Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tablet computers face challenges in easily integrating ergonomic features, specialty input/output devices, and hardware-based data-entry systems due to complex and clunky implementation of add-on hardware enhancements.
Innovation Solution
A modular interface and attachment system with spaced interface channels built into the tablet or its case, allowing for easy attachment and detachment of accessories, including power conduits for auxiliary batteries, and various I/O devices, enabling a wide range of modular attachments without additional fitting kits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If add-on hardware enhancements are integrated into tablet computers, then functionality and capability are improved, but device complexity and implementation difficulty increase
Solution Approach 1:
The patent divides the tablet system into modular components: a base tablet unit and separate attachable accessories (keyboards, cases, scanners, batteries). Each accessory is an independent module that can be attached or detached as needed, allowing functionality to be segmented and reconfigured without permanently complicating the core device.
Solution Approach 2:
The patent creates universal attachment interfaces (such as magnetic adapters, snap-fit mechanisms, or standardized connectors) that can accommodate multiple different accessory types. A single interface design supports keyboards, protective cases, scanning devices, and power banks, enabling one system to serve multiple functions through interchangeable components rather than dedicated hardware for each function.
2Ease of operation
If multiple accessories are attached to tablet computer, then usability and productivity are enhanced, but attachment and configuration complexity increases
Solution Approach 1:
The patent incorporates pre-configured attachment interfaces and alignment features during tablet manufacturing. Magnetic arrays, guide rails, or standardized connector positions are built into the tablet housing before accessories are attached, so users simply need to snap or magnetically attach accessories rather than perform complex alignment or installation procedures.
Solution Approach 2:
The patent introduces intermediary attachment mechanisms (such as magnetic adapters, flexible cables, or universal connectors) that mediate between the tablet and diverse accessories. These intermediaries simplify the connection process by providing standardized interfaces that handle electrical, mechanical, and data connections in a single unified attachment action, rather than requiring separate connections for each accessory type.
3Adaptability or versatility
If specialized I/O devices and data-entry hardware are added, then enterprise capability is improved, but hardware integration complexity increases
Solution Approach 1:
The patent employs wireless communication technologies (Bluetooth, Wi-Fi, or near-field communication) that create virtual copies of hardware connection capabilities. Instead of physically integrating specialized I/O hardware into the tablet, the system uses wireless protocols to replicate the functionality of keyboards, scanners, and data-entry devices, allowing enterprise capabilities to be added through software-based wireless connections rather than complex hardware integration.

AI summary
A modular interface and attachment system for integration with, or use with, a tablet computer is disclosed. The system allows for the modular attachment of ergonomic features, specialty I/O devices, and specialty data entry hardware. Interface channels may be built into the rear surface of the tablet housing, while the accompanying accessories are provided with mating splines. The interface channels can also include electrical contacts to provide power to accessories that are mounted, or to facilitate the mounting of an auxiliary battery. Accessories that require a physical data or I/O interface with the tablet can be mounted at either end of the tablet at positions where data connectors are provided.
