Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas bolt heating apparatuses face safety risks due to excessively hot pre-heat chambers and reduced efficiency from limited air flow and cooling conduit usage, which can inhibit effective heating of bolt members.
Innovation Solution
A gas bolt heating apparatus design featuring a hollow heater body with circumferentially spaced cooling conduits and downwardly convergent air outlet passageways, allowing direct heating of the heating tube with a gas torch tip and improved air flow to enhance safety and efficiency, eliminating the need for a pre-heat chamber.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a pre-heat chamber is used to facilitate heating, then heating efficiency is improved, but the chamber becomes excessively hot and creates safety risks
Solution Approach 1:
The invention removes the pre-heat chamber entirely from the heating apparatus. Instead of using a chamber to indirectly heat the bolt, the torch tip directly heats the heating tube that contacts the bolt, eliminating the safety hazard of an excessively hot chamber while maintaining heating effectiveness.
Solution Approach 2:
The heating tube serves as an intermediary component between the torch tip and the bolt. The torch heats the heating tube, which then transfers heat to the bolt through thermal conduction, providing a safe and efficient heating mechanism without requiring a pre-heat chamber.
2Object-affected harmful factors
If cooling conduits are used to cool the chamber exterior, then user safety is improved, but heating efficiency of the chamber and heating tube is reduced
Solution Approach 1:
By removing the pre-heat chamber entirely, the invention eliminates the need for cooling conduits. The direct heating approach heats only the necessary components (heating tube and bolt) without creating excessive heat in a chamber that would require active cooling.
3Ease of operation
If downwardly convergent air outlet passageways are disposed within the central passageway, then flame direction is controlled, but air volume is limited and air flow is choked
Solution Approach 1:
The invention removes the restrictive downwardly convergent air outlet passageways from the central passageway. The torch tip is positioned to directly face the heating tube opening, allowing free air flow to the flame without chocking, while still achieving proper flame direction for heating.
4Device complexity
If the central passageway volume is limited, then device complexity is reduced, but air flow to feed the flame is insufficient
Solution Approach 1:
The invention simplifies the passageway structure by removing the complex downwardly convergent air outlet passageways. The torch is positioned to receive air flow directly through the central passageway opening, maintaining simple device structure while ensuring sufficient air volume reaches the flame for effective combustion.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution improves user safety by keeping the housing cool and allows for more effective heat distribution along the length of the heating tube, facilitating the loosening and tightening of bolts while reducing manufacturing costs compared to prior designs.
Implementation Method 1
a gas torch having a torch tip through which hot gas passes. The gas torch emits a flame
Implementation Method 2
The torch tip is configured to extend into the heating tube for directly heating the heating tube
Implementation Method 3
a plurality of circumferentially spaced-apart cooling conduits extending within and along the exterior wall of the housing
Implementation Method 4
a plurality of circumferentially spaced-apart, downwardly convergent air outlet passageways extending through the interior end of the insert. The downwardly convergent air outlet passageways are configured to direct air passing therethrough towards the torch tip for feeding and directing the flame
Implementation Method 5
The meshed threading of these components so heated longitudinally expands outwards, thereby facilitating the loosening and tightening of the stud head and/or stud
