Engineering Contradiction Analysis
1Ease of operation
If hardware logic devices such as CPLD, EC chip and control chip are used to achieve device control, then device control capability is improved, but system cost increases and operating system running efficiency decreases
Solution Approach 1:
The patent merges the functions of multiple hardware logic devices (CPLD, EC chip, control chip) into a single integrated hardware controller. This consolidation reduces the number of separate components interacting with the operating system, thereby decreasing system complexity and improving operating efficiency while maintaining comprehensive device control capabilities through the unified controller.
Solution Approach 2:
The hardware controller is designed as a universal component that can control multiple types of devices (storage devices, network devices, display devices, input devices) through different communication interfaces. This multi-functional approach replaces the need for multiple specialized hardware logic devices, reducing system complexity while maintaining broad device control capability.
2Ease of operation
If multiple hardware logic devices are used to achieve device control, then device control capability is improved, but the number of interactions between devices increases
Solution Approach 1:
The patent consolidates multiple hardware logic devices into a single integrated hardware controller that manages all device interactions centrally. This reduces the number of inter-device communication pathways from multiple separate device interactions to a single controller coordinating with the operating system, thereby simplifying the overall system architecture.
3Ease of operation
If additional hardware logic devices are added to enhance control functionality, then device control capability is improved, but system cost increases
Solution Approach 1:
The patent integrates the control functions of multiple separate hardware logic devices into a single hardware controller, reducing the total component count and thereby lowering manufacturing costs. This consolidation maintains comprehensive device control capability while eliminating the need to produce and assemble multiple separate hardware components.
Solution Approach 2:
The hardware controller is designed as a universal component that can control multiple types of devices (storage, network, display, input devices) through different communication interfaces. This multi-functional design replaces the need for multiple specialized hardware devices, reducing component diversity and manufacturing complexity while maintaining broad control capabilities.
