Solution Overview
Problem
Opto-mechanical systems face challenges with poor heat dissipation and shielding performance, leading to inefficiencies and increased replacement costs due to integrated component designs.
Innovation Solution
The opto-mechanical system is designed with independently disposed electronic control boards and a housing that includes a separating member forming an electromagnetic shielding structure, allowing for improved heat dissipation and electromagnetic interference reduction by separating the mainboard from other components and using metal members for shielding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the electronic control board and mainboard are integrated in a single housing, then the device complexity is reduced, but the heat dissipation performance deteriorates
Solution Approach 1:
The housing is divided into a first housing and a second housing that are separately disposed. The electronic control board is disposed in the first housing while the mainboard is disposed in the second housing. This segmentation allows each housing to be optimized for its specific function, with the first housing serving as an electromagnetic shielding structure and the second housing providing heat dissipation pathways, thereby resolving the contradiction between structural simplicity and thermal management.
2Ease of manufacture
If the electronic control board and mainboard are integrated, then manufacturing cost is reduced, but replacement efficiency deteriorates
Solution Approach 1:
The electronic control board and mainboard are disposed in separate housings, which are independently manufacturable. When replacement is needed, only the specific housing containing the defective component needs to be replaced rather than the entire integrated assembly. This segmentation maintains manufacturing cost efficiency while dramatically improving replacement efficiency and maintenance flexibility.
3Object-affected harmful factors
If metal members are used for electromagnetic shielding, then shielding performance is improved, but device weight increases
Solution Approach 1:
The shielding function is localized to only the first housing that contains the electronic control board, rather than shielding the entire integrated assembly. The first housing is designed as an electromagnetic shielding structure using metal members, while the second housing containing the mainboard does not require the same level of shielding. This segmented approach provides necessary electromagnetic protection where needed while minimizing overall device weight.
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
This design enhances heat dissipation performance, reduces replacement costs, and ensures normal operation by preventing electromagnetic interference, facilitating efficient and cost-effective upgrades and maintenance.
Implementation Method 1
both the separating member and the first board are designed to be formed by a metal member, which can form an electromagnetic shielding structure of the mainboard, to shield electromagnetic radiation outside the separating member and the first board from affecting the mainboard

AI summary
An opto-mechanical system is provided. The opto-mechanical system includes a light emission assembly, a light receiving assembly, a mainboard, a light scanning assembly, and an electronic control board. The mainboard is electrically connected to the light emission assembly and configured to control the light emission assembly to emit an emission light signal to the target object, and is electrically connected to the light receiving assembly and configured to control the light receiving assembly to receive an echo light signal reflected by a target object. The emission light signal is transmitted by the light scanning assembly to the target object, and the echo light signal is transmitted by the light scanning assembly to the light receiving assembly. The electronic control board is disposed independently of the mainboard and electrically connected to the mainboard, and is electrically connected to the light scanning assembly to control movements of the light scanning assembly.
