Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in the disk drive market is to create a design that is both cost-effective and adaptable for low-cost mass production, while providing high data storage capacity, rapid access to data, and meeting decreasing size requirements, particularly for portable computing devices.
Innovation Solution
The integration of a hard disk drive assembly (HDA) with a non-volatile semiconductor memory (NVSM) and a printed circuit board assembly (PCBA) within a host computer, where the NVSM stores configuration data and a disk drive start program, enabling the host computer to control disk drive operations and simplify the manufacturing process by reducing the need for separate disk drive components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If disk drives are made smaller to meet portable device requirements, then device portability is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The patent combines the PCBA and HDA into a single integrated assembly, eliminating the need for separate components and reducing overall size while simplifying manufacturing. The integrated assembly includes the printed circuit board, hard disk drive, and associated components as one unified unit that can be directly installed in portable devices.
Solution Approach 2:
The integrated PCBA-HDA assembly serves multiple functions simultaneously: it provides data storage, processing, and control capabilities in a single component. This multi-functional design reduces the number of separate parts needed and simplifies the manufacturing process while maintaining compact dimensions suitable for portable devices.
2Adaptability or versatility
If separate PCBA and HDA components are used, then manufacturing flexibility is maintained, but device thickness and weight increase
Solution Approach 1:
The patent merges the PCBA and HDA into a single integrated assembly, reducing the overall weight and thickness of portable devices. By combining these components, the design eliminates redundant structural elements and connection interfaces, resulting in a lighter and thinner device while maintaining manufacturing flexibility through modular design principles.
3Adaptability or versatility
If configuration data is stored externally, then system adaptability is improved, but device complexity and size increase
Solution Approach 1:
The patent implements a nested structure where configuration data is stored within the integrated PCBA-HDA assembly itself, specifically in memory components embedded in the assembly. This nested storage approach eliminates the need for external configuration storage devices, reducing overall device complexity while maintaining system adaptability through programmable configuration options.
