Greasing Pipe Insertion Jig With Tactile Position Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insertion amount grasping devices struggle to accurately establish a predetermined positional relationship between the distal end of a greasing pipe and the application portion, especially when the application portion is covered by a clutch housing, making it difficult for operators to confirm the correct alignment.
Innovation Solution
The insertion amount grasping device includes a first jig fixed to a clutch housing with a guide through-hole and an insertion portion with a protruding portion that causes friction when the predetermined positional relationship is established, allowing operators to manually confirm the alignment by feeling the friction, and optionally uses marking lines or protruding portions to assist in visual or tactile confirmation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the application portion is placed in an internal space surrounded by a clutch housing, then the greasing operation can be performed on internal components, but it becomes difficult for operators to grasp whether the predetermined positional relationship is established between the distal end part of the greasing pipe and the application portion
Solution Approach 1:
A protruding portion is introduced as an intermediary element between the insertion portion and the guide through-hole. This protruding portion transmits tactile feedback (friction sensation) to the operator's hand, serving as a mediator that makes the internal positional relationship detectable from the external operation side, thereby resolving the detection difficulty without changing the internal space configuration
Solution Approach 2:
The patent replaces visual inspection methods with tactile sensing. Instead of requiring operators to visually confirm the positional relationship (which is difficult when the application portion is enclosed), the system uses mechanical friction between the protruding portion and guide through-hole to generate tactile feedback, substituting the sensing modality from visual to tactile
2Adaptability or versatility
If multiple types of jigs are used for different vehicle configurations, then the greasing operation can be adapted to various application portions, but the device complexity and the number of required jigs increase
Solution Approach 1:
The guide through-hole is designed with a universal structure that can accommodate protruding portions of different dimensions. This allows a single guide through-hole design to work with multiple insertion portions for different vehicle configurations, eliminating the need for multiple specialized jigs while maintaining adaptability to various greasing requirements
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
Enables operators to accurately grasp the positional relationship between the greasing pipe and the application portion, facilitating efficient greasing operations without requiring visual inspection, thus improving operational efficiency and reducing the need for multiple jig types for different vehicle configurations.
Implementation Method 1
the first protruding portion is configured to be inserted into the guide through-hole and cause friction between the first protruding portion and the guide through-hole when a predetermined positional relationship is established

AI summary
An insertion amount grasping device includes: a first jig fixed to a fixation target in a state where the first jig is positioned against the fixation target, the first jig having a guide through-hole extending toward an application portion in a state where the first jig is fixed to the fixation target; an insertion portion inserted into the guide through-hole such that the insertion portion is introduced toward the application portion in a state where an operator grips the insertion portion; and a protruding portion as a protruding portion provided in the insertion portion, the protruding portion inserted into the guide through-hole and cause friction between the protruding portion and the guide through-hole when a predetermined positional relationship is established between a distal end part of the insertion portion and the application portion along with an introduction operation to introduce the insertion portion toward the application portion.
