Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing keyboards are often locked into specific key arrangements and functions, requiring users to purchase multiple devices for different applications, which is costly and wasteful.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If keyboards are locked into particular key arrangements and corresponding functions, then manufacturing precision and reliability are improved, but adaptability deteriorates
Solution Approach 1:
The keyboard is segmented into two independent parts: a fixed key body (base) and interchangeable key caps. The key body contains the transceiver circuit and maintains stable electrical connections, while the key cap contains the memory structure with ID data and can be freely replaced. This segmentation allows the stable base to provide reliability while the replaceable cap provides adaptability.
Solution Approach 2:
The key cap is designed as a universal component that can be used across different keyboard models within the same ecosystem. Each key cap contains a transceiver circuit and memory structure that can be read by any compatible keyboard base, allowing a single key cap to function on multiple different bases, thereby providing multi-functionality and adaptability.
2Adaptability or versatility
If users purchase multiple keyboard devices to accommodate different applications, then adaptability is improved, but cost and device complexity increase
Solution Approach 1:
The application-specific functionality is extracted from the entire keyboard device and concentrated into the interchangeable key caps. Instead of needing different keyboards for different applications, users only need to extract and swap the specific key caps that provide the desired functions. This reduces the number of devices from multiple complete keyboards to a single keyboard base with various key caps.
Solution Approach 2:
The functionality of different keyboard configurations is copied into the key caps through their memory structures that store ID data. Rather than physically creating multiple keyboard devices, the functional information is copied into reusable key caps that can be programmed with different key arrangements and functions, allowing virtual replication of multiple keyboard configurations without physical duplication.
3Adaptability or versatility
If key caps include transceiver circuit and memory structure, then adaptability and information storage are improved, but device complexity increases
Solution Approach 1:
The transceiver circuit and memory structure are merged into a single integrated key cap unit. Rather than being separate components that increase complexity, these elements are combined within the key cap itself, allowing the key cap to autonomously store its ID data and communicate with the keyboard base through its own transceiver circuit, thereby simplifying the overall system architecture.
Solution Approach 2:
The key cap is designed to be self-sufficient with its own transceiver circuit and memory structure, eliminating the need for complex external connection mechanisms. When a key cap is placed on a key body, it automatically performs self-identification by transmitting its stored ID data, and the system automatically configures itself without requiring complex manual setup or additional control circuits.

AI summary
A keyboard system comprises a housing and a key structure having a key body and key cap. The key body includes a transceiver circuit. The key cap includes a key cap transceiver and a memory structure storing a key cap ID data and/or a key function data corresponding to a key function. The transceiver circuit can poll the key cap memory via the key cap transceiver and retrieve the key cap ID data and/or the key function data. The keyboard system can determine a mapping of a location of the key cap on the keyboard by polling it and can generate and transmit a control signal to a host computing device communicatively coupled to the keyboard system based to the key cap ID and/or the key function data.
