Separable Oscillating Frame Housing with Self-Centering Lock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing support housings for electronic components in vehicles have permanently installed oscillating frames, requiring complex and costly assembly before delivery, with cumbersome closure elements that can lead to leakage and logistical challenges, including inability to make changes without delaying delivery.
Innovation Solution
Design of a support housing with separable oscillating frames that can be easily installed and tested outside the housing, featuring precise guide rails and a simple, tool-free closure system with locking elements that ensure a tight seal, allowing for early delivery and easy maintenance without returning damaged units to the factory.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If oscillating frames are permanently installed in the housing at the factory, then the housing provides complete protection and structural integrity, but the logistics become complex and delivery times are delayed
Solution Approach 1:
The housing system is divided into separate components: the housing itself and the oscillating frame with electronics. The oscillating frame can be produced independently and delivered separately, then inserted into the housing by the customer or installer. This segmentation allows parallel production and reduces delivery time while maintaining structural integrity through the insertion mechanism.
Solution Approach 2:
The oscillating frame with electronics can be produced, tested, and prepared in advance independently of the housing assembly. This preliminary action allows the electronics to be fully functional and tested before insertion, enabling early delivery of the operational component while the housing is prepared separately.
2Reliability
If complex assembly processes are used to ensure tight sealing, then the seal integrity is improved, but the ease of manufacture decreases
Solution Approach 1:
The closure element incorporates a self-centering mechanism that automatically aligns the cover with the housing opening upon insertion. The spring element provides automatic sealing pressure without requiring complex adjustment procedures. This self-service approach ensures reliable sealing while simplifying the assembly process to basic insertion and closing actions.
3Reliability
If traditional closure elements are used, then the cover can be secured, but the operation becomes awkward and leakage occurs due to excessive torque
Solution Approach 1:
The closure element features a self-centering mechanism that automatically positions the cover correctly when closed, eliminating the need for manual alignment. The spring-loaded sealing mechanism automatically applies the correct sealing pressure without requiring the user to apply excessive torque, preventing both leakage and operational difficulty.
Solution Approach 2:
The traditional mechanical tightening system is replaced with a spring-loaded automatic sealing mechanism. Instead of relying on user-applied torque to create the seal, the spring element automatically provides the sealing force when the cover is closed, eliminating the problem of excessive torque application and making operation simple and intuitive.

AI summary
In a support housing (1), at least one end cover (7) is attached to the housing frame (5) by means of a locking cylinder (19). The locking cylinder (19) is mounted in a guide sleeve (29) such that tilting the clamping lever (27) initially causes the locking cylinder (19) to rotate, followed by an axial retraction movement. The swing frame (3) is slidable on a guide rail (57) in the housing (1) and can be removed, and locked in the housing by means of a locking shaft (67).
