Solution Overview
Problem
Conventional switching devices face challenges in meeting both front and side operation requirements due to their large volume and mechanical complexity, leading to instability and increased wear, which limits their application in space-constrained scenarios.
Innovation Solution
An operating apparatus with a bracket, side operating unit, and front operating unit is designed, incorporating conical teeth and a connecting rod energy storage assembly, allowing for synchronized front and side operations without intermediate gears, reducing volume and improving reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two separate operating mechanisms are used for front and side operations, then both operation modes can be achieved, but the device volume becomes large
Solution Approach 1:
The patent combines front and side operating mechanisms into a single integrated operating apparatus. The driving block with conical teeth serves as a common transmission element that can be actuated from either the front or side, eliminating the need for two separate mechanisms and reducing overall device volume.
Solution Approach 2:
The operating apparatus is designed with universal functionality to accept operation inputs from multiple directions (front and side). The conical teeth mechanism can be driven by either a front operating handle or a side operating handle, making the same mechanism serve multiple operational purposes.
2Ease of operation
If intermediate gears are used to transmit motion between front and side operations, then motion transmission can be achieved, but the device complexity increases
Solution Approach 1:
The patent removes the intermediate gears from the transmission path. Instead of using complex gear trains to transmit motion between front and side operations, the design directly couples the operating handles to the conical teeth mechanism, simplifying the overall mechanical structure.
Solution Approach 2:
The conical teeth on the driving block serve as an intermediary element that directly transmits motion from either operating direction without requiring additional intermediate components. This mediator approach simplifies the transmission mechanism compared to traditional gear-based solutions.
3Adaptability or versatility
If multiple separate components are used in the operating apparatus, then functional requirements can be met, but the reliability decreases due to more wear points
Solution Approach 1:
The patent merges multiple functional components into fewer integrated parts. The driving block incorporates the conical teeth directly, eliminating separate gear components. This reduction in component count decreases the number of potential failure points and wear interfaces, improving overall reliability.
4Volume of stationary object
If a compact design is implemented, then space utilization improves, but the operational smoothness and stability may deteriorate
Solution Approach 1:
The patent employs conical teeth with curved surfaces instead of traditional straight-toothed gears. This curved geometry allows for smoother engagement and more gradual force transmission, maintaining operational stability and smoothness while enabling a more compact overall design. The conical shape provides progressive contact that reduces shock loads and improves operational fluidity.
