Solution Overview

Problem

Placing protective caps on numerous exposed reinforcing bars at a construction site is inefficient due to the difficulty in carrying and handling multiple caps simultaneously.

Innovation Solution

A protective cap assembly with interconnected top plates and frangible connectors allows for easy separation and reconnection of caps, enabling efficient carrying and installation on reinforcing bars, with various connection types such as pins, webs, and snap-together features.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If protective caps are carried individually or in small groups, then safety protection is provided, but installation efficiency is reduced due to the lengthy process of placing caps on numerous bars

Engineering Contradiction:
Improveinstallation efficiencyVSAvoidtime for placing caps
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

Multiple protective caps are merged into a single interconnected assembly, allowing workers to carry and install multiple caps simultaneously rather than individually, thereby improving installation efficiency and reducing time loss

Inventive Principle:
Principle #5Merging (Combining)

2Productivity

If multiple protective caps are carried in each hand, then installation speed may improve, but handling becomes awkward and difficult

Engineering Contradiction:
Improveinstallation speedVSAvoidhandling ease
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

Multiple caps are combined into a unified assembly that can be carried as a single unit, maintaining high installation speed while significantly improving handling ease compared to carrying multiple loose caps

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The assembly is designed with separable connections between caps, allowing individual caps to be easily detached and installed while maintaining the integrity of the overall assembly during transport

Inventive Principle:
Principle #1Segmentation

3Stability of the object's composition

If protective caps are connected permanently, then carrying stability is improved, but ease of separation for installation is reduced

Engineering Contradiction:
Improvecarrying stabilityVSAvoidease of separation
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The connection between caps transitions from static/permanent to dynamic/separable, allowing the assembly to maintain stability during transport while enabling easy separation during installation through frangible or detachable connections

Inventive Principle:
Principle #15Dynamics

AI summary

An illustrative example embodiment of a protective cap assembly includes a plurality of protective caps each including a stem and a top plate. The top plates each have a plurality of edges. One of the edges of a first one of the protective caps is connected to an adjacent edge of a second one of the caps in a manner that allows for manually separating the first or second one of the protective caps from the assembly.
