Overhead Mirror Assembly for Rear View Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators of vehicles like front loading garbage trucks and dump trucks face visibility issues when lifting and rotating trash containers, as they cannot view the rear and above areas due to obstructed views from the cab, leading to inconvenient and uncomfortable actions during extreme weather conditions.
Innovation Solution
A rear view mirror assembly with multiple mirror units, including an overhead convex mirror unit, is mounted on the vehicle, allowing operators to see rear and above areas, featuring adjustable motorized mirror elements and heating elements for improved visibility in harsh conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the operator opens the window and sticks their head out to view the rear and above areas, then visibility of the lifting and rotation process is improved, but operator comfort and safety deteriorate due to exposure to extreme weather conditions
Solution Approach 1:
A rearview mirror assembly is introduced as an intermediary device that captures and transmits the image of the rear and above areas to the operator inside the cab. The mirror assembly includes a mirror positioned at an angle to reflect light from the rear area, allowing the operator to view the lifting and rotation process without exposing themselves to external weather conditions.
2Adaptability or versatility
If a traditional single mirror is used for rear view, then the structure is simple, but the field of view is insufficient to cover both rear and above areas
Solution Approach 1:
The mirror assembly is divided into multiple functional components: a support structure, a mirror mounting mechanism, and an adjustment system. This segmentation allows each component to be optimized independently while maintaining overall simplicity. The mirror itself is positioned at a specific angle to cover both rear and above areas, eliminating the need for multiple mirrors.
3Adaptability or versatility
If the mirror position is fixed, then the assembly is simple to manufacture, but the operator cannot adjust the viewing angle to different positions
Solution Approach 1:
The mirror mounting mechanism incorporates an adjustment feature that allows the mirror to be rotated or tilted to different angles. This dynamic capability enables the operator to customize the viewing angle according to their preferences and operational needs. The adjustment mechanism is designed to be simple, using basic mechanical elements like slots and pins, which maintains ease of manufacture while providing adaptability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances operator visibility and safety by providing a clear view of lifting and rotation processes without the need to exit the cab, improving comfort and reducing exposure to adverse weather.
Implementation Method 1
each mirror unit comprises a reflective mirror element
Implementation Method 2
at least one of the mirror units further comprises a heating element secured the rear surface of the mirror element
