Modular Set Top Box Storage Assembly Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing set top boxes lack a storage facility, necessitating frequent replacements and operator visits for upgrading, which is inefficient for providers and users alike.
Innovation Solution
A modular assembly with a data storage device, such as a hard disk drive, and cooling means can be electrically and mechanically connected to existing set top boxes, allowing them to be adapted for data storage without requiring internal access or replacing components, enabling operation in both data processing and storage modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a set top box is provided with a data storage facility, then data storage capability is improved, but device complexity increases
Solution Approach 1:
The data storage facility is implemented as a separate, modular assembly that can be independently installed into the set top box. This segmentation allows the storage component to be added without redesigning the entire system, thereby improving data storage capability while minimizing the increase in overall device complexity.
Solution Approach 2:
The set top box is designed with a universal interface and recess structure that can accommodate the data storage assembly. This multi-functional design allows the same base unit to operate both without storage (original function) and with storage (enhanced function), resolving the contradiction between versatility and complexity.
2Adaptability or versatility
If set top boxes are upgraded by replacement, then data storage capability is improved, but loss of time increases
Solution Approach 1:
The data storage assembly is pre-configured as a complete, self-contained unit with all necessary connections and components. This preliminary preparation allows for rapid installation by simply inserting the pre-assembled unit into the recess, eliminating the need for complex on-site configuration and significantly reducing upgrading time.
Solution Approach 2:
The data storage assembly is designed to nest within the existing set top box structure, fitting into a dedicated recess. This nesting approach allows the storage component to be integrated without requiring external modifications or disassembly of the main unit, enabling quick upgrades while maintaining the original device's functionality.
3Ease of manufacture
If a recess is provided in the housing for assembly insertion, then ease of manufacture is improved, but device complexity increases
Solution Approach 1:
The housing is segmented to include a dedicated recess that specifically accommodates the data storage assembly. This segmentation simplifies the manufacturing process by allowing the recess to be molded or machined as a standard feature, making the modification to existing devices straightforward while maintaining a clean, integrated appearance.

AI summary
The invention relates to apparatus which can be used in first and second modes and to the manner in which the change in modes of operation can be achieved. In a first mode, the apparatus operates to receive data which is received typically from a television programme broadcast system and process the same and in the second mode the apparatus has the additional feature of a data storage device in which received data can be stored and be made available for subsequent retrieval. The data storage device can be provided as part of an assembly which can be mechanically and electrically connected to the apparatus housing and which allows the transfer of data between the assembly and the remainder of the apparatus. In one embodiment the assembly also includes cooling means which allow a cooling functionality to be provided to the apparatus.
