Switchgear Rotary-Link Mechanism for Front and Side Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical switchgears often lack flexibility in operation modes, limiting their accessibility and usability in various mounting configurations, as they typically offer only a front rotary operation mode with no side access or require additional accessories for operation.
Innovation Solution
The electrical switchgear design incorporates a housing with perpendicular rotary elements and a link element that allows for both front and side rotary operations, as well as a toggle switch mode, without the need for handle bars or knobs, utilizing bevel gears and elastic elements for efficient contact movement and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional electrical switchgears use only a front rotary operation mode, then the structure is simple, but the accessibility and usability in various mounting configurations are limited
Solution Approach 1:
The switchgear is designed with two rotary elements having perpendicular rotation axes, enabling the device to perform multiple operation modes (front rotary operation and side rotary operation) through a single integrated structure. This multi-functional design allows the switchgear to be operated from different directions without requiring separate devices or accessories.
Solution Approach 2:
The invention introduces a second rotation axis perpendicular to the first, adding a dimensional aspect to the operation mechanism. The second rotary element enables side rotary operation by rotating around an axis perpendicular to the front operation axis, effectively utilizing three-dimensional space to achieve multiple operation modes within the same device footprint.
2Ease of operation
If side rotary operation mode is added to enable mounting in inaccessible places, then accessibility is improved, but the device complexity increases
Solution Approach 1:
A link element is introduced as an intermediary component to connect the first and second rotary elements. This link element translates the rotational movement of the second rotary element (operated from the side) into rotational movement of the first rotary element (which actuates the contacts), enabling side operation without requiring direct mechanical connection between the side operator and the contact mechanism.
Solution Approach 2:
The invention merges the front rotary operation mechanism and the side rotary operation mechanism into a single integrated system. Both rotary elements share common components such as the link element and the contact actuation mechanism, allowing the device to achieve multiple operation modes while minimizing the increase in overall complexity.
3Adaptability or versatility
If multiple operation modes are implemented, then versatility is improved, but the installation space requirement increases
Solution Approach 1:
The second rotary element is positioned such that it can be integrated within or adjacent to the housing structure, with its rotation axis perpendicular to the first rotary element. The link element connects the two rotary elements in a compact arrangement, allowing the multi-functional mechanism to be nested within the same installation footprint rather than requiring additional space for separate operation mechanisms.
