Installable Wireless Module for Low-Cost Printer Connectivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Equipping media processing devices like printers with various communications technologies increases cost without benefiting all users, as each user may only require a subset of these technologies.
Innovation Solution
A user-installable wireless communications module for media processing devices, featuring a body with alignment features, an electrical interface, a communications controller, and an antenna support, which can be easily installed and removed without tools, allowing users to add WiFi connectivity only when needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If media processing devices are equipped with multiple communications technologies, then communication versatility is improved, but device cost increases
Solution Approach 1:
The communications module is segmented from the main device body, allowing it to be installed or removed independently. This enables the device to be manufactured without the module (reducing base cost) while still offering full communication capabilities when the module is installed by users who need them.
Solution Approach 2:
The communications module transitions from a static integrated component to a dynamic, user-configurable add-on. The module can be installed or removed based on individual user needs, making the system's communication capabilities adaptable rather than fixed.
2Adaptability or versatility
If media processing devices are equipped with multiple communications technologies, then communication versatility is improved, but device complexity increases
Solution Approach 1:
By segmenting the communications module as a separate, self-contained unit with its own housing and interface, the patent reduces the complexity of integrating multiple communication technologies into the main device. The module encapsulates all necessary components (antenna, circuit board, connector) in one package.
Solution Approach 2:
The communications module is designed as a universal interface that can provide multiple communication technologies (WiFi, Bluetooth, etc.) through a single standardized connection to the media processing device, reducing overall system complexity.
3Ease of manufacture
If users can selectively add communications modules, then cost efficiency is improved, but installation complexity increases
Solution Approach 1:
The patent incorporates preliminary design actions in the form of alignment features (protrusions and recesses) and pre-positioned connectors that guide the module into correct placement during installation. This preliminary structuring of the installation interface simplifies the user's task despite the added configurability option.
Solution Approach 2:
The alignment features and self-aligning connector design enable users to install the communications module themselves without requiring technical expertise or additional tools. The module's own structural features facilitate its proper installation.
