Solution Overview

Problem

Existing panel mount systems for door or window frames are difficult to install and adjust, and they leave visible milled recesses, limiting alignment options and requiring immovable connections.

Innovation Solution

A panel mount system with a locking plate that can be adjusted in multiple directions using clamping screws and adjusting spindles, allowing complete coverage of recesses and easy alignment with the door or window frame.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a traditional aperture holder is used with a milled groove, then the holder can be inserted into the frame recess, but the milled recess remains visible after installation and alignment is limited

Engineering Contradiction:
Improvealignment capabilityVSAvoidvisible recess structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The invention extracts the visible milled recess from the final assembly by using a cover plate that completely conceals it. The aperture holder is designed with a cover plate that overlays the recess area, removing the aesthetic defect while maintaining the functional insertion capability into the frame recess.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The aperture holder is segmented into multiple functional parts: a locking plate for insertion into the frame recess, a base plate for structural support, and a cover plate for aesthetic concealment. This segmentation allows each part to fulfill its specific function while collectively solving both alignment and visibility issues.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If a non-adjustable aperture holder is used, then the installation process is simpler, but alignment in multiple directions is not possible

Engineering Contradiction:
Improvemulti-directional alignmentVSAvoidadjustment mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The aperture holder transitions from a static, non-adjustable component to a dynamic, adjustable system. The locking plate can be moved within the recess, and the cover plate can be positioned relative to the base plate, enabling alignment in multiple directions while maintaining structural integrity through the clamping mechanism.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The clamping screws act as intermediaries between the locking plate and the frame, and between the cover plate and the base plate. These screws provide the adjustment capability by allowing controlled movement and positioning, mediating between the need for adjustability and the requirement for secure fixation.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If the locking plate is secured tightly between base plate and cover plate, then the locking plate is prevented from being lost, but adjustment becomes difficult

Engineering Contradiction:
ImproveadjustabilityVSAvoidlocking plate retention
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The clamping screws provide a dynamic retention system that can transition between loose and tight states. During installation, the screws can be loosened to allow adjustment of the locking plate position, then tightened to secure the plate and prevent loss, providing both adjustability and reliability at different stages.

Inventive Principle:
Principle #15Dynamics
