Solution Overview

Problem

Existing winding devices for binding straps lack portability and repositionability, as well as efficient independent storage and deployment mechanisms, limiting their usability and convenience in various load retention scenarios.

Innovation Solution

A portable binding strap winder with an integrated support frame, a rotatably positioned spindle, and a crank handle, along with a secondary strap arm and removable locking pin for secure rotation control, allowing for flexible mounting and storage of binding straps.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing winding devices are used, then strap winding function is provided, but portability and repositionability are lacking

Engineering Contradiction:

Improveportability and repositionabilityVSAvoiddevice structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The device is divided into separable components including a removable crank locking pin and a modular support frame structure. This segmentation allows the device to be easily assembled, disassembled, and repositioned, directly addressing the portability requirement while maintaining functional integrity

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The support frame includes a removable crank locking pin that allows the crank handle to be locked in position during operation and removed when repositioning is needed. This dynamic locking mechanism enables the device to transition between stationary operational state and mobile storage state, resolving the contradiction between stability during use and portability

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If integrated strap winding is used, then strap tensioning is achieved, but independent storage and deployment mechanisms are insufficient

Engineering Contradiction:

Improveindependent storage and deploymentVSAvoidusability and convenience

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The support frame serves multiple functions: it provides structural support during winding operation, acts as a storage container for the crank handle when removed, and enables portable deployment of the device. This multi-functionality addresses the need for independent storage and deployment while maintaining ease of operation

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The removable crank locking pin acts as an intermediary element that mediates between the crank handle and the support frame. It enables easy attachment and detachment of the crank, facilitating independent storage of the winding mechanism while maintaining operational convenience when assembled

Inventive Principle:

Principle #24Intermediary (Mediator)
