Electrical Equipment Support Spacer Extraction Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical equipment supports make it difficult to both assemble and disassemble spacers, requiring significant effort and risk of damage due to the need to dismantle attached mechanisms and use tools to extract the spacer.
Innovation Solution
The support design allows the spacer to be held in position without exerting force on it, enabling easy engagement and extraction through a sliding movement within the plane of the rectangular opening, eliminating the need to dismantle attached mechanisms before extraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the spacer is held rigidly in the housing using latching teeth and hooking ribs, then the retention of the spacer is secure, but the disassembly becomes difficult and requires tools
Solution Approach 1:
The housing transitions from a static rigid retention structure to a dynamic system where the rear wall can move elastically. This allows the housing to adapt between a locked state (during assembly) and a released state (during disassembly), resolving the contradiction between secure retention and easy disassembly
Solution Approach 2:
The patent changes the mechanical parameter of the housing rear wall from rigid to elastic. This parameter change allows the rear wall to deform under force, enabling the spacer to be released from the latching teeth without requiring tool assistance, thus improving ease of operation while maintaining reliable retention during normal use
2Strength
If the latching teeth are positioned to securely hold the spacer, then the spacer retention is strong, but the risk of damage during disassembly increases
Solution Approach 1:
The elastic rear wall acts as an intermediary between the user's disassembly force and the latching teeth. Instead of directly forcing the spacer against the rigid latching teeth (which causes damage), the elastic rear wall absorbs and distributes the force, mediating the interaction to prevent harmful effects while still enabling spacer release
3Reliability
If the housing structure is complex with multiple latching mechanisms, then the spacer retention is reliable, but the device complexity increases
Solution Approach 1:
The patent extracts the complex multi-component latching mechanism and replaces it with a single elastic rear wall element. This extracted solution maintains the reliable retention function through the elastic deformation mechanism while dramatically simplifying the housing structure, reducing the number of parts and assembly steps
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates quick and effortless spacer extraction, allowing simultaneous disassembly of all attached apparatus mechanisms without damaging the latching means, improving ease of use and reducing the risk of spacer damage.
Implementation Method 1
During this engagement, the tabs gradually bend, elastically, towards the bottom faces of the housings, until the spacer comes into abutment against the rear faces of the housings

AI summary
The support (100) has two housings (110, 120) opened towards each other and receive ends (12, 13) of a spacer (10) that is transversely connected in rectangular openings (105, 106). Each housing extends below a rear surface (108) of a frame (101) and comprises a front holding surface and a rear holding surface. The front holding surface is formed by the rear surface of the frame, and the rear holding surface is turned towards the front holding surface that is parallel to the rear holding surface.
