Deformable Housing Lip for Bore Component Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for installing components within bores, such as in fluid systems, often result in permanent alteration, making it difficult to remove or replace components without damage.
Innovation Solution
A device featuring a cup-like installation housing with a beveled annular lip that can be securely installed and removed using an automatic center punch, allowing for deformation of the lip to engage and disengage from the bore, enabling easy installation and removal without damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional methods (cementing, welding, screwing) are used to secure a component in place within a bore, then the component is securely fixed, but the component or bore is permanently altered, preventing easy removal or replacement
Solution Approach 1:
The housing lip is designed to be deformable, transitioning from a flexible state during installation to a locked state during operation. The lip can be radially expanded to engage the bore wall securely, then radially contracted to disengage for removal, enabling the system to dynamically change its mechanical state
Solution Approach 2:
The installation and removal process involves changing the radial dimension parameter of the housing lip. During installation, the lip is expanded radially to engage the bore; during removal, it is contracted radially to disengage, allowing the same component to achieve both secure fixation and easy removal
2Reliability
If conventional installation methods are used, then the component is securely installed, but removal requires damage to the component or bore
Solution Approach 1:
The housing lip is designed as a thin-walled, flexible structure that can elastically deform during installation and removal. This flexibility allows the lip to be radially expanded to engage the bore wall securely, then radially contracted to disengage without causing damage to either the housing or the bore
Solution Approach 2:
The system transitions from a static, permanent installation to a dynamic, reversible installation. The housing lip's ability to change its radial dimension allows it to engage and disengage from the bore through controlled deformation, eliminating the need for damaging removal methods
3Ease of repair
If a deformable lip structure is used for reversible installation, then the component can be removed without damage, but additional structural features (chamfers, grooves) are required
Solution Approach 1:
The housing lip is segmented into functional zones with different geometric features. The outer surface includes an annular groove that allows controlled flexing, while the inner surface has chamfers that guide the deformation process. This segmentation enables the lip to deform predictably and reversibly during installation and removal
4Reliability
If the housing lip is deformed outwardly to secure the device, then the device is firmly installed, but the same deformation method cannot be used for removal
Solution Approach 1:
The removal process uses the inverse of the installation process. During installation, the lip is deformed outwardly (radially expanded) to engage the bore wall. During removal, the lip is deformed inwardly (radially contracted) to disengage from the bore wall, using the opposite deformation direction to achieve the opposite functional state
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
Provides a secure and economical means for the installation and removal of system components within bores, allowing for maintenance and replacement without damaging the component or the bore.
Implementation Method 1
An automatic center punch is used to deform the housing lip outwardly to secure the device within an installation bore and inwardly to allow removal of the device from the installation bore
Implementation Method 2
For installation, a conical tip is used on the center punch to forcefully engage the inner chamfer of the housing lip and deform the lip outwardly
Implementation Method 3
for removal, a tip with a reverse conical surface is used with the center punch to forcefully engage the outer chamfer of the housing lip to deform the lip inwardly
Implementation Method 4
An annular groove is cut into the outer surface of the housing sidewall proximate to the housing lip to allow the housing sidewall to flex during installation and removal

AI summary
A method for removably securing a component within a bore having a shoulder, includes: forming a housing with a generally cylindrical wall with an open first axial end and a partially closed second axial end having an annular shoulder, and an annular lip section at the first end of the cylindrical housing wall, the lip section having a radially outwardly projecting and circumferentially extending annular ridge, an inner chamfer creating a frustoconical surface with a base toward the housing first axial end and an outer chamfer creating a frustonconical surface with a base toward the housing first axial end; and, inserting the housing into the bore, engaging the bore shoulder, engaging the inner chamfer of the housing lip section with a tool for applying axial force, the tool having a conical surface corresponding to and engageable with the housing inner chamfer, and applying axial force against the inner chamfer by means of the conical surface of the tool.
