Solution Overview

Problem

Conventional screw bands made of plastic or rubber lack heat-insulation properties and pose difficulties in applying automatic coating and baking processes, especially for screws with washers, due to their material composition and design.

Innovation Solution

A screw band with a planar, elongated body composed of two paper layers and an adhesive layer, featuring waterproof and heat-insulation films, and positioning members with through holes and bendable supporting plates for secure screw placement, allowing for easy application of coating and baking processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If conventional plastic or rubber screw bands are used, then the screw band can be easily manufactured and used, but the screw band lacks heat-insulation effect and cannot be applied with coating and baking processes

Engineering Contradiction:
Improveease of manufactureVSAvoidheat-insulation effect
Core Design Contradiction:
Ease of manufactureVSTemperature

Solution Approach 1:

The screw band body is constructed as a composite structure with a paper base layer providing heat insulation and a waterproof film layer providing moisture resistance. This composite material approach enables the screw band to withstand coating and baking processes while maintaining ease of manufacture through layering common materials.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The invention changes the material parameters of the screw band body from conventional plastic or rubber to a paper-based composite structure. This parameter change enables the screw band to achieve heat-insulation properties suitable for coating and baking processes while maintaining manufacturability.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If screws are directly disposed on conventional screw band, then the screw band assembly is easy to carry and screws can be easily detached, but scattered screws are difficult to be automatically applied with coating and baking processes

Engineering Contradiction:
Improveease of detachmentVSAvoidautomatic coating and baking application
Core Design Contradiction:
Ease of operationVSExtent of automation

Solution Approach 1:

The screw band body is prepared in advance with positioning members that have through holes and supporting plates. These positioning members are pre-configured to hold screws in a fixed arrangement, enabling automatic coating and baking processes while maintaining easy detachment of screws when needed.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

Positioning members serve as intermediaries between the screw band body and the screws. These positioning members with supporting plates provide a structured interface that enables both automatic processing and easy manual detachment, mediating between the requirements of automation and ease of operation.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If washers are disposed around screws before coating and baking, then the screws with washers can be held on screw band, but the process becomes complex and cannot be automatically applied

Engineering Contradiction:
Improvefixing effectVSAvoidprocess complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The positioning members are segmented into distinct components: the body with through holes and separate supporting plates. This segmentation allows screws and washers to be positioned independently through the through holes and secured by the supporting plates, simplifying the overall process while maintaining reliable fixing.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The supporting plates are designed to be bendable, providing dynamic adjustment capability. This allows the supporting plates to flex during the coating and baking process and then return to their original position to secure the washers, enabling automatic processing while maintaining reliable fixing effects.

Inventive Principle:
Principle #15Dynamics
