Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If light sources are positioned near the display module to illuminate the display area, then illumination intensity is improved, but shadow areas are formed that reduce image quality
Solution Approach 1:
The patent transitions from a two-dimensional planar arrangement of light sources to a three-dimensional configuration where light sources are positioned at different heights and angles. Specifically, light sources are arranged in multiple layers with different z-coordinates, allowing light to reach the display area from multiple directions and eliminating shadow areas that would form with single-plane illumination.
Solution Approach 2:
Different regions of the display module are illuminated by light sources with locally optimized positions and orientations. Each light source is strategically positioned to illuminate specific areas of the display, with adjustment mechanisms allowing local optimization of illumination quality without affecting the entire display uniformly.
2Object-affected harmful factors
If multiple light sources are added to eliminate shadow areas, then image quality is improved, but device complexity increases
Solution Approach 1:
The light sources in the patent are designed to perform multiple functions simultaneously: they provide illumination, enable touch sensing through optical changes, and contribute to display visibility in various lighting conditions. This multi-functionality reduces the need for separate components, thereby managing device complexity despite using multiple light sources.
Solution Approach 2:
The patent combines illumination functions and touch sensing functions into a single integrated system using the same light sources and optical paths. The light sources serve dual purposes: illuminating the display and enabling capacitive touch detection, which reduces overall system complexity compared to having separate illumination and sensing systems.
3Volume of moving object
If a slim watch design is implemented with limited space, then portability is improved, but component arrangement becomes more difficult
Solution Approach 1:
The patent employs a nested arrangement where light sources, adjustment mechanisms, and display components are positioned in overlapping three-dimensional spaces. Components are arranged in layers with some elements positioned within the volume occupied by others, maximizing space utilization and achieving a slim profile while accommodating multiple functional elements.
Solution Approach 2:
The patent incorporates adjustable light sources with movement mechanisms that allow dynamic repositioning of components. This dynamic capability enables the system to adapt component positions based on operational requirements, maintaining a compact form factor while providing flexibility in component arrangement and optimization.
