Adjustable Pipe Clamping for Precise Inner Diameter Expansion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pipe enlarging devices are cumbersome and costly due to the need for a long positioning member that requires precise alignment, making it difficult to adjust the position of the cone-shaped member relative to the pipe, and are not convenient for users to handle.
Innovation Solution
A pipe enlarging device with movable front, rear, left, and right clamps that form an adjustable clamping area, using resilient members and a front threaded rod to accommodate pipes of different sizes, along with a top threaded rod and cone-shaped member to enlarge the inner diameter of pipes, allowing for precise adjustment and alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a long positioning member with multiple holes is used to accommodate pipes of different sizes, then the device can handle various pipe diameters, but the device becomes costly and difficult to adjust
Solution Approach 1:
The positioning member is divided into multiple independent clamps (front clamp, rear clamp, left clamp, right clamp) that can move separately along the base. Each clamp can be independently adjusted to accommodate pipes of different sizes, replacing the single long positioning member with multiple smaller, adjustable components.
Solution Approach 2:
The clamps are designed to be movable rather than fixed, allowing dynamic adjustment of the clamping area. The front and rear clamps can slide along the base to change the distance between them, enabling the device to adapt to pipes of various diameters without requiring a long fixed positioning member.
2Adaptability or versatility
If the positioning member is made long to include multiple holes for different pipe sizes, then various pipe sizes can be accommodated, but the alignment precision becomes difficult to maintain
Solution Approach 1:
The clamps are designed with movable joints that allow precise adjustment of their positions. The front clamp can be positioned at different locations along the base by sliding it to the desired position and locking it in place, ensuring the clamping area is precisely aligned with the cone-shaped member center tip for each pipe size.
Solution Approach 2:
The clamps include self-aligning features where the clamping surfaces automatically adjust to match the pipe diameter. The resilient members in the clamps provide automatic adjustment to ensure proper alignment without requiring complex manual positioning procedures.
3Adaptability or versatility
If the positioning member is made long with multiple holes, then pipes of different sizes can be accommodated, but the device becomes cumbersome and inconvenient to operate
Solution Approach 1:
The adjustment mechanism is segmented into independent clamp units that can be adjusted separately. Each clamp has its own adjustment mechanism, allowing users to independently position the front, rear, left, and right clamps without affecting the other clamps, making the adjustment process simpler and more convenient.
Solution Approach 2:
The clamps are designed with smooth sliding mechanisms that allow easy movement along the base. The resilient members provide automatic return force, making it convenient for users to adjust the clamps by simply applying light force, and the clamps automatically return to their neutral positions when released.

AI summary
A pipe enlarging device includes a base, an operation unit and a clamping unit. The clamping unit is received in the base and includes movable front, rear, left and right clamps, multiple resilient members and a front threaded rod. The front, rear, left and right clamps are resiliently movable when the front threaded rod is rotated so as to form an adjustable clamping area between the front, rear, left and right clamps. The clamping area is used to clamp pipes of different sizes. The operation unit includes a top threaded rod with a cone-shaped member which is used to enlarge the inner diameter of the pipes.
