Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The orientation of the display surface of a pressure gauge attached to a fluid pressure device cannot be changed, making it difficult to view in certain orientations.
Innovation Solution
A pressure gauge with a fitting structure that allows the attachment convex portion and adapter to change the relative position in the circumferential direction, enabling the display surface to be oriented in a direction that is easily visible to the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display surface is oriented in the axial direction of the screw member for simple attachment, then the attachment structure is simple, but the display surface cannot be changed to a direction that is easily visible to the user
Solution Approach 1:
The pressure gauge is divided into two attachable components: the gauge body and the adapter. The adapter is attached to the fluid pressure device via a screw member, while the gauge body can be attached to the adapter with the display surface oriented in a direction intersecting the attachment convex portion axis. This segmentation allows the display orientation to be independently adjusted without changing the attachment method.
Solution Approach 2:
The attachment structure is designed to allow relative rotational movement between the gauge body and the adapter. The display surface can be oriented in multiple directions (intersecting the axis of the attachment convex portion) by rotating the gauge body relative to the adapter, making the system dynamically adjustable rather than fixed in a single orientation.
2Adaptability or versatility
If the display surface is fixed in a specific orientation, then the attachment structure is simple, but the adaptability to different user needs and usage scenarios is reduced
Solution Approach 1:
The fitting structure between the gauge body and adapter allows rotational adjustment, enabling the display surface to be oriented in different directions (intersecting the axis of the attachment convex portion). This dynamic adjustability provides versatility for different user needs while maintaining a relatively simple attachment mechanism.
Solution Approach 2:
The adapter serves multiple functions: it provides the attachment interface to the fluid pressure device and simultaneously serves as a mounting platform that allows the gauge body to be oriented in multiple directions. This multi-functionality increases adaptability without proportionally increasing overall device complexity.

AI summary
A pressure gauge of a fluid pressure system includes a measurement unit, a case, a display unit, and an adapter. The adapter includes an attachment hole. The case includes an attachment convex portion which can be fitted into the attachment hole. The display unit includes a display surface oriented in a direction intersecting an axis of the attachment convex portion. The attachment convex portion and the attachment hole have a fitting structure capable of changing the relative position between the attachment convex portion and the adapter in the circumferential direction about the axis of the attachment convex portion.
