Removable Lid for External Detection Device Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The maintainability of external detection devices in transportation apparatuses is compromised due to their integration with the front grill, requiring removal of the grill for adjustments, which complicates maintenance and increases the risk of damage from external shocks or water exposure.
Innovation Solution
A transportation apparatus design where the external detection device is positioned inside the outer surface, with a removable lid member that can be easily taken off from an abutment portion on the outer surface, allowing for internal pressing and preventing detachment during travel, and featuring a cover member to protect the irradiation surface from water and shocks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the external detection device is integrated with the front grill, then the structural integrity is improved, but the maintainability deteriorates
Solution Approach 1:
The front grill is divided into multiple sections: a fixed portion and a removable lid member portion. The lid member can be independently removed from the front grill without removing the entire grill structure, enabling easy access to the external detection device while maintaining the structural integrity of the remaining grill assembly.
2Reliability
If the lid member is securely attached to the front grill, then the reliability is improved, but the ease of operation deteriorates
Solution Approach 1:
The lid member is designed with dynamic attachment characteristics - it can be easily removed by pressing from the inside through the opening portion, yet remains securely attached during normal operation to prevent accidental detachment from shocks or external forces during travel.
3Measurement precision
If the external detection device is positioned on the outer surface, then the detection capability is improved, but the vulnerability to external factors worsens
Solution Approach 1:
The external detection device is nested within the transportation apparatus structure, positioned inside the outer surface. The lid member provides an additional protective layer, creating a nested configuration that protects the detection device from water and shocks while maintaining detection capability through the lid member material properties.

AI summary
A transportation apparatus includes an external detection device configured to detect an object. The external detection device is disposed further on an inner side than an outer surface of the transportation apparatus, on the outer surface, a lid member is attached to be removable and cover an irradiation surface when viewed from a perpendicular direction perpendicular to the irradiation surface of the external detection device, the lid member is formed so as to be removable from an abutment portion provided on the outer surface by being pressed from an inside, the outer surface is provided with an opening portion disposed close to the abutment portion, and the lid member is disposed so as to be pressable from the inside through the opening portion.
