Side-by-Side Holding Member for Guided Injection in Narrow Spaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices require a guide jig to insert a greasing pipe into a clutch housing, which cannot be applied when there is no space for fixing the guide jig, limiting their applicability.
Innovation Solution
A holding member that holds an injection portion and an imaging unit side by side, allowing the insertion portion to be inserted into a corresponding portion without a guide jig, utilizing a cylindrical shape with press-fitted semi-cylindrical portions and markings for alignment, enabling insertion in narrow spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a guide jig is used to insert the greasing pipe into the clutch housing, then the insertion direction can be guided, but the device cannot be applied when there is no space for fixing the guide jig
Solution Approach 1:
The patent combines the guiding function and the insertion portion into a single integrated holding member. The holding member has a body that guides the insertion direction and semi-cylindrical insertion portions that hold the injection portion and imaging unit, eliminating the need for a separate guide jig and enabling use in narrow spaces where a traditional guide jig cannot be fixed.
Solution Approach 2:
The holding member serves multiple functions simultaneously: it acts as a guide for insertion direction, a holder for the injection portion and imaging unit, and a positioning device with markings for angular alignment. This multi-functionality replaces the traditional guide jig system and enables operation in confined spaces.
2Ease of operation
If a traditional guide jig is used, then guidance can be provided, but the device structure becomes complex and requires additional components
Solution Approach 1:
The patent merges the guiding function, holding function, and positioning function into a single holding member structure. The body of the holding member provides guidance, while semi-cylindrical insertion portions provide holding capability, and markings provide positioning - all in one component rather than multiple separate parts.
Solution Approach 2:
The holding member is designed to perform multiple functions: guiding insertion direction through its body shape, holding the injection portion and imaging unit through semi-cylindrical insertion portions, and providing angular positioning through markings. This consolidates what would traditionally require multiple separate components into a single universal device.

AI summary
A holding member configured to hold an injection portion and an imaging unit of an insertion portion in a state in which the injection portion and the imaging unit are arranged side by side includes an injection-portion insertion portion configured such that the injection portion is press-fitted into the injection-portion insertion portion and an imaging-unit insertion portion configured such that the imaging unit is press-fitted into the imaging-unit insertion portion. The insertion portion is configured to be inserted toward a corresponding portion in a narrow space while being gripped by an operator. The injection portion has a cylindrical shape and is provided with a fluid substance injection port at a tip end portion. The imaging unit has a cylindrical shape and is configured to capture an image including the tip end portion of the injection portion and its surrounding environment.
