Mounting Rack With Circuit Integrating Conduction Into Molding Seat
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional face ID projector mounting racks are costly, bulky, and consume excessive power, with the laser diode remaining active even when the filtering lens is broken, leading to erroneous signal determination.
Innovation Solution
The mounting rack with circuit integrates the conduction circuit directly onto the molding seat of the projector rack, ensuring the laser diode is only activated when the filtering lens is intact, and features a compact design with reduced manufacturing complexity and cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the conduction circuit is connected from the circuit board to the mounting rack through a conductive wire, then the projector can be powered, but the manufacture time increases, manufacturing cost increases, and the device occupies more space
Solution Approach 1:
The patent merges the conduction circuit directly into the molding seat by integrating circuit traces into the mold during manufacturing. This eliminates the need for separate conductive wires and assembly steps, thereby reducing manufacturing time and cost while simplifying the overall structure.
Solution Approach 2:
The molding seat is designed to serve multiple functions: it provides structural support for the projector and simultaneously acts as the conduction circuit carrier. This multi-functionality reduces the number of components needed and simplifies the device structure.
2Volume of moving object
If the conduction circuit is connected through a conductive wire, then power can be supplied to the projector, but the projector becomes bulky and occupies more space
Solution Approach 1:
The circuit is merged into the molding seat structure itself, eliminating the need for external conductive wires. This integration significantly reduces the overall volume required for the projector assembly and removes unnecessary spatial occupation.
3Reliability
If the circuit board drives the laser diode even when the filtering lens is broken, then the system remains operational, but erroneous signal determination occurs
Solution Approach 1:
The integrated circuit design includes a detection mechanism that monitors the integrity of the filtering lens through the conduction path. When the lens is broken, the circuit detects the anomaly and automatically stops driving the laser diode, preventing erroneous signals while providing feedback about the system state.
Solution Approach 2:
The circuit is designed with protective features that prevent harmful operation before damage occurs. By monitoring the conduction path integrity, the system proactively prevents laser diode operation when the filtering lens is compromised, avoiding potential damage and ensuring accurate signal determination.
