Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing object tracking systems using optical transmitting units are limited by their unidirectional emission, resulting in reduced efficiency and coverage, particularly in areas not directly facing the device, leading to increased weight and cost due to higher-spec lenses required for precision.
Innovation Solution
An object tracking system with bidirectionally rotating optical transmitting units, driven by a power generation unit and controlled to adjust the optical path, allowing for reciprocal sweeping within a predetermined angle range, thereby increasing coverage and efficiency by emitting light pulses in previously blind spots.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a higher-spec lens is used for precise tracking, then tracking precision is improved, but device weight and cost increase
Solution Approach 1:
The patent applies dynamics by making the optical transmitting unit rotatable to change its emission direction dynamically. Instead of using a fixed high-spec lens, the system uses a standard lens that can be oriented toward different tracking areas through rotation, allowing precise tracking in multiple directions without increasing lens specifications or device weight.
2Measurement precision
If a higher-spec lens is used for precise tracking, then tracking precision is improved, but device cost increases
Solution Approach 1:
The system uses a rotatable optical transmitting unit with a standard lens instead of an expensive high-spec fixed lens. This dynamic orientation approach allows the same lens to serve multiple tracking zones, reducing the need for expensive high-performance optics while maintaining tracking precision across the entire field of view.
3Area of stationary object
If light is emitted to all areas including blind spots, then tracking coverage is improved, but device efficiency decreases due to self-obstruction
Solution Approach 1:
The optical transmitting unit rotates to emit light in different directions sequentially. By dynamically changing the emission direction, the system can cover areas that would otherwise be blind spots without the device obstructing the light path, as the rotation allows light to be emitted from different angular positions around the device.
4Device complexity
If unidirectional emission is used, then device simplicity is maintained, but tracking efficiency and coverage are reduced
Solution Approach 1:
The patent introduces a simple rotational mechanism to the optical transmitting unit, enabling it to change emission direction. This dynamic adjustment allows the system to cover multiple tracking areas and improve efficiency without adding significant complexity, as the rotation mechanism is straightforward and the control logic is relatively simple.
