Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sheet bending brakes face inefficiencies due to manual orientation and alignment challenges, accidental displacement of workpieces, cumbersome table structures, ergonomic design limitations, and lack of mechanisms to prevent cutoff pieces from falling, leading to reduced productivity and safety concerns.
Innovation Solution
A modular sheet bending brake with a foldable table, removable legs and wheels for easy transport, a coil holder with grippers to prevent material fall, ergonomic measuring features, and a built-in slicer assembly to manage cutoff pieces, enhancing alignment precision and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual positioning and alignment operations are used for workpieces, then the brake can bend the workpiece along the desired line, but the operations take an inappropriately long time and alignment may be accidentally disrupted
Solution Approach 1:
The brake incorporates self-aligning features such as guide edges and positioning stops that automatically align the workpiece with the bending line, eliminating the need for manual measurement and adjustment by the operator. The workpiece itself interacts with these features to achieve proper alignment without external assistance.
Solution Approach 2:
Positioning stops and guide elements act as intermediaries between the workpiece and the bending mechanism, providing physical references that ensure accurate alignment. These intermediaries transfer the alignment function from the operator to the machine structure.
2Ease of operation
If a cradling device with legs is positioned adjacent to the bending brake to support the coil, then the coil can be unrolled, but the device may be knocked over or the coil may slip off, requiring recurrent resetting that slows the process
Solution Approach 1:
The coil support function is merged with the bending brake structure itself. The brake incorporates integrated coil holders or support elements that are part of the main frame, eliminating the need for separate cradling devices with legs that can be knocked over. The support structure becomes an inherent part of the bending operation station.
3Quantity of substance
If workpieces are aggregated on the ground after cutting, then they can be stored, but they become damaged or soiled
Solution Approach 1:
Instead of storing workpieces on the ground (horizontal plane), the brake includes an elevated table or platform structure that raises the storage surface to a higher dimension. This dimensional change removes workpieces from the harmful ground environment while providing adequate storage capacity.
4Measurement precision
If rulers are mounted transversely to the longitudinal axis of the machine for marking workpieces, then measurements can be taken, but the rulers interfere with the craftsman's movement along the workpiece
Solution Approach 1:
The rulers are made movable or retractable rather than fixed in a transverse position. They can be extended when needed for measurement and retracted or swung aside when the operator needs to move along the workpiece, providing both measurement capability and operator mobility.

AI summary
A bending brake for sheet material includes frames; an upper jaw and a lower jaw that cooperate to hold the sheet material a bending surface pivotally connected to the lower jaw to bend the sheet material against an anvil of the upper jaw; an interlocking unit connected to the frame and having a cam surface which has having a locking position; and an elongated pipe assembly for rotation by a user. The elongated body bears against the cam surface and rests in the locking position to clamp the sheet material with reduced freedom of play.
