Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple backing plates of different thicknesses are used to accommodate different pattern mediums, then the adaptability to various pattern medium thicknesses is improved, but the device complexity and storage requirements increase significantly

Engineering Contradiction:
Improveadaptability to different pattern medium thicknessesVSAvoidcomplexity of managing multiple backing plates
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The backing plate thickness is made dynamically adjustable through a pluggable structure that allows the user to select and install different thickness specifications as needed, transforming a static fixed-thickness system into a dynamic adjustable one

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The backing plate is divided into modular segments with different thickness specifications that can be independently selected and plugged into the device, allowing flexible combination and adaptation to various pattern medium thicknesses without requiring a complete set of separate plates

Inventive Principle:
Principle #1Segmentation

2Strength

If a fixed retainer structure is used to withstand the 600kg stress between press rollers, then the structural strength is sufficient, but the adaptability to different pattern medium thicknesses is reduced

Engineering Contradiction:
Improvestrength of retainer structureVSAvoidadaptability to different pattern medium thicknesses
Core Design Contradiction:
StrengthVSAdaptability or versatility

Solution Approach 1:

The retainer structure incorporates a sliding mechanism that allows the press roller position to be dynamically adjusted along the sliding direction while maintaining the fixed structural strength, enabling adaptation to different pattern medium thicknesses without compromising the 600kg stress承受能力

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The retainer is designed with separable components including a fixed portion and a sliding portion, allowing the sliding portion to be adjusted to different positions for accommodating various thicknesses while the fixed portion maintains the overall structural integrity and strength

Inventive Principle:
Principle #1Segmentation

3Manufacturing precision

If repeated testing is performed to determine the correct number of backing plate layers for thin pattern mediums, then the pattern making quality is improved, but the working efficiency is significantly reduced

Engineering Contradiction:
Improvepattern making qualityVSAvoidworking efficiency
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

Multiple backing plate layers of different thicknesses are prepared in advance and can be quickly plugged into the device, eliminating the need for repeated testing during operation and allowing the user to directly select the appropriate thickness based on the pattern medium requirements

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The pluggable backing plate structure enables rapid switching between different thickness specifications during operation, transforming a static trial-and-error process into a dynamic quick-adjustment process that maintains pattern making quality while significantly improving working efficiency

Inventive Principle:
Principle #15Dynamics

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The machine enhances pattern making efficiency, reduces production costs, and improves the cleanliness of the production environment by allowing for quick and precise adjustments of press roller spacing to match specific pattern medium requirements.

Implementation Method 1

The speed reduction gear set includes a handle gear, a speed reduction gear or the speed reduction gear set to mesh with each other. The handle gear is rotated along with the handle. The speed reduction gear is connected with the first press roller or the second press roller to drive one of the two press rollers to rotate.

Methodology Applied
Scientific EffectGear mechanism: Gear

Implementation Method 2

The constant speed gear set includes a pair of a first constant speed gear and a second constant speed gear to mesh with each other. The constant speed gears are fixed on the roller axles of the first press roller and the second press roller, respectively. When one of the press rollers is driven by the speed reduction gear to rotate, the other press roller is driven by the constant speed gear to rotate at a constant speed.

Methodology Applied
Scientific EffectGear mechanism: Gear

Implementation Method 3

When the press rollers are rotated, the press rollers drive the backing plates to pass through the rolling surfaces of the press rollers.

Methodology Applied
Scientific EffectFriction: Friction

AI summary

A manual craft cutting machine comprises a housing (1), a template, a press roller, a retainer, a backing plate, and a drive mechanism. The press roller is composed of a first press roller and a second press roller. The press roller is rotated under restriction of the retainer. The retainer comprises a positioning retainer (3) and a sliding retainer. The positioning retainer (3) is provided with a slide groove. The sliding retainer is inserted in the slide groove and movable along the slide groove. The sliding retainer comprises a first sliding retainer (31) rotatably connected with the first press roller (4) and a second sliding retainer (32) rotatably connected with the second press roller (5). The manual craft cutting machine further comprises a press roller spacing adjustment mechanism. The press roller spacing adjustment mechanism comprises a shift adjusting mechanism for adjusting a large spacing between the press rollers and a fine adjustment mechanism for adjusting a fine spacing between the press rollers. The shift adjustment mechanism drives the first sliding retainer (31) to move along the slide groove, and the fine adjustment mechanism drives the second sliding retainer (32) to move along the slide groove, so that the spacing between the press rollers can be quickly and largely adjusted according to the needs, and a fine spacing adjustment can be achieved according to the needs.
