Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a complex tool storage structure is used, then tool capacity and organization are improved, but the structure becomes prone to errors and harder to operate

Engineering Contradiction:
Improvetool capacityVSAvoidoperational simplicity
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The tool magazine is segmented into multiple independent storage rails that can be individually accessed. Each storage rail functions as an independent unit, allowing operators to access specific tools without manipulating the entire structure, thereby maintaining high tool capacity while simplifying operation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Storage rails are arranged vertically in multiple levels within the magazine housing. This vertical arrangement maximizes tool storage capacity in a compact footprint while allowing front-side access to all rails, eliminating the complexity of lateral or top-down access mechanisms.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If storage rails are extended from the front of the magazine housing, then accessibility to bending tools is improved, but the structural complexity increases

Engineering Contradiction:
Improvetool accessibilityVSAvoidstructural complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

Storage rails are designed to be movable rather than fixed, allowing them to be extended from the front of the magazine housing for tool access and retracted when not in use. This dynamic design improves accessibility while the simple linear movement mechanism avoids complex actuation systems.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The storage rails are designed to be manually extendable and retractable by operators without requiring powered actuators or complex mechanical systems. The rails self-support their own weight and the tools they carry during extension, eliminating the need for motors, hydraulics, or pneumatic systems.

Inventive Principle:
Principle #25Self-service

3Device complexity

If multiple bending tools are accommodated on a single storage rail, then the number of storage rails is reduced, but the mass to be moved increases

Engineering Contradiction:
Improvenumber of storage railsVSAvoidstorage rail mass
Core Design Contradiction:
Device complexityVSWeight of moving object

Solution Approach 1:

The tool storage system is divided into multiple lightweight storage rails rather than using fewer heavy rails. Each rail is designed to carry a manageable subset of tools, distributing the total weight across multiple independent components that can be moved separately with minimal effort.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

By arranging storage rails vertically in multiple levels, the system accommodates many bending tools across different heights rather than horizontally on fewer long rails. This vertical stacking reduces the length and mass of each individual rail while maintaining high overall tool capacity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

4Area of stationary object

If the tool magazine width is reduced, then the height can be increased for storage capacity, but accessibility may be compromised

Engineering Contradiction:
Improvefootprint areaVSAvoidtool accessibility
Core Design Contradiction:
Area of stationary objectVSEase of operation

Solution Approach 1:

The tool magazine utilizes vertical space by arranging storage rails in multiple levels from bottom to top. This vertical organization increases storage capacity without expanding the horizontal footprint, while all rails remain accessible from the front, maintaining ease of operation despite the compact width.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

All storage rails are designed to extend from the front of the magazine housing, ensuring that tools on any vertical level are equally accessible. This uniform front-side access mechanism maintains operational ease regardless of the magazine's narrow width or increased height.

Inventive Principle:
Principle #15Dynamics

AI summary

The invention relates to a tool magazine (26) for a bending machine (3), in particular for a press brake, wherein the tool magazine (26) has a plurality of storage rails (28), which are arranged in a magazine housing (27) and serve to hold bending tools (4), wherein the storage rails (28) are designed in such a way that a plurality of bending tools (4) can fit lined up one behind the other in the longitudinal extent (30) of the storage rails. The storage rails (28) can be pulled out from a front side (29) of the magazine housing (27) in the direction of the longitudinal extent (30) of the storage rails.
