Fluid Measurement Device Cut-Out Corner Cable Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid measurement and control devices face challenges in space-saving cable routing, as cables are often bent at narrow radii, compromising mechanical stability and increasing space requirements.
Innovation Solution
The design incorporates a cut-out corner portion in the housing, forming a shoulder to accommodate the electric line connection, allowing the cable to protrude into the housing interior, reducing strain and space requirements, and providing protection through a lid that can be optionally sealed for moisture, dust, or mechanical protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the electric line connection is provided on the rear side of the housing, then the cable routing is simple, but the cable must be bent with a narrow radius which compromises mechanical stability and increases space requirements
Solution Approach 1:
The electric line connection is relocated from the rear side surface to the interior space of the housing, utilizing the third dimension (depth) rather than just the surface. The corner portion is cut out to create a shoulder that extends into the housing interior, allowing the cable connection point to be positioned inside the housing volume rather than on the external surface, thereby eliminating the need for sharp external cable bends.
2Area of stationary object
If the cable is bent at narrow radii to accommodate tight spaces, then the device can be arranged in narrow spaces, but the mechanical stability between device and cable is compromised
Solution Approach 1:
The housing structure is pre-configured with a cut-out corner portion and shoulder that extends into the housing interior before cable installation. This preliminary structural preparation provides a built-in cable management solution that guides the cable smoothly from the exterior into the housing interior, preventing sharp bends and maintaining cable mechanical stability while achieving compact device arrangement.
3Reliability
If the electric line connection is relocated into the housing interior via a cut-out corner, then cable mechanical stability is improved, but the housing structure becomes more complex
Solution Approach 1:
The housing is segmented into distinct functional zones: the main cuboid body and the cut-out corner portion with shoulder. This segmentation allows the cable connection function to be isolated in a specific structural feature (the shoulder) rather than integrating cable management throughout the entire housing, making the complexity localized and manageable while maintaining overall structural integrity.
4Length of stationary object
If the cable connection point is extended into the housing interior, then the effective length and space requirement are reduced, but the electric line connection requires additional structural features
Solution Approach 1:
The cut-out corner portion with shoulder serves multiple functions simultaneously: it reduces the effective length of the device by positioning the connection point inside the housing, provides structural support for the cable connection, creates a protected pathway for the cable, and maintains the overall cuboid aesthetic of the housing. This multi-functionality eliminates the need for separate external cable management components.
