Rotatable Front Cover Lubricant Pump Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lubricant pumps require significant upper space for filling due to hinged covers, risk of cover loss, and complex, time-consuming adjustments for fill level sensors, leading to inefficient assembly and potential contamination.
Innovation Solution
A lubricant pump design with a rotatably mounted cover on the front side of the reservoir, allowing for reduced upper space usage and a simplified, angled cover that acts as a drip tray, along with a holding element for easy vertical alignment and attachment of the fill level sensor, reducing assembly complexity and space requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cover is fastened on the upper side of the reservoir with a hinge, then the cover can be easily opened and closed, but the space requirement in the upper area increases significantly
Solution Approach 1:
The cover is relocated from the upper side of the reservoir to the front side, changing the spatial dimension of attachment. This allows the cover to pivot forward instead of upward, dramatically reducing the vertical space requirement while maintaining ease of operation through the hinge mechanism
2Area of stationary object
If the cover is provided as a screw element instead of being hinged, then the space requirement is reduced, but the risk of cover loss increases
Solution Approach 1:
The cover is designed with a hinge mechanism that allows dynamic opening and closing motion. The hinge provides a reliable connection that prevents cover loss while enabling easy access, combining the benefits of both hinged and screwed covers
3Measurement precision
If the fill level sensor is arranged vertically in the bottom area of the reservoir, then correct measurement values are obtained, but complex adjustment and screwing is required
Solution Approach 1:
The fill level sensor is pre-mounted on the pump housing in a fixed position. The pump housing is designed with integrated sensor mounting features that automatically provide the correct vertical orientation when the pump is installed, eliminating the need for complex field adjustment and screwing operations
