Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the power supply is mounted in the base member, then the power supply can be securely accommodated, but the base member structure becomes more complex
Solution Approach 1:
The base member is segmented into a main body and a separate accommodating structure. The accommodating structure is designed as an independent component that can be attached to or integrated with the base member, allowing the power supply to be mounted without significantly complicating the overall base member structure. This segmentation enables modular design and easier manufacturing.
Solution Approach 2:
The accommodating structure is designed to nest within or attach to the base member, creating a compact integration. The power supply accommodating space is formed within the base member's structure, allowing the power supply to be securely mounted while minimizing additional structural complexity. The accommodating structure serves as a nested component that fits within the base member's overall design.
2Productivity
If the power supply accommodating space is designed with specific orientation, then the power supply arrangement efficiency is improved, but the design flexibility is reduced
Solution Approach 1:
The accommodating structure features an asymmetric design where the power supply accommodating space is oriented in a specific direction relative to the base member. This asymmetric configuration optimizes the arrangement efficiency by aligning the power supply with the pivot axis and radial direction, while the asymmetric shape itself becomes the design feature rather than a compromise of flexibility.
Solution Approach 2:
The accommodating structure utilizes three-dimensional spatial arrangement by orienting the power supply accommodating space along the radial direction and perpendicular to the pivot axis. This dimensional approach allows efficient packing of the power supply while maintaining design flexibility through the use of spatial geometry rather than rigid constraints.
3Quantity of substance
If multiple power supplies are accommodated in adjacent spaces, then the power supply capacity is increased, but the connection complexity increases
Solution Approach 1:
Multiple power supply accommodating spaces are merged into a single integrated structure within the base member. The accommodating structure serves as a unified component that houses multiple power supplies in adjacent spaces, eliminating the need for separate mounting structures for each power supply. This merging reduces connection complexity by providing a common interface and mounting mechanism for all power supplies.
Solution Approach 2:
The accommodating structure is designed as a universal component that can accommodate multiple power supplies of different configurations. The structure provides multi-functional capabilities including mechanical support, electrical connection interfaces, and spatial arrangement for multiple power supplies, reducing the overall system complexity by consolidating multiple functions into a single component.

AI summary
An operating device for a human-powered vehicle comprises a base member and an operating member. The base member includes an accommodating structure configured to accommodate a power supply defining a radial direction. The operating member is pivotally coupled to the base member about a pivot axis. The accommodating structure includes a power-supply accommodating space, into which the power supply is to be inserted along the radial direction and in an insertion direction which is non-parallel to the pivot axis.
