjusted for different lengths and sizes, achieving product adaptability without complex manufacturing processes.
Solution Approach 2:
The design allows for parameter changes (length and size) by modifying only the end sections of the mirror housing while keeping the standard profile unchanged. This enables flexible adaptation to different requirements through simple dimensional adjustments rather than complex manufacturing process changes.

AI summary
A central rearview mirror includes a profile-shaped mirror housing. The front of the mirror housing is provided with a first sliding chute, and a lens is slidably embedded in the first sliding chute. An end cover is removably installed at each of the two side ends of the mirror housing. The advantages of the central rearview mirror are as follows: The profile is adopted as the main body of the mirror housing, that is, the mirror housing is a solid straight bar with a certain cross-section shape so that each cross-section of the mirror housing is unified. When it is required to design central rearview mirrors of different lengths, it is only necessary to cut a large-length profile to obtain the mirror housing in the required length without tedious computer numerical control (CNC) processing or new mould-opening, thus reducing the production cost of the central rearview mirror.
