Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display modules in vehicles face errors in computing occupant proximity due to sensors being separate and distinct from the display, leading to inaccuracies in proximity sensing.
Innovation Solution
Integrating a sensor adjacent to or within the electronic display screen to detect radiation reflected from an object, improving proximity detection accuracy and reducing errors by minimizing the distance between the sensor and the object.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensors are positioned separately from the display, then the display module structure is simpler, but the proximity detection accuracy deteriorates due to increased distance between sensor and display surface
Solution Approach 1:
The sensor is integrated directly into the display module structure, positioned in close proximity to the display screen. This merging of the sensor with the display assembly eliminates the need for separate sensor mounting and reduces the distance between the sensor and the display surface, thereby improving proximity detection accuracy while maintaining structural simplicity
Solution Approach 2:
The display module structure is designed to serve multiple functions: it acts as both the display assembly and the sensor housing. The display module housing incorporates the sensor within its structure, allowing the same component to fulfill both display and proximity sensing functions, thus reducing overall device complexity
2Area of stationary object
If multiple separate sensors are used, then coverage area is sufficient, but the number of components and system complexity increases
Solution Approach 1:
The sensor is positioned to utilize the three-dimensional space around the display screen, detecting radiation from multiple angles and positions. By strategically placing the sensor within the display module housing, the system achieves comprehensive coverage of the display surface area without requiring multiple separate sensors, thus reducing component count while maintaining adequate detection coverage
