Solution Overview

Problem

The production of workpiece cut-outs with precise dimensions and angle relations is complicated, and existing guide templates require adjusting the depth stop when changing the penetration depth of the working tool, making handling cumbersome.

Innovation Solution

A guide template design where the depth stop and engagement protrusion are arranged on a carrier body, allowing the main-side stop to be adjusted independently without altering the depth-setting position, maintaining a consistent relation between the engagement protrusion and depth stop, thus simplifying handling and maintaining precise cut-out dimensions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the engagement protrusion is adjusted relative to the main-side stop surface to change penetration depth, then the penetration depth of the working tool is changed, but the depth stop must be readjusted simultaneously making handling complicated

Engineering Contradiction:
Improvepenetration depth adjustmentVSAvoidhandling complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The device is divided into independent functional modules: the engagement protrusion on the carrier body for depth setting, and the adjustable main-side stop for position setting. This segmentation allows each component to perform its function independently without interfering with the other, resolving the contradiction between adaptability and ease of operation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The penetration depth is pre-set by the fixed relationship between the engagement protrusion and depth stop surface before operation. This preliminary action eliminates the need for simultaneous readjustment during operation, simplifying handling while maintaining depth control capability.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If the main-side stop is adjusted to change main-side stop distance, then the position relative to engagement protrusion is changed, but the depth-setting position must be maintained constant

Engineering Contradiction:
Improvemain-side stop distance adjustmentVSAvoiddepth-setting precision
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The adjustment function is segmented into two independent systems: main-side stop position adjustment and depth setting. The main-side stop can be adjusted along the carrier body without affecting the fixed depth-setting relationship between the engagement protrusion and depth stop surface, thus maintaining precision while providing adaptability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The carrier body acts as an intermediary structure that carries both the engagement protrusion (for depth setting) and the adjustable main-side stop. This intermediary structure enables independent adjustment of the main-side stop while maintaining the constant depth-setting relationship, resolving the contradiction between adaptability and precision.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Manufacturing precision

If the depth stop and engagement protrusion are fixed relative to each other, then the depth-setting position is maintained, but adjustment of main-side stop distance is limited

Engineering Contradiction:
Improvedepth-setting consistencyVSAvoidadjustment range
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The system is segmented into a fixed depth-setting component (engagement protrusion relative to depth stop surface) and a movable positioning component (main-side stop). This segmentation maintains depth-setting consistency while allowing the main-side stop to be adjusted to different distances, providing both precision and adaptability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The main-side stop is designed to be dynamically adjustable along the carrier body, while the depth-setting relationship remains static. This dynamic element provides adjustment range and versatility, while the static element ensures manufacturing precision and depth-setting consistency.

Inventive Principle:
Principle #15Dynamics
