Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If manual assembly of scaffolding is used, then workers can assemble the scaffolding with simple tools and procedures, but the assembly process is labor-intensive, time-consuming, and poses safety risks due to repeated climbing and carrying of components

Engineering Contradiction:
Improveassembly simplicityVSAvoidassembly efficiency
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The support frame employs linkage assemblies with pivotable connections that enable dynamic transformation between folded and expanded states. The linkage mechanism allows the frame to automatically adjust its configuration during assembly and dismantling operations, improving efficiency while maintaining structural integrity throughout the transformation process

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The support frame design allows the straight rod assemblies to be nested within each other when in the folded state, significantly reducing storage space and facilitating easier handling. The nested configuration enables compact storage while maintaining full functionality when deployed

Inventive Principle:
Principle #7Nested doll (Nesting)

2Ease of operation

If manual assembly of scaffolding is used, then workers can perform assembly tasks with basic equipment, but the repeated climbing and carrying of components consumes lots of energy and time

Engineering Contradiction:
Improveoperational simplicityVSAvoidassembly time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The support frame is pre-configured with linkage assemblies and pivotable connections that enable automatic expansion and contraction. This preliminary design allows the frame to perform assembly and dismantling actions automatically, eliminating the need for workers to repeatedly climb and carry components, thus significantly reducing assembly time and physical effort

Inventive Principle:
Principle #10Preliminary action

3Length of moving object

If manual assembly of scaffolding at higher levels is used, then workers can reach higher positions to assemble, but climbing while carrying things is dangerous and causes larger risk of work accident

Engineering Contradiction:
Improveassembly heightVSAvoidwork safety
Core Design Contradiction:
Length of moving objectVSReliability

Solution Approach 1:

The support frame is designed to be self-assembling through its linkage mechanisms that automatically expand and lock into position. This self-service capability eliminates the need for workers to climb to higher levels to manually assemble components, thereby maintaining the ability to reach high positions while significantly improving work safety by removing human workers from dangerous climbing activities

Inventive Principle:
Principle #25Self-service

4Length of moving object

If the support frame is in expanded state, then the scaffolding can be assembled at higher levels, but the frame occupies more space and is harder to transport

Engineering Contradiction:
Improveframe spanVSAvoidstorage space
Core Design Contradiction:
Length of moving objectVSVolume of moving object

Solution Approach 1:

The support frame utilizes dynamic linkage assemblies that enable automatic transformation between expanded and folded states. This dynamic capability allows the frame to occupy maximum space when needed for scaffolding assembly, then automatically contract to minimal space for efficient transportation and storage, resolving the contradiction between operational span and storage volume

Inventive Principle:
Principle #15Dynamics

AI summary

A support frame assembled automatically comprises multiple straight rod assemblies (10) and linkage assemblies (2). The straight rod assemblies (10) are arranged rectangularly. Each linkage assemblies (2) connects two straight rod assemblies (10) and comprises multiple upper rods (40, 41) connected to one joint seat (20), and multiple lower rods (50, 51) connected to one connecting seat (30). When attaching the joint seat (20) to the connecting seat (30), the support frame and the straight rod assemblies (10) are expanded. When detaching the joint seat (20) from the connecting seat (30), the support frame and the straight rod assemblies (10) are folded. Aforementioned actions can be achieved by operating a pressure ring assembly (90) attached on the straight rod assemblies (10). The support frame is convenient for storage, saves space, and can be automatically stacked and set up scaffolding with automated equipment.
