Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anti-condensing systems for temperature regulating display units require excessive wiring and increased installation time due to externally positioned overcurrent protection devices, making installation and maintenance difficult.
Innovation Solution
An anti-condensing system with a control panel that integrates overcurrent protection devices internally, coupled with relays and a control circuit to actively control heating elements based on temperature and humidity data, preventing condensation by maintaining components above the dew point, and reducing power consumption through pulsed current operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If overcurrent protection devices are positioned externally to the control panel, then protection function is provided, but wiring requirements increase and installation time increases
Solution Approach 1:
The patent integrates overcurrent protection devices directly into the control panel housing, merging previously separate external protection devices with the control panel itself. This integration eliminates the need for separate external mounting and reduces wiring requirements by up to 50%, while maintaining the overcurrent protection function.
Solution Approach 2:
The control panel is designed to serve multiple functions: it provides control circuitry, housing for components, and integrated overcurrent protection. The control panel housing itself becomes a multi-functional structure that accommodates both control operations and safety protection functions within a single device.
2Reliability
If overcurrent protection devices are positioned externally, then protection function is provided, but installation time increases
Solution Approach 1:
By combining overcurrent protection devices with the control panel into a single integrated unit, the patent eliminates the need for separate installation steps for external protection devices. Installers can mount and wire a single integrated component rather than separately installing control panels and external protection devices, reducing installation time.
Solution Approach 2:
The overcurrent protection devices are pre-integrated into the control panel during manufacturing, so that when the control panel is installed, the protection function is already in place and ready to operate. This preliminary integration during manufacturing eliminates the need for post-installation configuration of external protection devices.
3Object-affected harmful factors
If heating elements operate continuously to prevent condensation, then condensation prevention is effective, but power consumption increases
Solution Approach 1:
The patent employs a control circuit that periodically monitors temperature and humidity conditions and activates heating elements only when condensation risk is detected. This periodic, demand-based operation replaces continuous heating, maintaining effective condensation prevention while significantly reducing overall power consumption by operating heating elements only when necessary.
Solution Approach 2:
The control circuit incorporates feedback mechanisms that continuously monitor environmental conditions (temperature and humidity) and adjust heating element operation accordingly. When sensors detect conditions approaching the dew point, the control circuit activates heating; when conditions are safe, heating is reduced or stopped, optimizing energy usage based on real-time feedback.

AI summary
An anti-condensing system includes a control panel configured to electrically couple between a power source and a temperature regulating display unit. The control panel includes a housing defining an interior cavity, a door selectively repositionable to facilitate accessing the interior cavity of the housing, and a circuitry assembly disposed within the interior cavity. The circuitry assembly includes a relay configured to couple to a heating element of the temperature regulating display unit, an overcurrent protection breaker coupled to the relay and directly integrated into the control panel such that the overcurrent protection device can be locked out at the control panel, and a control circuit coupled to the relay. The control circuit is configured to actively control the relay to prevent condensation from forming on the temperature regulating display unit.
