Solution Overview

Problem

Existing support posts for safety barriers in construction sites are often cumbersome to install, expensive, prone to unintentional dislodging, and difficult to transport and reassemble, with inefficient clamping mechanisms for fence panels.

Innovation Solution

A telescopic support post system with a spring-biased ceiling engaging member and a latch mechanism that allows secure attachment between ceiling and floor structures, and a fence lock for securing panels, enabling easy installation, secure locking, and efficient reconfiguration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If existing support posts are used to secure safety barriers, then the barriers can be installed between ceiling and floor structures, but the support posts are cumbersome to install and expensive to manufacture

Engineering Contradiction:
Improveease of installationVSAvoidcomplexity of support post
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The support post is divided into multiple segments including an outer tube, inner tube, and intermediate sections that can be independently manufactured and assembled. This segmentation simplifies manufacturing processes and reduces complexity while maintaining structural integrity for securing safety barriers between ceiling and floor structures.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The telescopic mechanism employs nested tubes where the inner tube slides within the outer tube, with intermediate sections nested between them. This nesting arrangement reduces the overall complexity of the support post while enabling easy extension and retraction for installation between different ceiling and floor heights.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Reliability

If existing support posts are used, then they can provide structural support, but they are easily intentionally or accidentally unlocked or dislodged

Engineering Contradiction:
Improvesecurity of barrierVSAvoidvulnerability to unlocking
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The support post incorporates a dynamic locking mechanism with a latch member that can be positioned in locked or unlocked states. The latch is biased by a spring to automatically engage with the telescopic mechanism, providing reliable security that resists intentional or accidental dislodging while still allowing controlled operation when needed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The locking mechanism is designed to automatically engage and lock the telescopic sections together through the latch member and spring bias system. This self-locking feature enhances reliability by ensuring the barrier remains secured without requiring constant external monitoring or intervention, while preventing unauthorized unlocking.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If existing support posts are used, then they can support safety barriers, but they are not easily removed and transported to different floors for reinstallation

Engineering Contradiction:
Improvereusability of barrierVSAvoiddifficulty of removal and transport
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The telescopic support post features movable inner and outer tubes that can be easily extended and retracted. This dynamic structure allows the barrier to be quickly disassembled by collapsing the telescopic sections, facilitating simple removal and transport to different floors for reinstallation, thereby enhancing reusability and adaptability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The segmented telescopic design with separable outer tube, inner tube, and intermediate sections enables the barrier to be easily broken down into manageable components for transport. This segmentation allows quick assembly and disassembly operations, making the barrier highly adaptable for relocation between different construction floors.

Inventive Principle:
Principle #1Segmentation

4Strength

If existing fence panels are wired together or attached through clamps, then adjacent panels can be connected, but the clamps or fastening mechanisms are frail, cumbersome or inefficient

Engineering Contradiction:
Improveconnection strength of panelsVSAvoidcomplexity of fastening mechanism
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The fence panel design integrates the fastening mechanism directly into the panel structure itself, merging the panel and connection elements into a unified component. This eliminates the need for separate external clamps or wires, providing strong panel-to-panel connections while significantly reducing the complexity and number of separate fastening parts required.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated fastening mechanism serves multiple functions: it provides strong structural connection between adjacent panels, enables easy assembly and disassembly, and maintains structural integrity during transport. This multi-functional design replaces frail or cumbersome separate clamps with a unified system that achieves both strength and operational efficiency.

Inventive Principle:
Principle #6Universality (Multi-functionality)
