关于 Arc 椅子

Arc 是一款适用于日常坐具的多功能座椅。曲线塑造了这把椅子的每一个部分,从舒展的靠背到拱形的扶手。框架采用 16 毫米低碳钢管弯制而成,呈经过理性化处理的二次曲线弧形。座面、靠背与扶手由 18 毫米桦木胶合板经 CNC 数控机床切割成型,表面施以深色着色处理。椅子以两个半体的形式供应,通过螺栓连接组装,扶手可根据需要加装。其人体工程学比例参考了 25 至 35 岁使用者的人体测量数据。

独特属性: The Arc Chair is a multipurpose seating solution that combines aesthetics, functionality, and versatility to create a unique and adaptable piece of furniture.
The Arc Chair is characterized by its dynamic form, which seamlessly integrates arcs into every aspect of its structure. From the sweeping curves of the backrest to the gracefully arched armrests, the chair embodies a sense of movement and harmony. The arcs serve as a visual focal point and contribute to the chair's ergonomics and comfort.
尺寸与包装: Overall Dimensions: 550 mm x 550 mm x 730 mm
Seating height: 445 mm
Seat area: 450 mm x 430 mm
标签: Arc Chair, Curves, Biomorphic, Multipurpose chair
生产技术: The chair structure comprises a 16 gauge CRC Mild Steel Pipe of 16mm dia. A multi-axis pipe bending machine can bend this to shape, as all the curves are rationalised second-degree arcs. However, due to the limitations of the prototyping facility at the institute, the component had to be made in parts and welded later on to complete the whole. Threaded holes were made to align to attach the various elements using bolts.
The seat, back and armrests consist of 18mm thick birch plywood cut to shape in a CNC machine. The edge was routed to give it a smoothly finished edge. This was later polished with a dark stain and attached to the structure using D-nuts and bolts.
设计挑战: During the development of the Arc Chair, the creative challenge was to seamlessly integrate arcs into every aspect of the design while ensuring ergonomic comfort. One obstacle was to strike the right balance between aesthetics and functionality, ensuring that the chair's unique form didn't compromise its usability.
Access to information and technology played a vital role in overcoming obstacles. Extensive research on ergonomic principles, user preferences, and material properties was conducted. Advanced design software and prototyping technologies facilitated the exploration and refinement of design iterations.
Further challenges were faced while manufacturing the prototype, as the lack of availability of tech meant that each part had to be made separately and required a jig to hold the pieces together. Overall each challenge served as an opportunity for learning and reflection.
研究: Primary research
To get the relevant data for the Indian demographic and not necessarily rely on standards biased towards the Western body type.
Users aged 25 to 35 were selected, with a 50-50 split between male and female respondents.
Various anthropometric data were collected related to seating.
The data was further split into segments at 3-inch intervals, and an average was considered.
This aims to provide furniture inclusive of the target demographic.
灵感: The motive was to create a seating solution that captures the fluidity and elegance of arcs while providing ergonomic comfort.
The inspiration came from the idea of movement and harmony found in biomorphic forms such as the lotus, translating those qualities into the design.
The research consisted of studying carrying patterns and primary user data. Iterative design processes, such as sketching, 3D modelling, and physical prototyping, were employed to refine and validate the design concept.
项目周期: The project started in March 2023 at the National Institute of Design Ahmedabad as part of the student furniture design project and finished in May 2023.
操作流程: The chair consists of 2 easy to assemble halves which the provided bolts can attach. Above these halves, one can connect the backrest and the seat. Further, if required, the armrest can be attached to the sides by the smaller bolts provided.
