Hydraulic module with a front, multiposition and disconnectable electrical enclosure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current heating devices face challenges with electrical box accessibility for maintenance, as they are either too large for constrained spaces or have fragile hinges that break under external stresses, hindering technician operation and requiring frequent replacements.
Innovation Solution
A hydraulic module with an electrical box fixed to the module body via a hinge system that allows rotation between functional and maintenance positions, disengaging under a predetermined torque to prevent breakage and provide additional flexibility, including a disengaged position for enhanced accessibility and robustness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the electrical box is made detachable or mobile to improve accessibility for maintenance, then ease of operation is improved, but device complexity increases and reliability decreases due to fragile hinges
Solution Approach 1:
The hinge system is designed with dynamic characteristics, allowing it to remain engaged during normal operation and only disengage when subjected to excessive torque. This enables the electrical box to be mobile for maintenance while protected during normal use, resolving the contradiction between accessibility and reliability
Solution Approach 2:
The hinge system's engagement state changes based on torque parameters. Under normal operating conditions, the hinge remains engaged providing structural integrity. When excessive force is applied, the torque exceeds the threshold and causes disengagement, preventing damage to the hinge while allowing the electrical box to be moved for maintenance
2Ease of operation
If the electrical box is positioned at the front for accessibility, then ease of operation is improved, but it hinders technician intervention when tilted forward
Solution Approach 1:
The hinge system allows the electrical box to be dynamically repositioned from the front functional position to a maintenance position that does not hinder technician intervention. The box can be tilted or rotated as needed while remaining connected, eliminating the harm of fixed positioning
3Ease of operation
If lateral clearance space is provided for the electrical box, then ease of operation is improved, but the product requires larger installation space
Solution Approach 1:
The electrical box is integrated into the module body through the hinge system, allowing it to be nested within the overall structure when not in use. The box can be positioned within the module's footprint while still providing accessibility, eliminating the need for additional lateral clearance space

AI summary
The invention relates to a hydraulic module (15) comprising an electrical box (35) movable in rotation relative to a module body (17) between: - a first position in which the electrical box (35) is arranged across a front access opening (56) to close the interior space (54), - a second position in which the electrical box (35) is out of the front access opening (56) so as to allow access to a rear face of the electrical box (35), in which the hinge system (60) is configured to disengage the electrical box (35) from the second position to a disengaged position when the hinge system (60) is subjected to a torque equal to or greater than a predetermined disengage torque value.
