Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing hand-held tools, such as reinforcing bar binding machines, face challenges in accommodating various usage patterns due to inconsistent hook orientations, leading to user-specific variations in tool handling.

Innovation Solution

A tool design featuring a main body part with multiple locking parts angled towards the tool's center of gravity, allowing for hooks to be attached at different angles, and a detachable cover with similar locking parts, enabling versatile engagement with a to-be-engaged object.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single fixed hook attachment position is used, then the tool structure is simple, but it cannot accommodate various usage patterns of individual users

Engineering Contradiction:

Improveaccommodation of various usage patternsVSAvoidtool structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The tool divides the hook attachment function into multiple independent attachment positions (first hook attachment part and second hook attachment part) located at different locations on the tool body. This segmentation allows users to select different attachment positions based on their usage patterns, thereby accommodating various user preferences without significantly complicating the overall tool structure.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If the hook opening faces toward the center of gravity, then the tool orientation remains stable when hand is detached, but it does not accommodate different user gripping patterns

Engineering Contradiction:

Improveuser gripping patternsVSAvoidtool orientation consistency

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The tool provides multiple hook attachment positions with different orientations (one facing forward, another facing the center of gravity). This multi-functionality allows the same tool to serve different user needs: users who prioritize stability can attach the hook at the center-of-gravity-facing position, while users who prioritize ergonomic gripping can use the forward-facing position. Both functions are integrated into a single tool design.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If the hook is fixed at a specific angle, then the manufacturing is simple, but it cannot adapt to different user preferences in tool handling

Engineering Contradiction:

Improveuser preferences in tool handlingVSAvoidhook attachment configuration

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

Instead of creating a complex adjustable mechanism, the invention segments the attachment function into multiple fixed positions with different angles. Each position is designed with a simple fixed-angle structure that is easy to manufacture. Users can select the appropriate angle based on their preferences, achieving adaptability without requiring complex adjustable mechanisms.
