Roof-Mounted Camera Stay Layout for Low-Height Work Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protection mechanisms for working vehicles often struggle to accommodate camera units below the peripheral portion of the roof, especially in storage spaces with limited height, making it difficult to store vehicles with these mechanisms.
Innovation Solution
A protection mechanism for working vehicles that includes a roof, pillars supporting the roof, and a support stay connected to the pillars to orient and support a camera unit sideways below the peripheral portion of the roof, allowing for easy attachment and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the camera unit is attached to the upper portion of the rear of the roof, then the camera has a good viewing direction, but the working vehicle cannot be stored in storage spaces with limited height
Solution Approach 1:
The camera unit is repositioned from the upper rear portion of the roof to the lower peripheral portion of the roof, changing the vertical dimension of installation. This dimensional shift reduces the vehicle's effective height while maintaining surveillance functionality through the support stay structure.
Solution Approach 2:
A support stay is introduced as an intermediary component to connect the camera unit to the roof structure. The support stay enables the camera to be positioned below the peripheral portion of the roof, mediating between the roof structure and the camera unit to achieve both compact height and proper viewing orientation.
2Volume of moving object
If the camera is attached to a lower portion of the roof or between the peripheral portion of the roof and the frame, then the vehicle height is reduced, but the camera unit is difficult to attach due to limited space
Solution Approach 1:
The support stay serves multiple functions: it structurally supports the camera unit, provides a mounting interface for easy attachment, and maintains the camera's viewing orientation. This multi-functional design simplifies the attachment process while achieving the desired compact configuration.
Solution Approach 2:
The support stay is pre-configured with attachment interfaces and routing units before installation. The routing unit is pre-designed to guide transmission lines from the pillar to the roof, making the overall attachment process easier and more systematic.
3Ease of operation
If the support stay is positioned to allow easy camera attachment, then the camera can be installed below the roof, but the transmission line routing becomes complex
Solution Approach 1:
The routing unit acts as an intermediary component specifically designed to manage transmission line routing. It provides a structured path for cables from the pillar to the roof, simplifying what would otherwise be a complex wiring task through the support stay structure.
Solution Approach 2:
The transmission line routing is divided into segments: the routing unit handles the portion from the pillar to the roof, while other components manage their respective wiring. This segmentation of the routing system makes the overall installation more manageable and less complex.

AI summary
A camera unit (39) is easily attached below a peripheral portion of a roof (16). A protection mechanism (9) for a working vehicle (1) comprises : a roof (16) provided above an operator's seat; a pillar (45) which extends upward from a vehicle body (5) and which supports the roof (16); a camera unit (39) with a predetermined viewing direction; and a support stay (130) which is connected to the pillar (45), which orients the viewing direction of the camera unit (39) sideways, and which supports the camera unit (39) below a peripheral portion of the roof (16). The protection mechanism (9) comprises a plurality of the pillars (45) including a front pillar (46) which supports a front portion of the roof (16) and a rear pillar (48) which supports a rear portion of the roof; and the support stay (130) is connected to the rear pillar (48).
