Switch Mounting Mechanism for Compact Fluid Pressure Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing switch mounting mechanisms for fluid pressure devices, particularly compact fluid pressure cylinders with small operating strokes, face difficulties in mounting detection switches due to insufficient switch mounting groove length, leading to partial overlap and insertion issues.
Innovation Solution
A versatile switch mounting mechanism featuring a switch mounting groove with a groove opening wider than the switch housing chamber, a retainer screw that lifts the detection switch, and a switch holder with holding arms that undergo elastic deformation to accommodate the detection switch, allowing easy insertion and locking even in compact devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the switch mounting groove length is reduced to accommodate compact fluid pressure devices, then the device size is reduced, but the detection switch cannot be properly inserted and mounted
Solution Approach 1:
The switch holder is divided into multiple functional segments: elastic deformation portions at the ends that can compress independently, and a central detection switch receiving portion. This segmentation allows the switch holder to adapt to limited groove lengths by compressing the elastic portions rather than requiring the entire assembly to fit within the groove length constraint.
Solution Approach 2:
The elastic deformation portions change their physical state from rigid to flexible during installation. By applying compression force during insertion, these portions undergo elastic deformation, reducing their length temporarily to allow proper insertion of the detection switch and holder assembly into compact grooves, then return to their original shape to provide secure holding.
2Reliability
If the switch holder length is increased to ensure proper detection switch insertion, then the mounting reliability is improved, but the switch mounting groove cannot accommodate both the holder and detection switch in compact devices
Solution Approach 1:
The switch holder transitions from a static rigid structure to a dynamic structure with elastic deformation portions that can change length. During installation, these portions dynamically adjust their length by compressing, allowing the holder to fit into grooves shorter than its normal length, then maintain their deformed state or return to original shape to secure the detection switch reliably.
Solution Approach 2:
The elastic deformation portions are pre-designed with the capability to undergo compression before installation. This preliminary design feature enables the holder to be inserted into the groove first, followed by the detection switch, even when the groove length is insufficient to accommodate both components in their full extended states.
3Productivity
If the detection switch is positioned closer to the groove end to maximize groove utilization, then the groove space efficiency is improved, but the switch holder and detection switch overlap and cannot be inserted
Solution Approach 1:
The detection switch is nested within the switch holder's central receiving portion. The elastic deformation portions at the ends of the holder can compress to create temporary clearance, allowing the nested detection switch to be inserted along with the holder into the groove, even when the groove length is shorter than the sum of their individual lengths.
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 easy and reliable mounting of detection switches in both compact and regular-sized fluid pressure devices, overcoming the limitations of insufficient groove length and ensuring secure locking at the detection position.
Implementation Method 1
the switch holder undergoes the process of elastic deformation through a groove opening
Implementation Method 2
the retainer screw is tightened until the front end of the retainer screw is pressed in contact with the bottom of the switch mounting groove, thereby lifting up the detection switch
Implementation Method 3
The switch holder is pressed and held against groove walls of the switch mounting groove via the detection switch in the lifted state

AI summary
The present invention provides a switch mounting mechanism that can be adopted with ease in conjunction with a compact fluid pressure device. A space (31), to be used to absorb elastic deformation of a holding arm (33) occurring as a switch holder (24) is inserted through a groove opening (22A) of a switch mounting groove (22), is formed. A clearance (32) to be used as a buffer for the holding arm (33) is formed between the switch mounting groove (22) and a detection switch (21). As a result, the switch holder (24) can be inserted to assume the same position as the detection switch (21) inside the switch mounting groove (22).
