Solution Overview

Problem

Existing L-brackets for securing cameras on tripods are expensive, cumbersome, and inconvenient when cables are attached, as they hinder the camera's rotation by 90° and are not easily adaptable for portrait or landscape positions.

Innovation Solution

A double support plate with transversal inclined surfaces and wedge ribs that fit into ARCA or similar clamping elements, allowing stable fixation in any position without obstructing cable connections, and adaptable to various angles and sizes, including narrower options for smaller cameras.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If L-brackets are used to secure cameras on tripods, then the camera can be fixed in landscape or portrait positions, but the brackets become expensive and cumbersome to carry

Engineering Contradiction:
Improvecamera positioning capabilityVSAvoidbracket structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The L-bracket is divided into two separate support plates that can be independently attached to the camera. Each plate can be used separately for landscape or portrait positioning, eliminating the need for a single complex L-shaped structure. This segmentation allows the user to carry only the necessary plate for the current shooting orientation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Each support plate is designed with universal compatibility to work with both ARCA and Manfrotto clamping systems through standardized groove profiles. The plates can be used in multiple orientations and with different camera types, replacing the need for specialized L-brackets for each mounting scenario.

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

2Reliability

If L-brackets are used to hold cameras, then the camera can be secured to the tripod, but the cable connections become obstructed when rotating the camera by 90°

Engineering Contradiction:
Improvecamera fixation stabilityVSAvoidcamera rotation flexibility
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

By separating the mounting function into two independent plates rather than a single L-bracket, the camera can be securely mounted in either orientation without requiring rotation of a fixed L-shaped structure. The cable connections remain accessible as the camera body doesn't need to rotate 90° to change orientation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The support plates enable dynamic reconfiguration of the camera orientation without physical rotation of the mounted camera. Users can simply attach the appropriate plate for the desired orientation, maintaining cable accessibility while achieving position changes.

Inventive Principle:
Principle #15Dynamics

3Reliability

If standard width ARCA plates (38 mm) are used, then they provide sufficient clamping stability, but they extend over the camera body width making grip inconvenient

Engineering Contradiction:
Improveclamping stabilityVSAvoidcamera grip comfort
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The support plates are designed with non-uniform width distribution - narrower at the edges where they contact the camera body for improved grip, and wider in the central clamping region to maintain stability. This local variation in dimensions optimizes both grip comfort and clamping performance.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The plate width parameter is optimized to 25 mm instead of the standard 38 mm, changing the dimensional parameter to better fit modern smaller camera bodies while maintaining adequate clamping stability through the groove profile design.

Inventive Principle:
Principle #35Parameter changes

4Ease of operation

If narrower plates (25 mm width) are used for smaller cameras, then the grip is improved, but the clamping stability may be reduced

Engineering Contradiction:
Improvecamera grip comfortVSAvoidclamping stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The plate features a widened bottom part specifically in the clamping region where the grooves engage with the clamping element, providing enhanced stability. The sides remain narrower for improved grip, creating a local quality variation that satisfies both requirements simultaneously.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The plate design incorporates a thickness dimension of at least 8 mm, providing structural rigidity and clamping stability through the third dimension. This compensates for the reduced width while maintaining adequate grip comfort.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
