Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door leaf actuation systems face challenges with design impairment and damage risk due to external cable transmission, which complicates assembly and increases maintenance costs while offering limited protection against mechanical and weather-related influences.
Innovation Solution
A device with a protective cover for the transmission means, integrated into the lever kinematics, provides a closed guide space to safeguard electrical and data transmission, allowing for easy assembly and maintenance, while also accommodating additional functional components, and features a flexible attachment mechanism for enhanced protection and user interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If transmission means are laid on the outside between door leaf and door frame, then electrical energy and data can be transmitted, but the design is impaired and the transmission means are exposed to damage risk
Solution Approach 1:
The protective cover integrates multiple functions: it protects the transmission means, provides a user interface, and serves as a structural component of the lever kinematics. By combining these functions into a single integrated component, the design achieves protection without proportionally increasing complexity.
Solution Approach 2:
The protective cover is designed as a multi-functional element that simultaneously protects the transmission means, provides a user interface for interaction, and integrates with the lever kinematics structure. This multi-functionality resolves the contradiction by achieving multiple benefits without linearly increasing complexity.
2Object-affected harmful factors
If transmission means are exposed externally, then assembly is simpler, but the transmission means are exposed to mechanical and weather-related influences
Solution Approach 1:
The protective cover is pre-assembled with the lever element in the factory, creating a protected guide space for the transmission means before final installation. This preliminary protection action ensures the transmission means are shielded from mechanical and weather influences while maintaining assembly simplicity through pre-integration.
3Reliability
If a protective cover is added to the lever kinematics, then the transmission means are protected, but the device complexity increases
Solution Approach 1:
The protective cover is integrated with the lever element through positive and/or non-positive fastening methods, merging the protection function with the existing lever kinematics structure. This integration achieves protection without adding independent complex subsystems.
Solution Approach 2:
The protective cover serves multiple purposes: protecting the transmission means, providing a user interface, and integrating with the lever kinematics. This multi-functionality ensures that the added component delivers multiple benefits rather than simply increasing complexity.
4Reliability
If cable transmission is used between door leaf and door frame, then electrical energy can be transmitted, but the transmission means are exposed to damage risk
Solution Approach 1:
The protective cover is pre-assembled with the lever element in the factory, creating a protected guide space for the transmission means before final installation. This preliminary protection action ensures the transmission means are shielded from mechanical and weather influences while maintaining assembly simplicity through pre-integration.
