Solution Overview

Problem

Existing locking constructions for agricultural machine frameworks, particularly those using simple clamping brackets, fail to effectively manage lateral forces and turning movements of trawl or disc-type springs, leading to operational and clamping strength issues.

Innovation Solution

A locking construction comprising a top bracket, counter-bracket, and clamping bolt that provides multi-directional locking effects, including vertical, horizontal, and rotational stabilization, using a concave shape, bosses, and tooth elements to securely clamp springs or resilient tooth elements to the framework, enhancing mechanical strength and resistance to lateral forces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If simple clamping brackets are used to clamp springs to the framework, then the device complexity is reduced and ease of manufacture is improved, but the mechanical strength against lateral forces and the stability against turning movements deteriorate

Engineering Contradiction:
Improvestructure complexityVSAvoidmechanical strength against lateral forces
Core Design Contradiction:
Device complexityVSStrength

Solution Approach 1:

The locking construction is divided into multiple functional components: a top bracket with concave shape and bosses, a counter-bracket with tooth elements, and a clamping bolt. Each segment performs a specific function (vertical locking, horizontal positioning, rotational prevention) that collectively solves the strength problem without requiring a single complex structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The solution addresses lateral forces and turning movements by adding multi-directional locking capabilities. The concave shape provides vertical locking, bosses provide horizontal positioning, and tooth elements prevent rotational movement. This multi-dimensional approach stabilizes the spring against forces from multiple directions simultaneously.

Principle #17Another dimension (Dimensionality change)

2Ease of operation

If simple clamping brackets are used to clamp springs to the framework, then the ease of operation is improved, but the reliability and safety in operation deteriorate due to operating and clamping strength problems

Engineering Contradiction:
Improveease of clampingVSAvoidoperational reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The top bracket is pre-formed with a concave shape and bosses that are designed to engage with the framework and spring in specific ways. The counter-bracket is pre-equipped with tooth elements positioned to prevent rotation. These preliminary structural arrangements ensure that when assembled, the components automatically provide multi-directional stabilization without requiring complex adjustment procedures during operation.

3Stability of the object's composition

If multi-directional locking effects are implemented to resist lateral forces and turning movements, then the mechanical strength and stability are improved, but the device complexity increases

Engineering Contradiction:
Improvestability against turning movementsVSAvoidstructure complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

Each component of the locking construction has specialized local features optimized for specific functions: the top bracket has a concave shape for vertical engagement and bosses for horizontal positioning; the counter-bracket has tooth elements specifically arranged to prevent rotation. This local specialization allows each part to be relatively simple in form while collectively providing complex multi-directional stabilization.

Principle #3Local quality
