Interchangeable Keyboard Keys for Custom Shortcut Layouts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote control devices for media systems have limited flexibility in customizing shortcut buttons, which can lead to user frustration and increased production costs for manufacturers due to the need for mold modifications when changing button arrangements or adding/removing buttons.
Innovation Solution
A keyboard assembly with interchangeable keys that utilize a printed circuit board and key mat system, where each key has a unique identification mechanism, such as pins or conductive print, allowing users to customize key arrangements without requiring mold changes, and enabling easy replacement of keys with different functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If pre-labelled shortcut buttons are fixed in the remote control device, then manufacturing cost is reduced and production is simplified, but user flexibility and customization capability are limited
Solution Approach 1:
The button assembly is divided into separate, interchangeable button elements that can be individually removed and replaced. Each button is a discrete component that can be swapped without affecting the entire keyboard structure, enabling customization while maintaining simple manufacturing of the base unit.
Solution Approach 2:
The remote control device is designed with a universal button interface that can accommodate multiple different button configurations. The same base device can support various button arrangements and labels to serve different user preferences and streaming service configurations, making the device multi-functional.
2Ease of operation
If the number of shortcut buttons is increased to provide more streaming service options, then user convenience is improved, but the form factor becomes complicated and ergonomic design is compromised
Solution Approach 1:
The button configuration is made dynamic and adjustable rather than fixed. Users can change the number, position, and labeling of buttons according to their needs, allowing the device to adapt to different operational requirements without permanently increasing structural complexity.
Solution Approach 2:
Different regions or positions on the remote control can have different button configurations tailored to specific user needs. The interchangeable button system allows customization of local areas without redesigning the entire device, maintaining ergonomic form factor while improving convenience.
3Adaptability or versatility
If mold modifications are made to change button arrangement or add/remove buttons, then adaptability is improved, but production cost increases and production time is delayed
Solution Approach 1:
The button assembly is segmented into interchangeable components that can be modified independently of the main device mold. This allows button arrangement changes without requiring expensive and time-consuming modifications to the entire remote control mold, maintaining high production efficiency while improving adaptability.
Solution Approach 2:
The buttons are extracted as separate, removable elements from the fixed mold structure. This extraction allows the buttons to be changed, added, or removed without affecting the main device manufacturing process, eliminating the need for mold modifications and maintaining rapid production.
4Adaptability or versatility
If pre-labelled shortcut buttons are customized for each user, then user preference matching is improved, but manufacturing complexity and cost increase
Solution Approach 1:
Users are empowered to self-customize their own remote control devices by swapping buttons according to their preferences. This self-service approach eliminates the need for complex custom manufacturing processes for each user, maintaining simple standardized production while achieving personalized configurations.
Solution Approach 2:
Multiple pre-labelled button options are provided in advance, allowing users to select and assemble their preferred configuration without requiring custom manufacturing. The buttons are prepared beforehand with common streaming service labels, enabling quick user customization without increasing manufacturing complexity.

AI summary
There is a keyboard assembly for a handheld device, including a housing having a first section and a second section. The keyboard assembly has a plurality of slots formed on the first section. A printed circuit board (PCB) is disposed between the first and second sections. A key mat is sandwiched between the first section and the PCB, the key mat having a plurality of fixed keys and a plurality of interchangeable keys, each key protruding from the key's corresponding slot on the first section. Each interchangeable key has a unique identity, such that when each interchangeable key is replaced onto another slot on the first section, the interchangeable key's unique identity remains with the interchangeable key.
