Capacitor UPS Backup for Short Cable Power Interruptions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable television equipment experiences significant service interruptions due to short power disruptions caused by the removal of tap face plates in coaxial cable distribution networks, which are not effectively addressed by traditional battery-powered UPS systems, leading to prolonged service outages in advanced systems with CPU-embedded devices.
Innovation Solution
A specialized Uninterruptible Power Supply (UPS) system within the equipment, utilizing capacitors and/or batteries to provide partial power backup to critical components during short power interruptions, maintaining operational continuity and minimizing service disruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional battery-powered UPS systems are used, then power backup is provided, but service interruptions are not effectively addressed due to the nature of short power disruptions caused by tap face plate removal
Solution Approach 1:
The system performs preliminary actions by detecting the imminent power interruption event (tap face plate removal) before it occurs or as it begins, and preemptively switches to backup power sources (batteries or capacitors) to ensure continuous operation of critical components without service interruption
Solution Approach 2:
The power supply system is segmented into multiple independent power sources (main AC power, battery backup, and capacitor backup) that can operate independently or in combination, allowing the system to maintain critical functions during short interruptions while letting non-critical functions power down
2Ease of operation
If tap face plates are removed for maintenance, then access to coaxial cable connections is enabled, but short power interruptions occur causing service outages
Solution Approach 1:
The system provides beforehand cushioning by having backup power sources (batteries and capacitors) ready and connected in parallel with the main power supply, cushioning against the harmful effect of power interruption during tap face plate removal without affecting maintenance accessibility
3Adaptability or versatility
If CPU-embedded devices are used in advanced cable systems, then system functionality is enhanced, but service interruptions are prolonged due to recovery time requirements
Solution Approach 1:
The system ensures continuity of useful action by maintaining power to critical components (including CPU-embedded devices) during short interruptions through backup power sources, allowing these devices to remain operational or enter low-power states without full shutdown and recovery, thereby eliminating prolonged service interruptions

AI summary
A piece of equipment having a specialized Uninterruptible Power Supply (UPS). While there is external power supplied to the piece of equipment, a main power supply continuously supplies the entirety of the piece of equipment with a particular amount of power. The internal UPS supplies power to either the entirety of equipment or a proper subset of subcomponents within the piece of equipment when the piece of equipment is not supplied external power. The energy storage element of the internal UPS supplies power for a duration no longer than one minute and consists of one or more capacitors and not a battery. The amount of power supplied to subcomponents not in the proper subset of subcomponents is reduced while maintaining to supply the proper subset of subcomponents with the particular amount of power to conserve an amount of power remaining in the energy storage element.
