Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protective covers for moving machine parts lack sufficient pretensioning force for uniform and resistance-free movability, often sagging and failing to achieve a seal between the machine parts and the environment, requiring a solution that ensures easy, reliable, and continuous sealing while being compact and cost-effective.
Innovation Solution
A protective cover with a frame element and a detachable or non-detachable protective cover element, equipped with a drive device and running rail, allowing for linear movement through the conversion of energy into a predetermined range of motion, ensuring uniform and resistance-free movement and sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional support frames and frame elements are used, then the protective cover structure is simple, but the protective cover lacks sufficient preload force for smooth movement and is prone to sagging and failure
Solution Approach 1:
The patent introduces a drive device with a motor that actively controls the movement of the protective cover along the guide rail, transforming a passive static support structure into an active dynamic system. The motor provides controlled driving force to overcome friction and ensure smooth, reliable movement without sagging, while the modular frame elements maintain structural simplicity.
Solution Approach 2:
The patent introduces a running gear as an intermediary component between the drive device and the protective cover. This running gear engages with the guide rail and transfers the driving force from the motor to the protective cover, enabling reliable movement while keeping the frame structure simple and modular.
2Object-affected harmful factors
If the protective cover is mounted on a guide without sufficient preload force, then the frame structure remains simple, but the protective cover is prone to failure and cannot seal properly
Solution Approach 1:
The motor-driven drive device dynamically adjusts and maintains the protective cover's position along the guide rail, ensuring continuous contact pressure for effective sealing. The active control system compensates for any sagging or positioning errors, guaranteeing proper sealing without requiring an overly complex frame structure.
Solution Approach 2:
The running gear acts as an intermediary that transfers the driving force and maintains proper contact between the protective cover and the guide rail. This ensures sufficient preload force for sealing effectiveness while keeping the overall frame structure simple and modular.
3Ease of operation
If conventional mounting without drive device is used, then manufacturing cost is low, but considerable force is required to move the protective cover
Solution Approach 1:
The running gear serves as a mechanical intermediary that engages with the guide rail's toothed profile, converting the motor's rotational force into linear movement. This gear engagement mechanism provides mechanical advantage, enabling easy movement of the protective cover with minimal input force from the motor.
Solution Approach 2:
The patent replaces manual or purely mechanical pushing force with an automated motor-driven system. The electric motor coupled with the running gear mechanism substitutes for human effort or external forcing, making operation effortless while adding controlled automation to the system.
4Reliability
If modular frame elements with drive device are implemented, then movement smoothness and reliability improve, but manufacturing cost increases
Solution Approach 1:
The frame is divided into modular frame elements that can be independently manufactured and assembled. This segmentation allows for standardized production of individual components, reducing overall manufacturing complexity and cost while enabling reliable assembly of the complete protective cover system with integrated drive devices.
Solution Approach 2:
The drive device and running gear assembly serves multiple functions: it provides driving force for movement, maintains proper positioning for sealing, and enables easy adjustment along the guide rail. This multi-functionality reduces the need for additional separate components, thereby controlling manufacturing costs while achieving reliable movement.
