Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric module fixation systems face difficulties in securely attaching and removing electric modules from support frames, leading to challenges in ease of installation and removal.
Innovation Solution
An electric module with an engagement device featuring projections and resilient engagement elements that allow for easy insertion and removal by transitioning between expanded and retracted configurations, guided by abutment surfaces and protrusions for stable locking and unlocking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking device with a resilient locking element and actuating element is used, then the electric module can be locked and unlocked, but the device complexity increases and the assembly requires precise alignment
Solution Approach 1:
The patent extracts the complex resilient locking element and actuating element mechanism from the engagement device, replacing it with a simplified pressing element that directly presses the electric module against the support frame. This eliminates the need for intricate locking mechanisms while maintaining secure engagement through friction and geometric interlocking between the pressing element, electric module, and support frame.
2Reliability
If a resilient locking element with precise alignment requirements is used, then secure locking is achieved, but the ease of assembly deteriorates due to alignment sensitivity
Solution Approach 1:
The patent segments the engagement device into independent components: the pressing element, the electric module, and the support frame. Each component can be manufactured and assembled separately without requiring precise alignment between them. The pressing element is simply inserted into the receiving space and presses the electric module against the support frame, eliminating alignment sensitivity.
3Reliability
If a complex engagement device with multiple components is used, then locking functionality is achieved, but the number of parts increases
Solution Approach 1:
The patent merges the locking and securing functions into a single pressing element that performs both functions simultaneously. The pressing element combines the roles of a locking mechanism and a mounting component, eliminating the need for separate resilient locking elements, actuating elements, and other complex components. This unified approach maintains reliable locking functionality while significantly reducing the total number of parts.

AI summary
An electric device comprises a support frame, at least one electric module and an engagement device for locking the main body to the support frame when the electric module is received in the opening. The engagement device comprises a pair of projections which are spaced apart from each other so as to delimit with a portion of the support frame a seat which is intended to receive a connection portion of an engagement element. The engagement element comprises the connection portion which is formed to be received in the seat and is resiliently secured to a face of the electric module so as to be movable between an expanded configuration, in which the electric module is locked to the support frame, and a retracted configuration, in which the electric module can be removed from the support frame. The engagement element further comprises a pair of abutment surfaces which extend one opposite the other with respect to the engagement element so as to act as a guide.
