Gas Supply Manifold Bent Rising Wall Structural Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing gas supply manifolds for gas-powered water heating apparatuses face challenges in reducing production costs and weight while preventing deformation and gas leakage, as thinning the cover member leads to warping and increased screwing complexity.
Innovation Solution
A gas supply manifold design featuring a bent rising wall portion around the gas supply flow path, bulging portions, and a loop-like sealing packing to enhance structural integrity and prevent deformation, along with a flange portion for attachment, reduces the need for additional screws and maintains gas tightness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of stationary object
If the thickness of the cover member is reduced to reduce weight and production cost, then weight and cost are reduced, but the cover member easily twists and causes deformation such as warp leading to gas leakage
Solution Approach 1:
The invention adds a third dimension by forming a bent rising wall portion that extends vertically from the cover member surface. This three-dimensional structure provides structural reinforcement against warping while maintaining thin overall thickness, thus preventing gas leakage without increasing weight or cost.
Solution Approach 2:
The bent rising wall portion is formed with a curved shape rather than a straight extension. This curvature provides structural strength to resist warping forces while using minimal material, preventing deformation of the gas supply flow path without compromising the thin design.
2Stability of the object's composition
If the number of screwed portions of the cover member to the main body is increased to suppress warp and deformation, then warp and deformation are suppressed, but the screwing procedure becomes complicated and the production cost increases
Solution Approach 1:
Instead of adding more screws in the same plane, the invention creates a bent rising wall portion that extends in the vertical dimension. This three-dimensional structure provides inherent warping resistance without requiring additional fastening points, thus maintaining simple screwing procedures while improving structural stability.
Solution Approach 2:
The invention replaces the mechanical reinforcement approach (adding more screws) with a structural geometry approach (bent rising wall). The curved wall portion itself provides the reinforcement needed to suppress warping, eliminating the need for additional screwed portions and simplifying the assembly process.
3Stability of the object's composition
If the number of screwed portions of the cover member to the main body is increased to suppress warp and deformation, then warp and deformation are suppressed, but the production cost increases
Solution Approach 1:
The invention combines the sealing function and the structural reinforcement function into a single integrated component - the bent rising wall portion. This wall portion simultaneously prevents gas leakage and resists warping, eliminating the need for separate reinforcement elements that would increase production cost.
Solution Approach 2:
By extending the cover member structure into the vertical dimension with the bent rising wall, the invention achieves structural reinforcement without adding material in the horizontal plane. This vertical extension provides warping resistance while maintaining cost-effectiveness through minimal material addition.

AI summary
A cover member of a gas supply manifold has a bent rising wall portion that is formed by bending a part of the cover member so as to rise in an opposite direction of a main body. The bent rising wall portion is in a form of a loop surrounding the entire circumference of a gas supply flow path and an area around the gas supply flow path. Such configuration increases the rigidity of the cover member and prevents large distortion of the cover member and leakage of gas from the gas supply flow path. As a result, the thickness of the cover member is reduced and the weight and the production cost of the gas supply manifold are also reduced.
