Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing memory systems, such as SSDs, face challenges in efficiently switching between different voltage levels during manufacturing and operation, requiring separate boards or jumpers for 3.3 V and 1.8 V, which complicates the handling of voltage changes.
Innovation Solution
The memory system incorporates a voltage automatic switching circuit and a level shift circuit that dynamically adjust signal voltages based on the input VIO 1.8 V signal, allowing the system to output either 1.8 V or 3.3 V, depending on the presence of the VIO 1.8 V signal, and convert logic signals accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate boards or jumpers are used for 3.3 V and 1.8 V voltage switching, then voltage level switching capability is achieved, but device complexity and manufacturing complexity increase
Solution Approach 1:
The patent merges the voltage switching function directly into the connector by integrating a voltage selection circuit and switching elements within the connector structure itself, eliminating the need for separate boards or jumpers. The connector includes switching elements that can selectively connect different voltage lines (3.3V or 1.8V) based on the state of control signals, thereby achieving voltage level switching capability while reducing device complexity.
Solution Approach 2:
The patent introduces a voltage selection circuit as an intermediary component within the connector that automatically detects the required voltage level and switches between 3.3V and 1.8V power supply lines. This intermediary mechanism handles the voltage switching task automatically through control signals, removing the need for manual jumper configuration or separate switching boards, thus reducing overall device complexity while maintaining adaptability.
2Adaptability or versatility
If separate boards or jumpers are used for voltage switching, then voltage level selection is possible, but ease of manufacture deteriorates
Solution Approach 1:
The voltage selection functionality is merged into the connector assembly itself, which is a single integrated component rather than multiple separate parts (boards or jumpers). This integration means that during manufacturing, only one component needs to be installed and configured, significantly simplifying the manufacturing process while maintaining the ability to select between different voltage levels through automated control signals.
Solution Approach 2:
The connector incorporates a voltage selection circuit that automatically determines the appropriate voltage level and configures the switching state without requiring external intervention or manual setup. The circuit responds to control signals and autonomously selects between 3.3V and 1.8V power supply lines, making the manufacturing process easier as no manual jumper configuration or separate board installation is needed.
3Ease of manufacture
If voltage switching is simplified without separate boards or jumpers, then ease of manufacture improves, but reliability may worsen due to integrated switching complexity
Solution Approach 1:
The voltage selection circuit acts as a reliable intermediary that automatically manages the switching between voltage levels based on control signals. By using dedicated switching elements and control logic within the connector, the system ensures reliable voltage selection without the potential connection issues or configuration errors that could arise from manual jumper installation or separate board connections. The automated control mechanism enhances reliability while maintaining ease of manufacture.
Solution Approach 2:
The patent replaces manual mechanical switching mechanisms (jumpers or separate boards that require physical configuration) with an automated electronic switching system controlled by electrical signals. This substitution eliminates the need for manual intervention and potential human error in voltage selection, thereby improving reliability while simplifying the manufacturing process as the switching function is automatically configured through control signals rather than physical assembly steps.
