Gaming Mouse Memory Expansion via Card Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The limited storage capacity of built-in memory in mice restricts the ability to adequately store complex button instruction sets required for gaming operations, especially for professional players, as it cannot accommodate the large data size of specific instruction sets used in gaming applications.
Innovation Solution
A mouse design that incorporates a portable memory card with large storage capacity, allowing the controller to save and read button instruction sets from both the built-in memory and the memory card, thereby expanding the memory capacity and enabling the storage of more complex operation settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the mouse uses only built-in memory to store button instruction sets, then the device structure remains simple and cost-effective, but the storage capacity is limited and cannot accommodate complex gaming instruction sets
Solution Approach 1:
The memory system is segmented into two independent parts: built-in memory for basic storage and an external memory card for expansion. This segmentation allows the system to achieve large storage capacity while maintaining simple device structure, as the memory card can be added or removed without affecting the core mouse structure.
Solution Approach 2:
The memory card interface is designed to be universal, allowing the same card to be used across different mouse models and even different computers. This multi-functionality enables the memory card to serve both as expansion storage for the mouse and as a portable storage medium that can be reused in various devices.
2Quantity of substance
If the mouse incorporates a memory card for expansion, then the storage capacity increases to accommodate large gaming instruction sets, but the device structure becomes more complex
Solution Approach 1:
The memory configuration is made dynamic and adjustable. Users can flexibly allocate instruction sets between built-in memory and memory card based on their needs, and the system dynamically manages data storage and retrieval from either medium. This dynamic approach allows optimization of storage usage without permanently increasing device complexity.
3Quantity of substance
If the built-in memory storage capacity is increased to accommodate all possible button instruction sets, then adequate storage is provided, but the cost of the mouse increases significantly
Solution Approach 1:
Instead of incorporating expensive large-capacity built-in memory, the system uses a memory card that can be mass-produced at low cost. The memory card acts as a disposable or replaceable component, allowing users to obtain large storage capacity without significantly increasing the base manufacturing cost of the mouse.
Solution Approach 2:
The memory card arrives pre-formatted and ready to use, with the ability to store complete instruction sets before being inserted into the mouse. This preliminary preparation eliminates the need for complex initialization procedures and allows the system to immediately utilize the expanded storage capacity upon insertion.

AI summary
A mouse with expandable memory capacity includes a button set with a plurality of buttons, a build-in memory, a card connector, and a controller. Therein, the card connector is for connecting with a memory card. The controller is connected to the button set, the build-in memory, and the card connector, wherein the controller is for controlling the operation of the build-in memory and for controlling the operation of the memory card so as to store a button instruction set. The controller further controls and uses the memory card to form an expansion memory for the build-in memory. The button instruction set records an operation instruction that is represented by combinations formed from one or more of the buttons. Therefore, the goal of expanding memory capacity of the mouse is achieved.
