Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If separate display and speaker components are used for audio and video outputs, then functional performance is achieved, but device size and weight increase
Solution Approach 1:
The patent combines separate display and speaker components into a single integrated device that produces both audio and video outputs through a unified structure, thereby reducing overall device weight while maintaining functional performance
Solution Approach 2:
The integrated device performs multiple functions (display and audio output) through a single multi-functional component structure, eliminating the need for separate dedicated components and reducing overall device mass
2Ease of manufacture
If separate display and speaker components are used for audio and video outputs, then functional performance is achieved, but device area increases
Solution Approach 1:
The patent merges separate display and speaker components into a single integrated structure that occupies less surface area, allowing both audio and video functions to be achieved within a compact footprint
Solution Approach 2:
The integrated device structure allows one component to be nested within or alongside another, enabling the display and speaker functions to share space and reduce the total area required
3Ease of manufacture
If separate signal processing units control display and speaker, then individual component performance is optimized, but synchronization reliability deteriorates
Solution Approach 1:
The patent combines separate signal processing units into a single unified control system that simultaneously manages both display and speaker outputs, ensuring synchronized operation while maintaining component performance optimization
4Ease of manufacture
If electroluminescent components are randomly distributed in a matrix, then material fabrication is simplified, but light luminance and sound level decrease
Solution Approach 1:
The patent implements a structured arrangement where electroluminescent components are positioned at specific locations within the matrix rather than randomly distributed, creating local regions of high emission intensity that improve overall light luminance while maintaining fabrication simplicity
