Sensor Fixation Device with Rotatable Mount Nut
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing sensor fixation devices for process system equipment are prone to nut loss during assembly due to limited mount space and high temperatures, leading to dropped nuts being lost.
Innovation Solution
A sensor fixation device with a body part having first and second openings for a mount bolt and nut, where the mount nut is rotatably retained with the body part, allowing it to be integrally secured and preventing loss, and is designed to be easily screwable regardless of the body's angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mount nut is retained separately from the body part, then the assembly structure is simple and easy to manufacture, but the nut may be lost during assembly due to dropping
Solution Approach 1:
The patent merges the mount nut with the body part by providing a through-hole in the body part that receives and retains the mount nut. This integration ensures the nut cannot be lost during assembly while maintaining structural simplicity. The nut is positioned in the through-hole and secured by the mount bolt passing through both the nut and the body part.
2Adaptability or versatility
If multiple independent members are used for mounting, then the mounting mechanism is flexible and adaptable, but the mount space required increases which is problematic in limited spaces
Solution Approach 1:
The patent combines multiple mounting functions into a single integrated structure. The body part with its through-hole and the mount bolt work together as a unified mounting mechanism, eliminating the need for separate retaining members and reducing the overall mount space required while maintaining adaptability.
3Ease of operation
If the mount nut is rotatably retained with the body part, then the nut can be easily screwed to the mount bolt regardless of body angle, but the retention mechanism becomes more complex
Solution Approach 1:
The patent makes the mount nut rotatable within the through-hole of the body part, allowing dynamic adjustment of the nut's orientation. This enables the nut to be screwed onto the mount bolt from various angles, improving ease of operation. The rotatability is achieved through the through-hole configuration that permits rotational movement while retaining the nut.

AI summary
[Task]To provide a sensor fixation device capable of preventing loss of mount nuts.[Solution]A mount body 130 of a sensor fixation device 100 in a mount state includes a first side wall 133a and a second side wall 133b which face with each other at the other end, which are perpendicular to a trap opening axis JT. The first side wall 133a includes a first mount nut retaining opening 133a1, and the second side wall 133b includes a second mount nut retaining opening 133b1. A mount nut 170 includes a nut spherical part 173 interposed between the first side wall 133a and the second side wall 133b, which has a diameter longer than the distance between the first side wall 133a and the second side wall 133b, and is configured to be engaged with a first side wall opening 133a1 and a second side wall opening 133b1. The mount nut 170 is retained integrally with the mount body 130, ensuring to prevent loss of only the mount nut 170 during the mount work.
