Wrench Width Adapter for Miniaturized Sensor Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pressure sensors with hexagon outer surfaces face limitations in miniaturization and configuration due to the need for a specific wrench width dimension that restricts the use of standard tightening tools, limiting their installation and flexibility.
Innovation Solution
A wrench width adapter with a base body having an inner recess with a regular polygon shape matching the sensor's wrench width dimension and an outer wall with a larger polygon shape to accommodate standard tools, allowing for adjustable configuration and integration of additional features like locking arrangements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the wrench width dimension of the sensor base body is reduced to enable miniaturization, then the sensor size is reduced, but standard tightening tools cannot be drawn over the plug part
Solution Approach 1:
The patent introduces a wrench width adapter as an intermediary component between the sensor base body and the tightening tool. The adapter has an inner wall with a first wrench width dimension that matches the reduced sensor hexagon, and an outer wall with a second wrench width dimension that accommodates standard tools. This mediator resolves the contradiction by allowing standard tools to operate on miniaturized sensors without direct contact.
Solution Approach 2:
The solution segments the torque transmission function into two separate components: the sensor base body maintains its minimized wrench width for compactness, while the adapter provides the interface for standard tools. This segmentation allows each component to be optimized independently - the sensor for miniaturization and the adapter for tool compatibility.
2Ease of operation
If the wrench width dimension is kept large to accommodate standard tools, then tool accessibility is maintained, but the sensor cannot be miniaturized and configuration freedom is limited
Solution Approach 1:
The adapter serves as a versatile intermediary that can be configured with different outer wall geometries to match various standard tools while maintaining compatibility with the sensor's minimized inner wall dimension. This provides configuration freedom for the sensor while ensuring broad tool accessibility through the adapter's customizable outer interface.
Solution Approach 2:
The adapter provides universal compatibility with standard tightening tools while enabling miniaturized sensor designs. The outer wall can be designed with different geometries to accommodate various tool types, making the adapter a multi-functional interface that bridges the gap between minimized sensor dimensions and standard tool requirements.
3Reliability
If additional features like locking arrangements are integrated, then security and anti-dismantling protection are improved, but device complexity increases
Solution Approach 1:
The patent merges the locking arrangement directly into the adapter structure, combining the torque transmission function with the security function in a single integrated component. The locking features are incorporated into the adapter's walls or surfaces, eliminating the need for separate locking mechanisms and reducing overall system complexity while maintaining enhanced security.
Solution Approach 2:
Additional security features such as locking arrangements or anti-dismantling protections are integrated locally into specific regions of the adapter where needed, rather than complicating the entire structure. This allows security enhancements to be added in targeted areas without unnecessarily increasing overall device complexity.

AI summary
A wrench width adapter for a component that is screwable into a threaded opening is provided, including a base body having a continuous inner recess, extending along a longitudinal axis, for receiving the screw-in component. An inner wall of the base body that delimits the inner recess, in a cross-sectional plane perpendicular to the longitudinal axis, has, at least in part, the shape of a regular polygon corresponding to a first wrench width dimension, and an outer wall of the base body has, at least in part, the shape of a regular polygon corresponding to a second wrench width dimension that is greater than the first wrench width dimension.
