Keyboard Module Integrated Protective Cover for Mobile Data Collectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data collectors combined with mobile electronic devices lack input interfaces, making it difficult for users to input or modify information, especially in adverse conditions such as wearing gloves or in wet weather, leading to usage inconvenience.
Innovation Solution
A mobile data collector design that integrates a keyboard module with a protective cover providing buffer and waterproof effects, allowing for input and modification of information, and can be easily adapted to other mobile devices by redesigning only the protective cover, reducing development time, cost, and labor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a touch screen is used for input on the mobile device, then the device can display and interact with information, but the user cannot input or modify information when wearing gloves or in wet weather
Solution Approach 1:
A physical keyboard is introduced as an intermediary input device between the user and the mobile device. The keyboard allows users to input information through mechanical key presses rather than touch, enabling operation while wearing gloves or in wet conditions where touch screens become unreliable.
2Adaptability or versatility
If a carrier is designed to hold the mobile device and data reader, then the components can be assembled, but no input interface is provided and the structure becomes complex
Solution Approach 1:
The protective cover is merged with the keyboard module to form an integrated assembly. This combination provides both protection and input functionality without requiring a separate complex carrier structure, as the keyboard-integrated cover serves multiple purposes simultaneously.
Solution Approach 2:
The protective cover is designed with multi-functionality, serving as both a protective element and a keyboard input device. This universal design eliminates the need for separate input interfaces and reduces overall structural complexity while enhancing adaptability.
3Ease of operation
If a protective cover is designed with integrated keyboard, then input functionality is added, but the development time and cost increase
Solution Approach 1:
The keyboard module is segmented as a separate, pre-designed unit that can be independently developed and tested. This modular approach allows the keyboard to be created once and then integrated into different protective covers, reducing overall development time and cost compared to custom-integrated solutions.
Solution Approach 2:
The keyboard module is designed as a reusable component that can be applied to multiple protective cover designs. By recovering and reusing the same keyboard module across different applications, development resources are optimized and time is reduced compared to designing custom keyboards for each product variant.

AI summary
A mobile data collector with a keyboard, used to be combined with a mobile electronic device, includes a protective cover, a data reader, and a keyboard module. The protective cover has a bottom plate and a surrounding frame. The surrounding frame is disposed along the perimeter of the bottom plate to form a first accommodation space and a second accommodation space located at one side of the first accommodation space. The mobile electronic device is disposed at the first accommodation space. The data reader is located at a side of the bottom plate opposite to the mobile electronic device and is electrically connected to the mobile electronic device. The keyboard module is disposed in the second accommodation space and electrically connected to the data reader. Thus, the mobile data collector has an input interface for inputting or modifying related information, which enhances usage convenience.
