Adjustable Height Connection Chamber Head for Road Construction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing buried connection chamber devices experience instability and noise due to deformation of metal frames under vehicle traffic, leading to hollow gaps and reduced stability.
Innovation Solution
The connection chamber head employs wedges or screws integral with the shuttering frame to adjust its height, ensuring the buffer is flush with the ground, and uses a composite or plastic material chamber head with recesses for concrete sealing to stabilize the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the metal frame is adjusted to position the buffer flush with the roadway, then the buffer positioning is improved, but the metal frame deforms under vehicle traffic causing instability and noise
Solution Approach 1:
The patent changes the material parameter from metal to composite material for the frame, which fundamentally alters the mechanical properties to resist deformation under vehicle traffic while maintaining the ability to achieve flush buffer positioning through height adjustment members
Solution Approach 2:
The patent employs composite materials for the frame structure, combining materials with complementary properties to achieve both the precision positioning capability and the structural stability required to withstand vehicle traffic without deformation
2Adaptability or versatility
If the metal frame is used for height adjustment, then the height adjustment capability is achieved, but hollow gaps are created between the chamber and frame causing noise
Solution Approach 1:
The patent extracts the height adjustment function from the load-bearing frame structure, using dedicated height adjustment members that are separate from the main composite frame, allowing the frame to be filled with sound-absorbing material to eliminate noise from hollow gaps
Solution Approach 2:
The patent introduces sound-absorbing material as an intermediary substance filled in the hollow gaps between the chamber and the frame, which eliminates the noise problem while preserving the height adjustment capability provided by the separate adjustment members
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 provides enhanced stability and noise reduction by ensuring a secure, flush installation of the buffer, with concrete sealing ensuring long-term stability and reduced noise from vehicle traffic.
Implementation Method 1
the height adjustment members comprise wedges interposed between the shuttering frame and the bottom of the recessed part
Implementation Method 2
the height adjustment members comprise screws integral with the shuttering frame and which bear against the bottom of the recessed part
Implementation Method 3
recesses in which can be sealed, by concrete poured into the recessed portion of the chamber head pad receiving frame, tabs to seal the pad receiving frame in the chamber head
Implementation Method 4
The chamber head is made of composite or plastic material
