Optical Device Terminals Multi-Dimensional Chassis Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a limitation on the miniaturization of terminals in optical devices, which restricts the increase in the number of terminals that can be extended from the sidewall, hindering the enhancement of the device's functionality.
Innovation Solution
The optical device incorporates a chassis with a first terminal extended from the bottom face and a second terminal from the side face, along with a projection portion on the bottom face that is higher than the distal end of the first terminal, allowing for increased terminal count by using a flexible printed circuit board for electrical connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If terminals are extended from the side wall of the chassis, then the optical device can be connected to external devices, but the number of terminals is limited due to miniaturization constraints
Solution Approach 1:
The patent extends terminals from multiple dimensions of the chassis: the first terminal extends from the bottom face while the second terminal extends from the side face. This multi-dimensional terminal arrangement allows increasing the number of terminals without being constrained by the limited space on a single face, effectively resolving the contradiction between terminal quantity and terminal size.
2Adaptability or versatility
If multiple terminals are extended from the chassis, then the optical device functionality is enhanced, but electrical shorts between terminals may occur
Solution Approach 1:
The patent introduces a projection portion as an intermediary structure between the first terminal and the second terminal. This projection portion physically separates the two terminals, preventing electrical shorts between them while allowing both terminals to extend from the chassis. This mediator structure enables enhanced functionality while maintaining electrical isolation and reliability.
3Area of stationary object
If terminals are miniaturized to fit more on the side wall, then space is saved, but the number of terminals cannot be increased
Solution Approach 1:
Instead of concentrating all terminals on the side wall area, the patent distributes terminals across multiple dimensions by extending the first terminal from the bottom face and the second terminal from the side face. This multi-dimensional distribution effectively increases the available area for terminals without requiring further miniaturization, resolving the contradiction between area utilization and terminal quantity.
