Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If only linear or circular movement is used to shake bags, then the device structure is simple, but the emptying efficiency is insufficient and internal zones of the bag resist discharge
Solution Approach 1:
The patent applies dynamics by transforming the static or simple periodic motion into a dynamic complex motion trajectory. The shaker mechanism generates simultaneous linear and circular movements in multiple planes, creating a dynamic shaking pattern that adapts to different bag types and product characteristics, thereby improving emptying efficiency without requiring excessive structural complexity
Solution Approach 2:
The patent introduces another dimension by adding circular movement in addition to linear movement, and further extends to multiple planes. This multi-dimensional shaking approach ensures that all internal zones of the bag are addressed, preventing any region from resisting discharge, thus significantly improving productivity
2Productivity
If shaking frequency is increased to empty bags faster, then emptying speed improves, but energy consumption increases and product may be damaged
Solution Approach 1:
The patent applies parameter changes by allowing independent adjustment of shaking frequency, intensity, and amplitude. This enables optimization of the shaking parameters according to specific bag and product characteristics, achieving fast emptying speed while avoiding excessive energy consumption and product damage through precise parameter control
3Productivity
If shaking amplitude is increased to discharge adhesive products, then product discharge improves, but unnecessary energy is wasted and product may be thrown away from the collecting bin
Solution Approach 1:
The patent enables precise control of shaking amplitude as an independent parameter, allowing it to be adjusted according to product adhesion characteristics. This ensures sufficient amplitude to discharge adhesive products completely while avoiding excessive amplitude that would waste energy or cause product to be thrown away from the collecting bin
4Productivity
If intense shaking is applied to empty thick bags, then emptying effectiveness improves, but bags may tear and contaminate the product
Solution Approach 1:
The patent allows independent adjustment of shaking intensity and amplitude parameters, enabling optimization for thick bag materials. This provides sufficient mechanical action to empty thick bags effectively while controlling the intensity to prevent bag tearing and product contamination through precise parameter management
5Productivity
If shaking intensity is increased to handle difficult products, then product discharge improves, but product may break or dust cloud forms
Solution Approach 1:
The patent enables precise control of shaking intensity as an adjustable parameter, allowing optimization according to product fragility and adhesion characteristics. This ensures sufficient intensity to discharge difficult products efficiently while preventing excessive intensity that would cause product breaking or dust cloud formation

AI summary
The present invention refers to a dynamic shaking device for bags emptying. It has an inlet for the full bags (A), a discharge for the product contained inside the bags (B), and an outlet for the empty bags (C). The bags opening is made on the cutting zone by means of a cutting disc (2) with blade on the outer edge, located on the rotary shaft (1). This cutting disk is placed in a perpendicular direction in relation to the direction of the displacement of the bags. The present invention allows the simultaneous linear and circular motion as well as the motion in different planes of the bags to be emptied, since it has shakers composed of serpentine-shaped shaker elements (5), which may have central shafts (4). These shakers are arranged in parallel position in relation to the shafts (2) of the cutting zone. Shakers can be driven by motors (3).
