Platform Conditioning System Using Heated Air Ribs for Ice Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bridges and platforms are prone to freezing faster than adjacent land due to lack of earth-derived heat, leading to snow and ice accumulation, and conventional de-icing methods like road salt harm the environment and infrastructure.
Innovation Solution
A platform conditioning system featuring a network of ribs with fluid warming devices that circulate heated air to prevent ice formation, using a closed-loop system with flow inducing devices and heating elements, and insulated surfaces to maintain surface temperature above freezing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If road salt is applied to lower freezing temperature and melt ice, then ice removal effectiveness is improved, but environmental harm and material corrosion increase
Solution Approach 1:
The patent converts the harmful effect of cold temperatures into a beneficial controlled heating process. Instead of using road salt to lower freezing points, the system uses heated air circulation to actively raise temperatures above freezing, transforming the problem of cold into a controlled thermal management solution that eliminates salt-related environmental and corrosion issues
Solution Approach 2:
The patent introduces heated air as an intermediary substance to transfer thermal energy from heating devices to the bridge surface. This intermediary approach allows temperature control without direct contact with the bridge structure, eliminating the need for road salt application while achieving effective ice prevention through controlled heat transfer
2Reliability
If road salt is applied to prevent freezing, then freezing protection is improved, but corrosion of steel infrastructure increases
Solution Approach 1:
The system converts the harmful corrosive effect of road salt into a beneficial controlled heating process. By using heated air circulation, the system provides freezing protection without introducing chloride ions that cause corrosion, thereby extending the lifespan of steel infrastructure while maintaining effective ice prevention
Solution Approach 2:
The patent replaces the chemical mechanism of road salt (freezing point depression) with a thermal field mechanism (active heating). This substitution eliminates the chemical corrosion process while achieving the same protective function of preventing ice formation, thereby preserving infrastructure materials
3Object-affected harmful factors
If heated air circulation system is implemented, then environmental friendliness is improved, but device complexity increases
Solution Approach 1:
The patent makes the bridge structure itself serve multiple functions: the ribs that provide structural support also serve as conduits for heated air circulation. This multi-functionality reduces the need for separate dedicated components, thereby reducing overall system complexity while maintaining environmental friendliness
Solution Approach 2:
The bridge structure serves itself by using its own ribs as part of the heating system. The existing structural elements are repurposed to facilitate heat distribution, eliminating the need for entirely separate infrastructure and reducing system complexity while achieving green de-icing
4Reliability
If heated air is circulated through ribs, then ice prevention effectiveness is improved, but energy consumption increases
Solution Approach 1:
The patent applies heating locally through strategically positioned heating devices and targeted air circulation through specific ribs. This localized approach concentrates energy where it is most needed to prevent ice formation, rather than heating the entire bridge uniformly, thereby reducing overall energy consumption while maintaining effective ice prevention
