Solution Overview

Problem

Existing sawblade storage devices fail to provide efficient stacked storage capacity and protect sawblades from damage and rust, as they allow loose movement and do not inhibit lateral slippage effectively.

Innovation Solution

A stackable sawblade containment assembly comprising annular covers with protrusions and depressions forming a snap-fit relationship, an outer lip to prevent lateral slippage, and a flange depression for tagging, allowing for secure stacking and identification of sawblades.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If sawblades are stored in conventional storage devices, then storage is provided, but the blades slide loosely causing damage to teeth and inefficient storage capacity

Engineering Contradiction:
Improveprotection of sawblade teethVSAvoidstorage capacity efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The storage device is divided into multiple individual cavities, each capable of holding one sawblade securely. This segmentation allows each blade to be stored separately without contacting other blades, preventing tooth damage while maintaining efficient vertical stacking capability for high storage capacity.

Inventive Principle:
Principle #1Segmentation

2Stability of the object's composition

If conventional storage devices are used, then storage is provided, but lateral slippage of sawblades is not inhibited

Engineering Contradiction:
Improvepositional stability of sawbladeVSAvoidstructure complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The cavity structure incorporates localized features including vertical walls that contact the sawblade body and horizontal lips that contact the blade edges. These localized contact points provide precise positional control and inhibit lateral slippage without requiring complex overall structure, achieving stability with minimal added complexity.

Inventive Principle:
Principle #3Local quality

3Productivity

If stacked storage is implemented, then storage capacity is improved, but assembly and disassembly becomes difficult

Engineering Contradiction:
Improvestorage capacityVSAvoidassembly and disassembly convenience
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The stacked cavities are designed with complementary features that allow easy dynamic assembly and disassembly. Each cavity can be independently attached to adjacent cavities through simple interlocking mechanisms, enabling rapid stacking and unstacking operations while maintaining secure blade containment throughout the stack.

Inventive Principle:
Principle #15Dynamics

AI summary

A stackable sawblade containment assembly comprises a plurality of annular covers and an outer lip. The plurality of annular covers is defined by an outer perimeter, wherein each of the annular cover comprises a containment face and a base face, wherein at least one protrusion and at least one depression are coupled to the annular cover. The outer lip is disposed to extend along the outer perimeter and extending from the containment face. The at least one protrusion is disposed in general alignment with the at least one depression, whereby the at least one protrusion is configured to form a snap-fit relationship with the at least one depression. The containment face from one of the plurality of annular covers, and the base face from another one of the plurality of annular covers are detachably connected, forming an inner cavity and a stacked arrangement of annular covers.
