Solution Overview

Problem

The issue arises when customers with older digital video recorders (DVRs) pay the same for DVR services as those with newer models having higher storage capacities, leading to dissatisfaction due to limited recording capacity and the need for deleting content or sacrificing programming.

Innovation Solution

Implementing modular storage functionality in DVRs, allowing users to select and upgrade storage capacity based on their service fee, using various storage media like hard disk drives, CD ROM, DVD ROM, flash memory, and USB data cards, enabling fairer service provisioning by cable and satellite providers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If service providers lease DVR equipment to customers with different storage capacities, then newer customers receive superior equipment with larger storage, but customers pay the same amount for DVR services leading to dissatisfaction

Engineering Contradiction:
Improvestorage capacityVSAvoidservice fairness
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The patent segments the storage capacity into different service tiers (e.g., basic, standard, premium) with corresponding pricing. Customers can select their desired storage capacity level, and the system divides the total storage pool into allocatable units that are provisioned based on service subscriptions. This resolves the contradiction by allowing differentiated storage allocation while maintaining fair pricing structures.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system allows dynamic adjustment of storage capacity parameters based on service level agreements. Storage capacity is treated as a variable parameter that can be changed according to customer needs and payment levels. The patent implements mechanisms to allocate, de-allocate, and re-allocate storage space as customers upgrade or downgrade their services, ensuring fairness while accommodating different storage requirements.

Inventive Principle:
Principle #35Parameter changes

2Quantity of substance

If DVR hard disk drive capacity is increased to accommodate more programming, then users can record more content, but the cost of equipment and service increases

Engineering Contradiction:
Improvestorage capacityVSAvoidservice cost
Core Design Contradiction:
Quantity of substanceVSLoss of energy

Solution Approach 1:

The patent implements a shared storage pool that serves multiple customers simultaneously. Instead of each customer requiring dedicated high-capacity storage from the outset, the system creates a universal storage resource that is dynamically allocated based on individual service subscriptions. This allows the provider to offer large total storage capacity while customers pay only for their allocated portion, reducing individual service costs while maintaining high overall capacity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system implements dynamic storage allocation where customers can upgrade or downgrade their storage capacity based on changing needs and budget. Storage assignments are not fixed but can be adjusted in real-time based on service level changes. This dynamic approach allows customers to optimize their storage-to-cost ratio, paying only for the capacity they currently need while having the flexibility to expand when necessary.

Inventive Principle:
Principle #15Dynamics

3Quantity of substance

If DVR storage is filled to capacity, then maximum recording capability is achieved, but users must delete content or stop recording new shows

Engineering Contradiction:
Improvestorage capacityVSAvoidrecording flexibility
Core Design Contradiction:
Quantity of substanceVSAdaptability or versatility

Solution Approach 1:

The system performs preliminary actions by proactively managing storage allocation before capacity is fully exhausted. The patent implements mechanisms to monitor storage usage and automatically notify customers when approaching capacity limits. It also pre-allocates buffer space and implements automated content management policies (such as identifying removable content) before the storage is completely full, allowing seamless continuation of recording services without forcing users to manually delete content or stop recordings.

Inventive Principle:
Principle #10Preliminary action

AI summary

Modular storage functionality is provided for a digital video recorder (DVR), which may be configured in such a way as to limit a user's access to the whole storage capacity, and wherein a user may choose to increase or decrease the amount of accessible storage capacity of the internal storage medium.
