Solution Overview

Problem

Existing canopy holding devices are difficult to assemble and may damage the canopy panel during installation, and they often fail to securely attach the panel without exerting excessive force.

Innovation Solution

A holding device with a screw body that is accessible from the outside, allowing for easy assembly by screwing into a recess in the canopy panel, and featuring a screw stop to limit immersion depth and prevent force transfer to the panel, along with support sections and contact elements for secure positioning and weather resistance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a screw connection is used to secure the canopy panel, then the panel is firmly attached to the holding device, but the canopy panel may be damaged during installation or use

Engineering Contradiction:
Improvesecure attachmentVSAvoiddamage to canopy panel
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

A screw body with a securing section acts as an intermediary between the holding device and the canopy panel. The screw body engages with a recess in the panel through a bearing surface, distributing forces and preventing direct damage to the panel while maintaining secure attachment.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The screw body design changes the interaction parameters by introducing a bearing surface and securing section that engage with the recess, transforming the force distribution from concentrated to distributed, thereby preventing panel damage while maintaining attachment reliability.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If the screw body is accessible from the outside for easy assembly, then installation is simplified, but the screw body may exert excessive force on the canopy panel

Engineering Contradiction:
Improveassembly easeVSAvoidforce on canopy panel
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The screw body is designed with a securing section that engages with the recess in the canopy panel before full tightening. This preliminary engagement prevents excessive force from being applied to the panel during the assembly process.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The design of the securing section and its engagement with the recess changes the force application parameters, limiting the maximum force that can be exerted on the panel while maintaining ease of assembly from the outside.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If the screw body extends into the receiving space to secure the panel, then attachment is achieved, but the screw body may transfer unwanted forces to the panel

Engineering Contradiction:
Improveattachment securityVSAvoidforce transfer to panel
Core Design Contradiction:
ReliabilityVSForce

Solution Approach 1:

The securing section of the screw body serves as an intermediary that engages with the recess in the canopy panel. This design allows the screw body to extend into the receiving space for secure attachment while the bearing surface prevents direct force transfer to the panel.

Inventive Principle:
Principle #24Intermediary (Mediator)
