Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wired charging is used for portable apparatus, then charging function is provided, but operation convenience deteriorates due to cumbersome connection process
Solution Approach 1:
The patent replaces the mechanical wired charging system with a wireless charging system using electromagnetic induction. The multimedia apparatus includes a wireless charging unit that can wirelessly charge the portable apparatus when placed on its surface, eliminating the need for physical cable connections and improving charging convenience while reducing time loss.
Solution Approach 2:
The patent introduces a wireless charging unit as an intermediary between the power source and the portable apparatus. This charging unit enables energy transfer through electromagnetic fields without direct physical contact, serving as a mediator that resolves the contradiction between charging functionality and operational convenience.
2Measurement precision
If touch pad pixel synchronization is implemented, then input position accuracy is improved, but system complexity increases
Solution Approach 1:
The patent implements a feedback mechanism where the controller detects touch inputs on the touch pad, determines their positions, and synchronizes this information with the multimedia apparatus. The system continuously monitors and adjusts the coordination between touch pad coordinates and multimedia apparatus display positions, improving input accuracy through iterative feedback while managing complexity through automated control algorithms.
Solution Approach 2:
The touch pad serves multiple functions: it acts as both an input device for controlling the multimedia apparatus and a wireless charging surface. By integrating these functions, the system improves input position accuracy through a single unified interface while avoiding the complexity of separate systems for each function.
