Solution Overview

Problem

Mechanical drive covers are difficult to access for maintenance and repair due to securement methods that complicate access, such as fasteners with exposed heads, making the process time-consuming and cumbersome.

Innovation Solution

A cover system with a separate mount and body that can be securely attached to the drive using fasteners or adhesives, featuring adaptable designs like protrusions and apertures for locking mechanisms, and spiral or bayonet-style securing methods to facilitate easy assembly and disassembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If covers are secured to drives using fasteners with exposed heads, then the covers are securely attached to the drive, but access to the mechanical drives for maintenance and repair becomes difficult and time-consuming

Engineering Contradiction:
Improvesecure attachmentVSAvoidaccess for maintenance
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The cover system is divided into separate components: a cover body and a mounting mechanism. The mounting mechanism includes an inner circumferential surface with features that engage with the drive, while the cover body remains separate. This segmentation allows the cover to be securely mounted while maintaining easy access, as the segmented design enables quick attachment and detachment without complex fastener operations.

Inventive Principle:
Principle #1Segmentation

2Strength

If covers are adequately secured to drives using fasteners, then the attachment is robust, but the process of securing and accessing the drives becomes even more difficult and time-consuming

Engineering Contradiction:
Improveattachment robustnessVSAvoidtime for servicing
Core Design Contradiction:
StrengthVSLoss of time

Solution Approach 1:

The mounting mechanism is extracted as a separate functional component from the cover body itself. The inner circumferential surface of the mounting mechanism includes engagement features that interface with the drive, while the cover body remains distinct. This extraction allows for a simplified attachment process that maintains robustness while reducing the time required for servicing, as the separate mounting mechanism can be quickly engaged or disengaged without manipulating complex fastener systems.

Inventive Principle:
Principle #2Taking out (Extraction)

3Reliability

If threaded fasteners with heads are used to secure covers, then the covers are firmly attached, but exposed surfaces are created that are not smooth and complicate access

Engineering Contradiction:
Improvefirm attachmentVSAvoidexposed surfaces
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The mounting mechanism is merged with the cover body to form an integrated assembly. The inner circumferential surface of the mounting mechanism, which provides the attachment function, is combined with the cover body structure. This merging eliminates the need for separate fasteners with exposed heads, as the integrated design provides firm attachment while maintaining a smooth, simplified exterior surface that does not complicate access to the drive.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A cover for use on a drive is adapted to be received by a feature on the drive. The cover includes a body and a mount. The mount is operably associated with the body. The mount is also adapted to cooperate with the feature on the drive to removably secure the cover to the drive. The mount and the body are separate components.
